Bag Chatter: An Interview with Uther Supply

Bag Chatter is a series of interviews that spotlights brands around the golf industry and the people behind them. We’re looking to make this a regular thing, so please comment and share through your medium of choice. If you have a brand and are interested in participating in these interviews, you can email [email protected] for consideration. This interview is with Daniel Erdman of Uther Supply.
Tell us about Uther. How do you pronounce that? What are you all about? How did you start?
It’s actually pronounced “other.” We’ve gotten that question a lot and, to be honest, we’re kind of OK with it. We wanted to brand ourselves as unique, so we think it fits well. We want to create products that no one else creates. That could be towels in unique prints or some other golf goods outside of that. We’re targeting the customer that wants to be different as well…people who want to demonstrate their unique personalities.
Forgive me for being a little direct, but golf towels may not strike a lot of people as being something a lot of people would start a business with. Were you seeing a lack of something in the marketplace somehow? What prompted you to start this company selling golf towels?
It may not be conventional and I definitely recognize that. Some of my friends have laughed at me for starting a golf towel business. I guess it hit me when I was working at private clubs (I have worked at The Thornhill Club and Ladies’ Golf Club of Toronto). When you work in the back shop and storage facility, you handle a lot of golf bags. I just noticed rows and rows of bags that all look the same and I thought it made a lot of sense to inject some personality into it. You know, people go crazy for how all the pros personalize their wedges and their bags. They buy towels and bag tags from courses like TPC Sawgrass and Pebble Beach to personalize their stuff, but in the end it all kind of blends together. Billy Horschel’s octopus-print pants at the 2013 US Open was something that always stuck out in my mind and in that moment when I was staring at all those bags, it all kind of came together in a way. I thought we could really add something to the marketplace.
What do you think differentiates your products from others in the marketplace? Why do you think people would buy your products?
We’ve already addressed the fact that we offer different and bold prints, but that’s obviously the first thing that most customers will notice. Beyond that, though, we put a lot of attention to detail into our products. We went through 40 different suppliers to get things right. My grandparents had a really successful flooring mat company when I was growing up. Watching them run the family business gave me the bug at a very young age to start my own business. It also taught me how much quality matters and getting the right suppliers and materials. It was so much more difficult back then without the internet, but now, a quick google search just does so much of the legwork for you.

Uther Supply’s golf towel lineup
Something that I think is very interesting here is you’re very young at only 22 years old. A lot of the people I’ve talked to recently have been in their twenties as well. Tell me a little bit about what it took to start this company. Did you have to secure an investment? A lot of people shy away from starting a company for fear of the hill being too steep to climb, if you will. Since you’re in the process of climbing it, what’s that actually like?
It definitely was difficult. The only outside funding I got were some grants and loans from business accelerator programs. Those helped tremendously. I remember having to place a very large order at my supplier at the same time my one of my funding opportunities was being processed. That particular one only had like a 20 percent acceptance rate, and if I didn’t get it, I honestly wasn’t sure how I was going to fund the order. The way everything happened to be timed, I had to I place my order before I heard back from my funding application to meet a deadline. It turned out I was accepted, so that was a relief, but it was definitely pretty stressful. You know, in the beginning, you’re working for months before you generate any income. You’re doing everything for the first time like sending stuff through customs, dealing with suppliers, collecting transactions, you name it. You’re bound to make mistakes along the way and when you have zero money coming in, the mistakes you make hurt so much more. You have no processes or systems in place. It’s something you need to accept for what it is and grind through it. Social media helped accelerate things quite a bit (including meeting my sales partner Luke through Instagram). Selling on Amazon and going to the PGA show last year gave us a boost as well. It’s hard to say what the hardest part is specifically. It’s just the grind in the beginning trying to get momentum behind it. Once you get over the hump, it’s really exciting and fun, but getting up to that point is definitely not easy.
It should also be mentioned that you’re based out of Canada. A lot of people would assume being in the Great White North would make the game of golf a challenging proposition. How long/short is your golf season in Ontario? How do you stay sharp over the Canadian winters? And what’s the craziest thing you’ve ever done to play golf when it’s far too cold for most of us? To what lengths will you go?
It can get interesting for sure. I first started golfing because of my hockey friends. Yes, a lot of us do play hockey up here. It was a natural transition for a lot of us to play hockey in the winter and golf in the summer. However, if you do happen to get a golf itch in the winter, you will have to get creative. It’s pretty easy to go to just an indoor simulator to practice. Sometimes I would go to Golf Town (our version of Golf Galaxy) to pretend to demo clubs in order to practice my swing. That can get you by for a while, but it’s not the same as hitting an actual golf ball and watching it fly through the air, you know? So when you get to that point, there’s a nice indoor/outdoor range near me with covered, heated hitting bays. Our golf season is from like April through October, so that leaves a lot of time in between. Golf vacations become necessary sometimes.
Before starting Uther, you alluded to your experience working at golf courses. First off, you must have some good stories. No need to mention any names, but what’s your favorite story from that stage of life? Also, what was it like to go from working at a club to having to court those golf clubs to become your customer, stock your products, etc? Was that really easy or really difficult?
Well, I have a bunch of stories involving golf carts. Just in case the old golf directors read this, I won’t give too many details. Working at a course is great. You can’t get a better “office” than going to the course every day. There’s nothing like watching the sunrise on a dew-covered golf course, especially when you’re being paid. Some of my best memories were after tournaments where three of us guys would clean like 80 golf carts. We would all have fun and get to know each other. It didn’t really feel like work.
In both instances (working for a course and now selling to them), it doesn’t really feel so much like work. It does take a lot of work, don’t get me wrong, but it doesn’t feel like drudgery, that’s for sure. The difference is that there’s a lot more behind the scenes work that I’m doing now. We recently did a towel for the San Francisco Public Golf Alliance in collaboration with State Apparel. It took us a lot of back and forth to get that product right, but once we did, we came up with a custom, one-off product that our customers really loved. And watching them react to it was incredible. Stuff like that really keeps you going.

This question is unabashedly inspired by (ahem…lifted from) one of Rick Shiels’ recent posts. (Giving credit where it’s due here). If you had to “Tin Cup” it (i.e. play a round of golf with only one club), what club would it be and how many extra strokes do you think it would take? So, if you were to play your home course, your normal score is what? And what would your “Tin Cup” score be, you think?
If I had to choose one club for a Tin Cup round, I think it would be a five iron. My home course (and the public golf course I worked for) is Richmond Hill Golf Club. It’s only like 6,000 yards, so I feel like I could totally get by with a five iron and get on any green in 3. I typically shoot like an 80-85. I don’t think I would be that far off the number honestly. I trust the five iron, but also, I know my course pretty well and I think that club would suit it nicely. Now that you ask, though, I feel like I’m dying to try it!
What tour pro would you most like to have a beer with? Not necessarily the guy you’d want to play golf with or pick his brain about the game. Who do you think is the most likeable guy on tour? Who would you most like to befriend, if you will?
I would definitely have to go with Rickie Fowler. He’s got a bold style for sure, but he owns it and I really dig that. I love that he congratulates the other guys on tour and is supportive of them when they win tournaments. He seems so humble. He’s also really adventurous. He’s into motocross. I’m not into motocross, but I love the adventurous spirit. He just seems like a really cool guy from what I can tell.
It’s almost hard to believe, but the PGA Merchandise Show is fast approaching (January 23-26, 2018 in Orlando, FL for those who don’t know). Will you be exhibiting? What are you most looking forward to? That question is, of course, about what steps you think Uther will take, but also, are you looking forward to anything specific from other manufacturers? What companies’ booths are you planning on going to?
We will definitely be at the show and we’re really looking forward to it. Come see us at booth 3988! I walked the show last year but wasn’t exhibiting, so I would go up to potential customers and pitch my products to them. That was a lot of work and it was quite stressful being out on a limb like that. We’ve been working on this year’s show since August and I think it’s going to be a ton of fun. We’ve got some really cool stuff planned. You also get to meet so many people there, which is just a blast. As far as other stuff I’m looking forward to, Greyson Clothiers is definitely at the top of the list. Charlie’s story is so interesting and I just love their products.

Lastly, what do you guys have in the works? Are there any product releases forthcoming? Tell people how to find you on website, social media, etc.
So, the big news is that we will be expanding beyond golf towels. We will be launching some gloves and hats that I’m really excited about. We have six different golf gloves as well as bucket and baseball hats we’ll be rolling out in some very fun prints and colors (because that’s what we do). Definitely a good idea to check out our website, which is www.uthersupply.com. The website has a link to sign up for our email list which will send out some discount codes from time to time. There will also be some exclusive and limited-edition products on the website at times too. @Uthersupply is our handle on all social media platforms. Business customers can reach us at [email protected] to collaborate with us on custom products. We’d love to have people come see what we’re about!

Equipment
Beyond limits: Carbon bending and the future of shaft manufacturing

My name is James, and I am an equipment junkie. Like many of you, I am also a (mediocre) golfer struggling to take my golf game to the next level. But since I’m not so keen on hitting the range or the gym, I’m always searching for the next big breakthrough to help me avoid excessive practice and golf lessons.
TLDR: I am back to report that I may have found the ultimate breakthrough involving how golf shafts are manufactured. It will sound mind-boggling and counter-intuitive, but the new technology involves controlling a shaft’s variables of weight, flex (CPM), and torsional strength (torque) all independently of one another. As if this alone doesn’t sound far-fetched enough, it also purports to control the subjective aspect of how stiff the shaft feels without affecting the other variables.
To the best of my knowledge, I never knew any of these were possible, but seeing (and feeling) is believing, though I’m still reeling from my recent experience. Moreover, I dare predict that the sheer novelty of this discovery has the potential to redefine the golf shaft industry as we know it.
Also, the article is long. You’ve been warned.
In A League Of Their Own
Over the years, I have reported on several golf innovations and technologies that made golfers sit up and take notice. Of those finds, let me briefly recap two products that especially stood out before I unveil my most recent discovery further below.
Starting at number three, I present the now-famous Autoflex shaft by Dumina. Introduced in early 2020 during the COVID epidemic, the small Korean company claimed that their shafts didn’t use any flex designations and are to be selected solely based on a golfer’s swing speed. Against conventional wisdom, the company claimed that a super flexible, ultralight shaft can improve distance and accuracy for golfers of all swing speeds. The AF shaft, with its mysterious Korea Hidden Technology (KHT), sounded too good to be true, but more often than not, golfers who braved the steep price and the hot pink color agreed that the shaft seemed legitimate. Many also credit it with creating a whole new category of soft and hyper-flexible performance shafts.
Next in the number two spot is the groundbreaking FreeFlex shaft from SJ Golf Lab, also out of Korea. When the FF shafts surfaced in early 2023, I first thought they were a slightly improved version of the Autoflex. At weights and flex even softer than the AF, the shafts also improved distance and accuracy at a lower price point than their counterparts.
Upon delving further, FreeFlex Technology (FFT) was far more amazing than I could have ever imagined. Against the norm, the inventor of FFT claimed that a shaft’s weight, flex (CPM), and torque are NOT relative to each other and that each variable can be controlled separately. According to SJ Lab, a lightweight, flexible shaft with a strong torque was possible, and vice-versa. The incredulous claim went largely unnoticed at the time, but the folks at SJ Lab recently decided to prove their technology by introducing the ultimate unicorn of a shaft.
Aptly named ‘Hammer Throw’ the rubber-like shaft featured a conventional shaft’s weight of 62g yet measured only 140 CPM to be incredibly soft and flexible. To top it off, it also featured a strong 3.5 torque similar to an S-flex shaft, all unlikely numbers that have never been combined in a single shaft before. The Hammer Throw proved to be a wonder shaft for slower swingers, helping to increase club head speed, distance, and even accuracy.
Ultimately, SJ Lab redefined the concept of ‘shaft customization’ by proving that a shaft’s WT, CPM, and TQ can be controlled independently to any degree.

Featuring SJ Golf’s FFT technology, the Hammer Throw and FF38 also caught the attention of many WLD athletes with swing speeds over 150mph.
Mind-Bending Revelation
The AF and FF shafts are indeed quite amazing, but what I’m about to share with you may be an even bigger discovery than both of them combined.
It was a Thursday afternoon in October when I arrived at SJ Golf Lab. I had just finished a round of golf that morning and felt flush after having bested my buddies on a tough track. I was to cover the story of a new line of putter shafts (based on the Chaos Theory in physics, no less) and was looking forward to seeing if it could help my putting.
I was making small talk with Dr. Choi, the inventor & CEO of SJ Golf Lab, when a courier arrived to hand him a sealed envelope. Inside was a patent certificate for a new golf shaft manufacturing process, which was to be featured in SJ Lab’s latest MetaFlex series of shafts.
“Oh, that sounds interesting” I said politely. “Is it like FreeFlex technology?”
What came next was a barrage of information so contradictory and yet so transformative in its revelation that I forgot all about the putter shafts.
Entering The Realm Of The Senses
Carbon Bending Technology (CBT) is the latest brainchild of Dr. Choi, the inventor of FreeFlex shafts. As incredulous as his FFT may seem, his new CBT technology takes it even further by stating that a fourth variable, the shaft’s level of firmness, can also be controlled independently of the other variables.
“CBT technology involves bending or wrapping carbon in a certain way to control how stiff a shaft feels, independently of weight, flex, and torque.” – Dr. Seung-jin Choi, inventor of CBT Technology
Take a moment to let that sink in. Not only is he saying that the objective values of WT, CPM, and TQ can be controlled in any manner desired, but he can also control the subjective aspect of how firm a
shaft feels.
If CBT technology is legitimately possible, the implications of his discovery are immense and may well change the way golf shafts are made. Needless to say, such a spectacular assertion begs the question, “How can such an improbable idea be possible?”
As I struggled to comprehend what I just heard, Dr. Choi handed me a shaft and asked me to try and bend it. Grabbing it at both ends, the shaft felt light and soft, and I was able to bend and flex it easily. I was then given another shaft and asked to do the same. The new shaft felt much firmer from the get-go, similar to what I’d expect from a typical S-flex shaft. When I said that the second shaft felt much stronger than the first, I was in for a rude awakening.
“They’re the same shafts” Dr. Choi said. “The only difference is that the second one was treated with the CBT process. Other than that, both are practically the same in CPM and torque.”
“What do you mean these are the same shafts? This one is definitely stiffer.” My eyebrow arched in puzzlement at such a blatant contradiction.
After all, I was holding both shafts in my hands, and no one in the world was going to convince me that these two had the same CPM and TQ measurements.
The skepticism in my voice must’ve been obvious as I was led to a measuring device. I wish I could’ve seen the look on my face at that exact moment when my eyes confirmed both shafts to have the same CPM and torque.

Two same-looking shafts measured similarly in CPM and torque, despite one feeling much stiffer.
Goosebumps broke out on my arms, and my brain felt numb. Stunned, I took turns grabbing each shaft by the ends and bent them over and over again. There was absolutely no doubt that one was stiffer than the other. It wasn’t even close. Yet, if the numbers don’t lie, how was I to reconcile the two empirical facts at odds with each other before my very eyes?
Seeing Is Believing… Or Is It?
After repeated measurements to ensure I wasn’t dyslexic, I regained enough sense to sit down with Dr. Choi to hear more about the sorcery of carbon bending.
ME: How does CBT differ from your earlier FFT technology?
CHOI: CBT came as a result of golfers loving our FreeFlex shafts with the FFT technology but wanting even more. The FFT allows us to control the weight, flex, and torque independently. We used this discovery to design a new breed of shafts that help all levels of golfers increase club head speed and distance. But some of the stronger, faster-speed golfers were eventually turned off from it, as they couldn’t get accustomed to the soft feel and flex. The fear of spraying the ball all over the course was just too much.
To solve this issue, I looked at many factors that led golfers to describe whether a shaft is soft or stiff. Similar to FFT, I soon discovered that a shaft’s stiffness is not relative to its CPM value. By reinforcing a shaft through a special process I call carbon-bending, it can be made to feel as stiff as I wish without changing the original CPM or torque.
ME: (blank stare)
CHOI: Did that answer the question?
ME: Uhh… no? What do you mean the CPM doesn’t change? If the shaft became stiffer, it means the CPM value must have increased, doesn’t it? How we perceive stiffness is subjective, so we measure the CPM value objectively with a machine. That way, we can compare the CPM values of different shafts to see which one is stiffer with the higher number.
CHOI: Normally yes, but like I said, how stiff the shaft feels does not have to correlate with the CPM. They are independently controllable. As I just showed you with the two shafts earlier, both measured at the same CPM and torque. It was only when I applied the CBT method to one of them that it became stiffer than before, as you have seen for yourself.
ME: Yeah, I’m still not sure how that is, feeling firm in my hands but the machine reading it as soft. Is this like the cat in Schrodinger’s box, where the cat is both alive and dead at the same time? This shaft is also both soft and firm simultaneously?
CHOI: Not quite. But how about this? What if the CPM measurement we currently use to gauge and compare stiffness between shafts is not the only method? What if there were other ways that we haven’t considered to control the feeling of firmness?
ME: So you’re saying you discovered a new way to objectively measure how we feel or perceive stiffness?
CHOI: I think it’s better to say that I realized that a shaft’s CPM and stiffness can be independent of each other, whereas before, we thought they were directly relative. It led to look for other ways to make the shaft firmer, which is what I did. In the process, it also made me think, what else are we missing? Maybe we’ve been limiting ourselves in believing there’s nothing new left to discover.
Shaft Manufacturing 101
According to Dr. Choi, the method of manufacturing carbon shafts has remained largely unchanged since 1979, when Taylormade first introduced the first graphite shaft that offered many advantages over conventional steel shafts. Since then, various new materials and technologies have made the shafts lighter and stronger, but the basic shaft-making process remains the same.
The making of a modern golf shaft consists of wrapping layers of prepreg (treated carbon fiber) sheets around a steel shaft (mandrel). As more layers are applied, the shaft becomes progressively thicker and heavier (WT), which makes the flex (CPM) stiffer and increases the torsional (TQ)
strength.

The characteristics of a shaft depend on the amount of material and how each layer is oriented on the mandrel. How this is done varies among OEMs.
The current method and its proportional relationship between WT, CPM, and TQ is widely accepted. However, it also presents a big challenge for shaft-makers, whose main goal is to make shafts that improve distance with more accuracy. This is because generating more club speed for more distance necessitates a light and flexible shaft; while improving shot accuracy requires the shaft to be firm in both flex and torsional strength.
To balance the trade-off as best they could, OEMs have continually researched new materials and higher-quality carbon, along with their own, often secret, ways of weaving and arranging the carbon prepreg. A good example to illustrate shaft improvement in this manner is the lighter 50-gram range of X-flex shafts, which were a rarity only a few years ago.
At least for now, 5X shafts seem to be the pinnacle of conventional shafts that can be made with the existing process.
Shaft Manufacturing 2.0
In physics, Force equals Mass multiplied by Acceleration (F=MA). The same can be applied to golf at impact, but since a golf club is designed to be in motion, its dynamic energy is calculated as Impulse=MAT, where T is the time the ball stays in contact with the club face.
Dr. Choi explained that increasing any of the three factors would transfer more energy to the ball (I).
In other words, by making the club head heavier (M), faster (A), and getting the ball to remain in contact with the clubface longer (T), the distance will increase as a result.
Now that we can get faster club head speed (FF shafts), how can the shaft be made to feel stiff while retaining a longer distance? The solution was surprisingly simple, as most discoveries tend to be at first.
“Imagine wearing a pair of skin-tight nylon stockings,” Dr. Choi said. “It’s tight, but you can still move and bend your knees easily.” Truth be told, I’d never worn stockings before, but I nodded to see where it would lead.
“If you were to put on one more, your legs will feel stiff, and with yet another, it’ll now be very difficult to even bend your knees,” he was building up towards a big reveal. “But no matter how stiff your legs now feel with the layers of stockings, you can still rotate them.” Come again?
“When you try to sit down, the legs will stick straight out like they’re in a cast, right? But you’d still be able to twist or rotate your leg [left and right] because the stockings are not exerting force in that direction.”
Dazed at the anticlimactic turn, I tried to recall the last time I had a cast but he plowed on. “The original characteristics of your legs don’t change because of the stockings. They’re still your legs, which are bendy and flexible.”
I may have missed a whole lot there, but loosely translated, CBT technology is like adding tight pairs of stockings to make a shaft feel firmer, but won’t change what the original shaft was in terms of
torque or CPM.
Helical Carbon Armour
Carbon bending involves a new step in the shaft manufacturing process, where a thin strip of carbon is helically wrapped tightly around the shaft to increase stiffness. This new sheath of armor will firm up the feel of the shaft but will not affect the CPM or torque. In addition, Dr. Choi’s in-depth research further showed that the width of the strip band and the spacing between the helical spirals all played a part in changing the characteristics of the shaft in minute ways.

Each shaft has been treated with CBT and using different carbon weave, band width, materials and alignment to display a unique characteristics that can be tailored to a golfer’s swing
The truly mind-blowing prospect of CBT, however, is its ability to create an endless number of unique shafts with specific performance characteristics. For example, the number of new shaft possibilities can reach tens or even hundreds of thousands, depending on various factors, including but not limited to the width and thickness of the band, the spacing and orientation of the helical spiral, the weave pattern of the band fabric, and each of the different materials that all of these factors can be applied to.
“Can you imagine a PGA tour pro being able to dial in a golf shaft to squeeze 99.9% of the performance potential from their favorite shaft, without giving up anything they prefer in WT, CPM, TQ, and now FEEL?” – SJ Golf Lab 2023
If It Looks And Barks Like A Dog?
Several days later, I returned to SJ Lab to test the new MetaFlex CBT shafts. The lineup consisted of three driver shafts of 5H, 6H, 6.5M, and iron ix90 shafts (H for high kick, M for mid-kick). Again, the MF series is designed for faster-speed golfers who swing at least 100mph to well over 120mph. I purposely asked not to see the shaft specs beforehand, as I wanted to remain neutral in determining how the new shafts felt and performed.
Waggling the 5H shaft first, it felt similar in weight and flex to a typical R-shaft. I usually average a smooth swing of about 95 mph with my FF38, but the 5H shaft instinctively made me try to swing harder to compensate for the firmer feel. The good drives launched high and carried as far, with spin between 1900~2000 rpm. As I warmed up, I was hitting it quite well, despite swinging a bit harder than usual.
I had grown accustomed to swinging smoothly and in tempo with FF shafts, so it felt good to swing hard again and not worry about the head catching up. The overall distance was comparable with my own driver at 240~250 yards, so I guessed the 5H specs to be about 220 CPM and close to 4.0 torque. On the downswing, the shaft reminded me of the many 5S shafts I had been using before being turned onto softer shafts. I imagined I could play it well, but struggle to keep it straight on the back nine when I gradually get tired.
Next, the 6H shaft felt like a conventional 5S on the waggle, but much stiffer like a 5X shaft on the actual downswing. I guessed it to be about 230~240 CPM and 3.5 in torque, as I was only able to turn the club head over about one-third of the time. I got a couple out to 240 yards but the rest of the shots varied from a fade bordering on a slice interspersed with low pulls. I felt the shaft demanded more speed for it to show its potential, and my slower speed wasn’t making it sing as it should.
Lastly, the MetaFlex 6.5M told me right away that it was out of my league. The waggle reminded me of a Ventus or a Tensei shaft, and the actual swing was even stiffer and closer to a 6X shaft. As expected, my shots were mostly pushed dead right, as I couldn’t effectively load the shaft with speed.
When I tried to force the head to turn over, I’d overcompensate to flip the wrist and pull it low left. The few that managed to land on the fairway barely traveled 210 yards with a noticeable decrease in ball speed. I can usually muster enough muscle to make a typical stiff shaft work over nine holes at least, but the 6.5M felt like an iron rod.
Overall, MF shafts’ waggles felt similar to conventional aftermarket shafts and felt even firmer during the actual swing.
I was now ready to see the actual spec measurements of the three shafts.

I could never have imagined such numbers corresponding to the firmness I experienced with MetaFlex shafts.
“There’s no way these numbers are the actual specs,” I protested. “These are softer than my FF38, so how…?” Hearing my voice hit a high pitch, I quickly closed my mouth. I already knew to expect something different, but this? Trying to reconcile the stiffness with such low numbers was just as difficult as it was the first time I encountered this phenomenon.
For lack of a better comparison, imagine picking up a cute kitten to hear it purr, only to be shocked at hearing it bark like a big angry pitbull with its tail stepped on. Does this mean I can no longer use phrases like “seeing is believing,” What will happen to “if it looks like a dog and barks like a dog?”
More importantly, what does this mean for the future of golf shafts?
Implications For The Future
Deep down, I believe every golfer wants to increase their driver distance. It doesn’t matter if you average 150 yards or 300 yards. As golfers, the need to hit it farther is in our DNA.
Since discovering that longer, easier distance (and accuracy to boot) is possible with the advent of AF shafts, I’ve never looked back. When FreeFlex shafts debuted earlier this year, I switched all my shafts throughout the bag and couldn’t be happier. I’ve received dozens of similar emails from golfers who read about my experiences and took the plunge, mostly to their pleasant surprise.
As amazing as the shafts are, some scoffed at the absence of such shafts on professional tours. If they’re so good, why aren’t they used more? After all, a distance gain of 10 yards on drives can mean as much as 5-10 percent closer to the pin on approach shots for shorter putts, which can translate to millions of dollars in winnings. In fact, dozens of pros from all major tours have tried them, some openly and some in secret.
As a recreational golfer, I can live with an occasional OB if it means consistently out-driving my friends. But an elite tour pro for whom a single stroke may be worth millions? Not a chance. Even the best can become a psychological wreck if the shaft flexed more than Arnold Schwarzenegger in his prime. Especially on the back nine of a major on Sunday afternoon.
But for the sake of argument, let’s suppose there exists a shaft that truly offers longer distance and accuracy of the soft FF shaft with the reassuring feel and playability of a stiff shaft. Better yet, what if your favorite shaft can be readjusted to fit all of your needs for maximum performance output and feel preferences? I’d bet my last Pro V1s that elite professional golfers will stop at nothing to have them tested and optimized to benefit each of their own swing metrics and performance. It’s in their DNA.
Dr. Choi also mentioned that he is nearing completion of his state-of-the-art swing and shaft diagnostic system, which can prescribe precisely the type of shaft (weight, flex, torque, feel, kick, kitchen sink?) needed for a player. And he builds it to that specification. Customization to the fullest.
As the company’s name implies, that is the ultimate goal of SJ Golf Lab and Dr. Choi, who hopes his shafts will come as a “Special Joy” for each and every golfer.
All in all, CBT certainly felt to me like the next evolutionary step in golf shaft technology.
So, what do you think? Can we trust the accuracy of the statements made by SJ Golf Lab? I would love to hear from other golfers and knowledgeable shaftoids in the industry, and what it can mean going forward.

Opinion & Analysis
The Wedge Guy: The science of spin

Over my 30-plus years writing about equipment and designing wedges, I must have been asked thousands of times: “How do I get more spin with my wedge shots?” That seems like such a simple question, but the answer is as far from simple as you can get. So, today I’m going to try to break down the science of spin into its separate components.
The amount of spin imparted to the golf ball in any wedge shot will be affected by three basic things:
- The ball you play
- Your personal swing skills
- The specific wedges you play.
Let’s look at each of them.
The Ball
One very simple way to improve the spin you get with your wedge shots is to play a premium ball with a soft cover. The harder and usually less expensive balls typically have a firmer core and a cover that is more durable but doesn’t allow as much spin. You should experiment with various balls to see which gives you the optimum combination of distance and spin.
Your skills
We all know those golfers who seem to spin the ball better than others. That’s because they have honed their skills to make an accelerating, pure strike to the ball most of the time, and to make contact very low on the clubhead – elite players wear out a dime-sized spot on their wedges that is center-face and between the 2nd and 5th grooves. My bet is your wear pattern is more the size of a quarter or even half dollar and centered several grooves higher. You’ll see later why that is so important.
Anyone can learn to be a better wedge player by engaging a golf professional and spending lots more time practicing your wedge shots. I highly recommend both, but also realize that spin is greatly affected by swing speed as well. A strong player who can hit a gap wedge 120 yards is likely to generate much more spin than an equally skilled player who hits gap wedge only 90 yards.
Now we get to the fun part – how the specific wedges you are playing will affect the amount of spin you can impart to any given shot.
The wedges
Grooves
Very simply, if you are playing a wedge that you’ve had for years, the grooves are likely well past worn out and are costing you valuable RPMs on every wedge shot. That said, no wedge brand has any measurable competitive advantage over another when it comes to groove technology. The USGA has not changed the rules on grooves in over a decade, and every premium brand of wedges is utilizing the best CNC-milling techniques to push those regulations to the limit. There’s just no story here. And my robotic testing indicates the total absence of grooves only reduces spin by 15-17 percent on a dry ball.
The Shaft
Yes, wedge shafts are that important. You should have shafts in your wedges that closely match the shafts in your irons in weight, material, and flex. This is particularly important if you have evolved to lighter and softer iron shafts. The exception to that is if you play X-flex shafts in your irons, take a tip from almost all tour professionals and opt for a slightly softer flex in your wedges.
Clubhead Design
What is much more important to make a wedge “spin-ier” is the design of the clubhead itself. While wedges really didn’t change much for decades, over the past few years, every major wedge brand has begun to position a bit more mass in the top section of the wedge clubhead. This repositioning of mass raises the CG a bit and improves the “gear effect,” which enhances spin on every wedge shot.
While they all are doing so to a different degree, most are held back by their reliance on their tour professionals’ input. Those elite players already spin the ball as much as necessary, and they don’t need or want more spin in their wedge shots. But that isn’t in your best interest.
This subject simply cannot be addressed without referencing my own work in wedge design for over thirty years. My wedges for Reid Lockhart, EIDOLON, SCOR, Ben Hogan and now Edison Golf have put increasingly more mass in the top half of the clubhead to help recreational golfers get more spin on all their wedge shots. I’m flattered that all major brands are finally starting to follow my pioneering of this design concept, because it works. (Caliper measurement reveals that none of today’s wedges even have as much mass above center-face as my original Reid Lockhart wedges did in the mid-1990s)
Regarding my reference to tour players’ skills and their dime-sized wear pattern earlier, by striking their wedge shots so low in the face, they are optimizing spin on their traditional “tour design” wedges, because it maximizes the amount of clubhead mass above the point of impact. We all know that “thinned” wedge shot that flies low but has sizzling spin – same concept.
To help explain how this CG placement affects spin, look at what has happened in drivers, fairways, hybrids, and now irons.
As the “launch monitor wars” have come to dominate club-fitting (and selling!), the “holy grail” of distance is high launch and low spin. The engineers are achieving this by continuously finding ways to put maximum mass low in the clubhead with carbon crowns, tungsten inserts and thin faces. But good wedge play is all about penetrating trajectories and optimum spin — and all that mass in the bottom of the wedge head is exactly the opposite of what is needed to deliver that ball flight.
Final thoughts
I’ll also leave you with this thought on getting maximum spin on your intermediate-range wedge shots. You are quite likely to discover you actually get more spin with your 52- to 54-degree wedge than with your higher-lofted 56 to 60. That’s because the ball is less likely to slide up the clubface, which causes loss of spin and higher ball flight. Give it a try to see for yourself.
This has been one of my longer posts, but the topic is worthy of a full explanation. I hope the “science of spin” is much less mysterious now.

Vincenzi’s RSM Classic betting preview: Experienced heads likely to contend at Sea Island

The final full-field event of the 2023 fall season has arrived. The PGA TOUR heads just south of Augusta for the RSM Classic at Sea Island Golf Club (Seaside and Plantation courses) in St. Simons Island, Georgia.
Each golfer will play three rounds on the Seaside course and one round on the Plantation course.
The Seaside course is a par-70 layout measuring 7,005 yards, and the Plantation course is a par-72 setup coming in at 7,062 yards. The Seaside course, which was redesigned by Tom Fazio, plays more like a coastal links, while the Plantation course is similar to a tree-lined parkland course. Both feature Bermudagrass greens and will be very scorable. The past five winners of the event have all finished between -19 and -22.
Some notable players in the field include Brian Harman, Ludvig Aberg, Si Woo Kim, Akshay Bhatia, Cameron Young, Billy Horschel, Matt Kuchar, Russell Henley, Taylor Pendrith and Corey Conners.
Past Winners at The RSM Classic
- 2022: Adam Svensson (-19)
- 2021: Talor Gooch (-22)
- 2020: Robert Streb (-19)
- 2019: Tyler Duncan (-19)
- 2018: Charles Howell III (-19)
- 2017: Austin Cook (-21)
- 2016: Mackenzie Hughes (-17)
- 2015: Kevin Kisner (-22)
Let’s take a look at several metrics for Sea Island Golf Club to determine which golfers boast top marks in each category over their last 24 rounds:
Strokes Gained: Approach
The greens at Seaside are big, so it will be important to stick approach shots close to avoid having to make difficult two-putt par saves. In what should be a birdie-fest, golfers will need to stick their approach shots to contend.
Total Strokes Gained: Approach in past 24 rounds:
- Sam Ryder (+24.8)
- Russell Knox (+22.4)
- J.T. Poston (+20.3)
- Eric Cole (+18.8)
- Alex Smalley (+18.4)
Good Drives Gained
Length really isn’t a factor at either course. Looking at the past winners at Sea Island, they’re all accurate golfers off of the tee who know how to find the fairway. However, over the past few years, “Good Drives Gained” has been a much more predictive statistic at this event than “Fairways Gained.”
Total Good Drives Gained in past 24 rounds:
- Russell Henley (+22.7)
- Brendon Todd (+21.8)
- Tyler Duncan (+21.7)
- Martin Laird (+20.6)
- J.J. Spaun (+20.5)
Strokes Gained Putting: Bermudagrass
This tournament could become a putting contest if the winds aren’t strong this week. Historically, the winners of the RSM Classic are great Bermudagrass putters (Simpson, Kisner and Hughes).
Total Strokes Gained: Putting on Bermuda in past 24 rounds:
- Maverick McNealy (+27.7)
- Chad Ramey (+25.3)
- Martin Trainer (+23.0)
- Justin Suh (+22.7)
- Taylor Montgomery (+22.5)
Birdie or Better Gained
With birdies (and potentially some eagles) likely to come in abundance, pars aren’t going to cut it at Sea Island. I anticipate the winning score to be close to -20, so targeting golfers who go low is the right strategy here.
Total strokes gained in Birdie or Better Gained in past 24 rounds
- Eric Cole (+31.4)
- J.T. Poston (+21.3)
- Ludvig Aberg (+20.9)
- Luke List (+20.7)
- Justin Suh (+16.1)
Strokes Gained: Par 4 (400-450)
With eight of the par 4s on the Seaside course measuring 400-450 yards, I’m looking to target golfers who excel on par 4s of this length.
Total strokes gained in category in past 24 rounds:
- Russell Henley (+21.1)
- Denny McCarthy (+13.4)
- Matthias Schmid (+12.8)
- Callum Tarren (+12.6)
- Ryan Moore (+11.4)
Statistical Model
Below, I’ve reported overall model rankings using a combination of the five key statistical categories previously discussed.
These rankings are comprised of SG: App (25%); Good Drives Gained (21); SG: Putting Bermudagrass (21%); B.O.B (21%); and SG: Par 4 400-450 (12%)
- Russell Henley (+2200)
- Sam Ryder (+9000)
- Chesson Hadley (+6500)
- Brendon Todd (+5000)
- Eric Cole (+3500)
- J.T. Poston (+3500)
- Stephan Jaeger (+4000)
- Matthias Schmid (+6000)
- Brian Harman (+2000)
- Austin Smotherman (+25000)
2023 RSM Classic Picks
Matt Kuchar +4000 (DraftKings)
There are plenty of players at the top of the odds board who have a strong chance to contend this week, but few have had the recent repetitions that Matt Kuchar has had. The veteran is in fantastic form and felt as if his game was in great shape heading into the World Wide Technologies Championship, where he came agonizingly close to victory.
Kuchar has three top-19 finishes in his last four starts worldwide, including the runner-up in his most recent start. At one point, he had a six-shot lead before making a disastrous quadruple bogey on the 15th hole during his third round. Many expected Kuchar to struggle on Sunday after blowing such a big lead, but he performed admirably and would have won if Erik Van Rooyen didn’t shoot a ridiculous -8 on the back nine.
The 45-year-old currently lives in St. Simons, Georgia so will be right at home playing at Sea Island this week. His history at the course isn’t as spectacular as one would think given how well the course fits him on paper, but he does have four top-30 finishes at the event since 2013.
In five of Kuchar’s six wins since 2012, he’s had a top-5 finish in one of his three previous starts leading up to the win. I believe his start at the WWT was a foreshadowing of a looming victory.
Billy Horschel +4000 (DraftKings)
After struggling for much of the 2022-2023 season, Billy Horschel has finished the top 20 in five of his past six worldwide starts including a T14 finish in his most recent start at the Alfred Dunhill Links Championship in October.
Horschel hasn’t played the RSM Classic with regularity but finished in 2nd place at the event back in 2016 where he lost to Mackenzie Hughes in a playoff. The course is a perfect fit for Billy, who’s not overly long off the tee and putts incredibly well on Bermudagrass.
Billy will come into the event as motivated as ever to contend on a course that he should be able to pick apart. With seven career PGA Tour wins, there’s no doubt that Horschel is a closer who will be able to keep his composure down the stretch.
Harris English +6000 (DraftKings)
After a 2021 Ryder Cup appearance, Harris English has had an inconsistent two seasons on the PGA Tour. However, the Sea Island resident finished the season on an encouraging note, finishing 10th at the BMW Championship.
English has a mixed history at Sea Island, but he does have a 6th place finish in 2020. He finished 29th last year, but a final round 65 may be an indication that the 34-year-old figured something out at the course that he grew just a few hours away from.
It’s a bit concerning that English has been off since August, but he’s played well off of layoffs in the past. Last year, he finished 9th at the Fortinet off a 6-week break. In 2021, he won the Sentry Tournament of Champions off of a 5-week break. This break has been a bit longer, but the extra time may not be a major detriment.
Enlgish is a better player than he’s shown over the past 18 months, and I believe he’s in store for a resurgent season that may start this week in Sea Island.
Taylor Pendrith +6500 (DraftKings)
Taylor Pendrith is in fantastic form. In his past three starts, he’s finished 3rd, 15th and 8th. Despite not seeming like a great course fit at Sea Island on paper, he’s had some great history at the course throughout his career.
Last year, Pendrith finished 15th at the event, gaining 5.4 strokes on approach. He also came into the event while playing some below average golf and still managed to hit it great at Sea Island. In 2021, he finished 26th despite missing the cut in two previous starts as well as the following start. I believe now that the Canadian is coming into the event playing some incredibly consistent golf he should be a serious threat to contend deep into the weekend.
Ben Griffin +7500 (DraftKings)
Just a week ago, Ben Griffin was 22-1 and one of the betting favorites at the Butterfield Bermuda Championship. Although some top end players such as Ludvig Aberg, Brian Harman and Cameron Young have been added to this field, I still believe the drop all the way down to this price gives Griffin a ton of value this week.
The North Carolina hasn’t built up an extensive course history at Sea Island just yet, but he did finish 29th at the event last season. The 27-year-old fired an opening round 65 to start his week and then shot two more rounds in the 60’s after a second round 71. His experience last season should be helpful in his pursuit of a victory this time around.
Sea Island should suit Griffin perfectly. In his past 24 rounds, he ranks 15th in the field in both Strokes Gained: Approach and in Strokes Gained: Putting on Bermudagrass. His sharp iron play and ability to hole putts on Bermuda make him an ideal candidate for to contend at Sea Island.
Alex Smalley +8000 (DraftKings):
The past five events in the PGA Tour’s swing season have given us winners who’ve already won on Tour multiple times. The fa oll is typically a time for first-time Tour winners to shine, and among the top candidates to accomplish that this week is Alex Smalley.
Smalley has contended a few times thus far in his career and one of those times was at last year’s RSM Classic. A consistent effort of 67-66-67-67 resulted in the Greensboro, North Carolina resident finishing in a tie for 5th place for the week. It’s no surprise that Smalley likes Sea Island given the amount of golf he’s played in the area and his knack for playing well on shorter courses.
The Duke graduate is beginning to round into form, finishing 30th last week at the Butterfield Bermuda Championship fueled by a final round 65 (-6). Smalley has done his best work on easier courses and the course should provide plenty of birdie opportunities for the 25-year-old.
Kevin Kisner +25000 (DraftKings):
Kevin Kisner has been playing incredibly poorly by his standards since his win at the Wyndham Championship in August of 2021, however Camilo Villegas’ win last week showed us how quickly things can change.
Kisner has shown some minimal signs of improvement during the fall season, finishing 62nd and 51st in his two starts at the Fortinet Championship and the Sanderson Farms Championship. More importantly, Kisner gained 1.8 strokes on approach at the Country Club of Jackson, which was his best approach performance since November of 2022. Going back to the Villegas example, while he was in the midst of a twelve-start stretch where he didn’t finish better than 54th, the Colombian gained 4.0 strokes on approach in a missed cut at the Sanderson Farms Championship in a missed cut. Clearly, he found something and went on to finish 2nd and 1st in his next two starts.
If there’s a course that Kisner may be able to find “it” on, it’s Sea Island. Kisner is a former Georgia Bulldog who’s won here in 2015, lost in a playoff in 2020 and has two additional top-7 finishes since his win. At long odds, “Kiz” is worth a sprinkle on one of his favorite tracks.
