How a golf club feels is usually a very important attribute for golfers, especially better players, and there are clearly very big differences in feel across clubs. However, there are a lot of misconceptions about what really causes a particular feel.
It is important to note that the golfer defines what feel means to him or her and whether a club feels “good” or “bad.” The following is my attempt to explain a bit more about where feel comes from.
What are we actually feeling?
It’s probably best to start with a quick summary of what you feel when you take a swing. It’s basically a combination of two things: the sound created by high-frequency vibrations in the club head due to impact with the ball — typically a few thousand Hertz — and the vibrations that travel up the shaft, through the grip and into your hands. Those vibrations are much lower, typically tens to hundreds of Hertz.
Much of the sensation that is attributed to feel is actually the sound of the head. Any club has a distinct natural frequency and therefore a sound “signature.” Furthermore, off-center hits change that sound slightly and give a player the ability to discern the mishit, or what you would call feedback. We ran a test about 10 years ago that involved players hitting shots while wearing noise-cancelling headphones, and it became very difficult for them to distinguish any differences in feel from shot to shot or club to club.
The vibrations felt in the hands after impact are still an area of active research for us, but since they come up the shaft and through the grip they are actually more a function of those two components than the head. We still offer the Cushin insert, which dampens vibrations in the shaft after impact and helps a lot of golfers for whom those vibrations can cause pain and injuries. Also contributing to feel is the force felt in the hands during the swing and this is basically a function of the club weight and flexibility of the shaft.
These days in our player tests we will ask for feedback on how a club feels with regard to the weight and balance as they pick it up, how it feels during the swing, and also how it feels and sounds at impact. They can all be quite different.
What can be difficult for a club manufacturer is the range of sensations people want to feel. Some players want a lot of feedback to let them know they didn’t catch a shot in the middle of the face. Some don’t. Some like a powerful sound, others like something a bit more muted.
Do forged clubs really feel better?
There are some significant differences in sound and feel between most forged blade irons and most cast cavity-back irons. These differences, however, aren’t the result of manufacturing technique. Take a look at Figure 1 comparing the frequency response (basically the sound signature) for a forged 5-iron versus a cast 5-iron of exactly the same design from a paper titled “The Comparison of Forged Heads to Cast Heads for Golf Clubs” written by the Mechanical Engineering Department at Virginia Tech University. The conclusion of the paper was that for clubs with a similar material and a similar geometry there isn’t any real difference in sound or feel between forged and cast club heads.
We ran a similar experiment that has become semi-legendary over the years in the engineering department. We made S59 6-irons using the same basic material and geometry in cast and forged versions. A test was conducted with 15 of our tour staff and only one player was able to successfully identify which iron was forged and which was cast.
It’s about material and geometry
So if it’s not the forging process that leads to the soft feel, what is it? The properties that really affect the frequency of vibration are mass and the elastic modulus of the material. Elastic modulus is essentially the force needed to permanently stretch or compress a substance. This is similar to, but not the same as hardness. Within reason, harder and softer metals won’t necessarily sound much different — it depends on the elastic modulus. Titanium alloys can be made to have a similar hardness as steel, but a much lower elastic modulus. On the other hand, many of the different types of steel used in golf clubs have a somewhat similar modulus, but vary quite a bit in hardness.
The other property I mentioned, mass, makes the biggest difference in irons. If we’re comparing two 7-irons, the total head mass is likely to be very similar, but the placement of that mass will change the sound significantly. Figure 2 shows toe views of a typical cavity iron and a blade iron. It’s not hard to imagine that the iron with perimeter weighting (the cavity back) will vibrate at a different frequency to the iron with more mass in the middle of the club (muscle back). It’s the geometry of these clubs that differentiates their sound, not whether they are cast or forged.
The historical context
Clearly, the perception is still out there that a forged club feels softer than a cast club. Even here at PING we did an experiment recently where we took two identical S55 irons and etched “forged” on one of them. In the test, one in three players reported a softer feel from the club that had forged written on it, so just the word “forged” creates a particular thought in a golfer’s mind. The reality is that both forging and casting technology in golf have come a long way in the past few decades, and the lines between what manufacturers can do with forged and cast products have become very blurred.
I do still run into a lot of golfers who have the perception that cast clubs are harder and therefore can’t be bent for lie angle. They must have not seen PING’s 10-degree color code chart, which made its debut in the 1970s. The point is that perceptions take a long time to change.
The best thing golfers can can do is keep an open mind and actually experience the feel of different clubs themselves.
The Wedge Guy: Plenty to be thankful for
This has always been my favorite week of the year, well, at least since I got old enough to understand that Christmas gifts do not just “appear” out of nowhere. I think that was about 60 years ago! This is the week of the year where, hopefully, we all take time to ponder the wonderful blessings of our lives.
No matter what 2022 might have brought you, I’m sure you can find at least a handful of blessings to be thankful for. My favorite holiday movie is a 1942 Bing Crosby/Fred Astaire film called Holiday Inn. If you haven’t seen it and enjoy old movie musicals, you might make it a “must see” this season. Besides being the movie where the classic White Christmas was introduced, there is a wonderful song for Thanksgiving called Plenty To Be Thankful For. It’s also a favorite of mine.
As I ponder my own year and the 70 years before it, I realize I have so many wonderful things to be thankful for. That starts with my blessing of good health. I find it remarkable to be on the north side of 70 and still have no issues. No prescription drugs. Only one visit to the hospital in my life, the result of a motor scooter incident when I was 13. A fabulous Mom and Dad, small town upbringing. A lifetime of great friends and the blessing of living in a small town on the Texas coast. And most recently, the entry of a great lady into my life that makes it all so very much better.
I have the opportunity to run a fledgling custom wedge company, Edison Golf, which allows me to challenge the entire category with different thinking. And I love writing this column every week to share the many lessons learned and observations made in this 40-year career in the golf club industry.
There are just so many things I cannot list them all. But right there with them is the blessing of the strength and flexibility to still move the golf ball around pretty good. To be able to still play to a low single digit handicap from the regular tees (no ‘senior tees’ for me, thank you), and test courses from the back tees occasionally is fun.
That last blessing comes straight from God, of course, but I “help Him out” by making stretching and fitness a part of my daily regimen for over 30 years. And that is something anyone can do to improve their golf scores.
As we all face the “off season” (even here in South Texas it gets cold and rainy occasionally), you can make the decision to have lower golf scores to be thankful for this time next year. Just because you are cooped up inside for the next few months doesn’t mean you have to forego golf and preparation for next year can begin right now.
I believe flexibility is more crucial to stronger shots and lower scores than strength. A simple internet search can turn up dozens of good guides to stretching for a longer, fuller and stronger golf swing. If you add a bit of endurance and strength training to that, it’s amazing what will happen to your golf fortunes. Nothing more complex than a daily walk and swinging a weighted club daily or several times a week will pay off big dividends when you can get out on a winter golf vacation or next season starts.
I hope you all have a wonderful and blessed Thanksgiving, and I look forward to another year of being able to share my lessons from a lifetime in golf and over 40 years in the golf equipment industry. Happy Thanksgiving to all!
2022 Fortinet Australian PGA Championship: Betting Tips & Selections
Is Cam Smith in Oz the Jon Rahm of the Spanish Open?
The recent, dominating T2/winner of the DP World Tour Championship went off at around 9/4 to beat Tommy Fleetwood, Min Woo Lee and company in Madrid in October, eventually sauntering home by six shots and delighting home fans supporting his third win at his home Open.
This week, Smith looks like going off at much bigger (at 7/2) to beat a slightly fuller depth of field, again including Min Woo, to win his third Australian PGA, after going back-to-back in 2017 and 2018.
There is little left to say about the winner of the 150th Open Championship in terms of class, summarised by the run of T2/T10/T3 at the three most recent Masters, as well as wins at the Sony Open, Tournament of Champions and The Players.
Of course, his career year has also been hot with controversy, denying a move to LIV and then vehemently defending his right to join the Greg Norman-led tour a couple of weeks later, but that’s not our concern as bettors. Indeed, look at the way his presence has been received back home.
Smith’s local Brisbane Times reports that the 29-year-old superstar was the first golfer to be awarded the ‘keys to the city’ and will also probably get his desire of a LIV event in Queensland.
He’s huge news back home, and if we are looking back at that Rahm comparison, looks pretty big at over 3/1.
Smith, though, is a grinder, no matter how good of one, and whilst wins have come in decent numbers under par, he tends to win when the short game simply outlasts everyone else in tough conditions. I’m not certain he gets that here, where the winning score was 22-under last time (in January 2022), and examining his impressive victories, it’s worth noting that none of his six PGA Tour victories have been by more than a single shot, with his second Oz PGA by just a stroke further.
You can count the LIV victory as better than I do if you like. No complaints on that score, but following that win he’s gone 42nd and 22nd on LIV – beaten by a lot less a player than he faces this week.
The filthy each-way doubles look certain to be popular, with Smith across the card from Joburg fancies Bezhuidenhout and Lawrence, but in a light betting heat, I’ll take a chance with just a couple of wagers.
Just one outright for me this week.
Golf form site, tour-tips.com rates Ryan Fox the number one this week, a short-head over Smith, and whilst he isn’t quite that elite class, his form shows he is plenty good enough to beat the favourite on his day, and hasn’t that much to find in comparison to Adam Scott, MIn Woo and Cam Davis, all of whom are rightfully respected and popular.
Fox is easy to precis.
In what has been a stellar season for the always-promising Kiwi, the 35-year-old has improved from around 200th in the world rankings at gthe start of ’22, to a current ranking well inside the world’s top-30, and certain of invites to all the most desired events.
Fox waltzed home by five shots in the desert at Ras Al Khaimah and won again by a stroke at the Dunhill Links, an event including tournament stalwarts Rory McIlroy, Tyrrell Hatton and Tommy Fleetwood. In between, Fox posted eight top-10 finishes including running-up in Belgium, at the Dutch Open, Irish Open and, just a couple of weeks ago, by a shot to Fleetwood and one of the latter’s favourite courses, the Gary Player GC.
Fox went into last week’s DP championship as a live contender for the title, which, given his commitment to the European Tour, would have been richly deserved. Perhaps that’s too political for here, though.
Either way, despite starting slowly in Dubai, he made his way up to 19th after four steadily improving rounds, enough to hold off Rahm from swapping places at the end-of-year rankings.
The silver medal is the least Fox should have got, and with a strong game on the sand-belt and a significant win in Queensland at the QLD PGA in 2018, challenging here should be a formality.
Fox has always had a strong driving game, and finding greens has rarely been an issue. However, he’s now gone from being one of the worst with the flat stick to ranking in the top-10 for putting average at even the toughest of courses.
I have the selection at the same price as Min Woo, who may have needed the run-out when a beaten 6/1 favourite here 11 months ago, so that 14/1 is simply too big to resist, especially as the latter has not won since July last year.
Fox can continue a big year for the Kiwis following Lydia Ko’s brilliant victory and subsequent crowning as this season’s LPGA queen.
The only other wager that appeals as a value pick is defending champion Jediah Morgan over Marc Leishman in a match bet.
Leish is a bit of a hero of mine, but it may sadly be time to give up on him as a serious potential winner in this class.
After a lucrative career, the 39-year-old came off a Covid slump to once again show up at Augusta over the last couple of years, but this has been a poor year.
There have been highlights – top-15 at the U.S Open, maybe – but he played poorly at River Highlands, in an event at which he historically does very well, and followed that with missed cuts at the Scottish Open and Open Championships, and midfield, don’t-write-home-about-it efforts at the first two FedEX play-off events.
Leishman is now at LIV, doing nicely ‘thank you’ and collecting $3 million for doing nothing much. In fact, his individual results gained him less ‘sole’ money than Pat Perez, another who caught onto the coat-tails of his teammates.
Respect to him, but Leishman isn’t going forwards these days, and will need the weather to turn bad if he is going to be able to live with some of these birdie machines.
Count Jediah Morgan as one of those birdie machines.
Although he produced a 100-1 shock in January when winning this event in just his fourth event as a professional, Morgan did it in some style.
The 22-year-old recorded three rounds of 65/63/65 to take a nine shot lead into Sunday, and simply went further clear, crossing the line 11 shots clear of Andrew Dodt, himself with plenty of previous in this grade at home, and a further shot clear of Min Woo.
In 2020 Morgan had won the Australian Amateur around this course, beating Tom McKibbin (see Joburg preview for his chances over there) by 5 & 3, an event that has thrown up Cam Smith amongst other multiple international winners, and whilst he hasn’t shown his best lately, returning to a venue he knows so well should be to his big advantage.
Morgan was one of the surprise signings to LIV Golf, although, as he admits, he “didn’t have much in my schedule,” given his exemption to the DP World Tour didn’t kick in till the 2023 season, plus it gave him the chance to compete at Centurion Club for LIV London – “The field is nice and strong so it’s a cool format to see how I shape up.”
Morgan has played every event since, although mixing it up with sporadic entries and invites onto the PGA, DP and Asian tours do not help a young golfer settle.
His Dunhill Links effort wasn’t bad – a 76 on that horrendous day two the cause of his eventual missed cut – but 25th and 13th at the last two events are as good as Leishman produced at the same events.
Leish has the back-form and the class but looks on the way down, and while the attention of being defending champ could overawe the younger man, he has put up with ‘Golf, but louder’ for a few months now.
I have these much closer than the prices suggest, so take the 8/5 in a match.
- Ryan Fox 14/1 Each -Way
- Jediah Morgan to beat Marc Leishman -72 holes – 8/5
TourPutt – The secret of the pros?
Driver vs. Putter: Your Choice?
If you were granted one golf-related superpower, which would you choose? The ability to hit 300-yard drives straight down the fairway all the time, or never 3-putt again?
Bobby Locke, one of the greatest putters in the game, said to ‘drive for show, but putt for dough’ And when you consider that the putter is the most used club in the bag, it seems like a no-brainer. But then again, according to Mark Brodie and his ‘strokes gained’ method, a long, straight driver may be more important to saving strokes. So what would you choose?
For me, I wouldn’t hesitate to go with the putting skills as I am currently suffering from the worst case of yips I’ve ever experienced in over 30 years. Sure, it’d be nice to outdrive the guys in my regular foursome, but I don’t think I can live down the shame of missing inside of 3ft all day, every day. And with no genie in site, I have searched high and low for that perfect putter that can cure my woes.
After trying nearly 50 putters over the past two years and enduring numerous snide remarks to get putting lessons instead, I finally gave in. I bit the bullet and sought professional help from Jong-hwan Choi, Korea’s number one putting coach to the pros.
Choi is an accomplished Tour putting coach who has made a name for himself through relentless research and dedication to master his chosen craft. Thus far, the pros and elite amateurs he helped have won a total of 350 tournaments, including KPGA, KLPGA, and LPGA wins. He is so popular that it can take up to a year to book a lesson with the man himself, but I was desperate. After pulling all the strings I can muster, I was able to get an interview with him in the hopes of getting some help
with my flat stick.
When the day finally came, I arrived at Choi’s academy armed with 3 of my current best-performing putters. I was eager to glean the secrets of the pros and to find out which of these best fit my stroke. I was greeted by Choi and briefly shown around the spacious academy, which had a large flat putting surface and some basic training aids that are common online. Upon chatting about Choi’s background and teaching philosophy, he reminded me of the motivational speaker Tony Robbins. He was constantly emphasizing positivity and proactive learning reinforced with hard work and dedication towards self-growth – that skills are built, not born. Sure, I get that.
But surely, preaching alone doesn’t improve (my) putting?
TourPutt: The Secret of the Pros?
When Choi offered (after some subtle arm twisting) to look at my putting, I was puzzled when he pulled out a tablet rather than some kind of putting trainer. I figured maybe he was going to film me first, then point out some flaws on the monitor. Nope.
We were going high-tech for this one. We were joined by his friend and business partner Chan-ki Kim, a software engineer who co-developed TourPutt, a state-of-the-art putting training system.
According to the dynamic duo, TourPutt was developed to accurately assess a player’s putting tendencies, habits, and skills utilizing big data and A.I. Rather than second-guessing and trying to identify the faults, Tour Putt acts like an MRI machine that shows the doctor where to problem lies. Once the diagnosis is made, Choi would bring to bear his extensive experiences to cure the ailing putter. Sounded simple to me. But how would it know what my problem was?
As Choi’s fingers danced over the tablet in his hand, the TourPutt sprang into action and a small circle the size of a hole-cup appeared on the artificial putting surface. As I surveyed the circle of light beamed from a ceiling projector, Choi asked me a question I hadn’t considered before. ‘Which breaks are you most comfortable with on short putts? What are the odds that you make them?’ Taking my blank look as his cue, Choi proceeded to explain the process of mapping my putting pattern to gauge my stren gths and weaknesses.
To begin, I was directed to putt a golf ball into a hole from 36 random locations ranging from 3 to 6 ft. A ball tracking camera with two projectors mounted on the ceiling rendered various crisp, clear images onto the putting surface. Prior to start, I was informed that the putting surface was sloped 3% from top to bottom. So if you were to imagine a clock face, the 12 o’clock location would be a 3° downhill straight putt, while 6 o’clock would be a 3° uphill straight putt.
As I am right-handed, all putts from the left side of the 3 o’clock would be a hook like, and the left side a slice lie, all to varying degrees. When I asked why it was fixed at 3%, Kim explained that tour regulation greens don’t allow for more than a 3 degree slope within 6ft of the hole. Also, most amateur golfers had a difficult time detecting such a small amount of slope, and thereby misjudge the breaks to a higher score.
Knowing Where to Tap
After the pattern test began, it took me a little over 20 minutes to complete a total of 36 putts at random locations. I was quite conscious of the many eyes on my performance and equally frustrated at how often I was missing putts despite my best efforts. After I was done, Choi pulled up my results, or key performing index (KPI), on a large screen TV where I was able to see exactly where I was effective in my short putts. In brief, I had a tough time with both hook and slice lie putts. I showed slightly better results with uphill straight and slice putts, but absolutely nothing to write home about.
Now, I’m sure many of you are familiar with the story of the plumber who was called to fix a steam pipe. After looking around the pipes and tapping a couple of valves, he charged $200 for his services. When the irate customer demanded to know why it cost so much and asked for a detailed breakdown of the services, the plumber replied, ‘$10 for tapping, $190 for knowing precisely where to tap.’
As such, my results from the pattern test were eye-opening. I’ve never known what lie I was more effective at, much less the percentage of probable success. For example, the more often I use TourPutt to practice or diagnose my putting, the more accurately it can diagnose my skills. Thus, I can pinpoint which area to improve through practice, as well as try to get the ball to an area I am more likely to save par.
Wow. This was tour pro stuff. Was this the secret of the pros?
I was starting to get heady with the possibilities this digital marvel was able to provide. It took both of them to bring me down to earth again by informing me that knowing the areas of improvement is only half the battle.
For the actual tapping part, Choi and Kim then walked me through the many innovative features of TourPutt focused on helping me improve my putting. I was mesmerized by the detailed graphics that flashed all over the putting surface.
I was already impressed with the diagnostic aspects of TourPutt, but upon seeing the actual features to help me improve my putting, I was doubly blown away. From reading the green speed and breaks accurately to effective swing tempo and motion tracking, the system seemed straight out of the future.
Before TourPutt came into being, Choi was frustrated with the difficulty in collecting crucial data from an actual green as it was difficult to find a flat area to map his student’s patterns. When he discussed the matter with Kim back in 2019, Kim immediately became interested in ways to mesh modern technology and A.I. driven data to the art of putting. As an elite level golfer with extensive knowledge in the fields of VR and AR (virtual and augmented reality), Kim understood right away the issues faced by Choi and how he could help.
Delving deep into Choi’s experience and insights, Kim designed the TourPutt’s interface to yield accurate and reliable data that can be cross-checked, correlated, and compared across past and future performances. Best of all, TourPutt and its proprietary app feature the ability to keep track of all of my performance from any TourPutt system and access the data anywhere at any time. I could even replay all of my past putts and see the speed and the path it took, and compare them with other golfer’s data in the system. Mind. Blown.
Kim further explained that this feature of collecting real-world significant big data is one of the biggest advantages of TourPutt, and enables it to evolve further with every putt stored in its vast database.
The Student Becomes The Teacher
Once the flaws are identified, we moved on to the more traditional slow-motion video to see what I was doing wrong to miss the putts. For me, I kept too much weight on the back foot, and also needed more forward press to keep the putter head online through impact.
After several minutes of drill to correct the issues, I was holing the putts much better. The data from the second pattern test confirmed the improvement, and I was also shown the actual paths that my two putts took before and after the fix. All in all, being able to verify that the diagnosis was correct with immediate results, all backed by data was highly reassuring and enlightening. But what if these improvements were short-lived? That as soon as I walk out of Choi's presence, the magic evaporates and my crappy putting returns? I can’t tell you how often a club I thought was the answer to my prayers devolved into an ordinary stick as soon as I paid for it. It’s downright uncanny how often this happens.
To this end, Choi gave me a glimpse of hope. He assured me that since I was investing time into my skills and not money into more equipment, it will definitely last longer. Also, the coaching provided by Choi is reflected in each and every putt I had made since the lesson and recorded as part of my putting profile. So if I were to stray from the ‘good’ putts, the system can be used to bring me back on track. And if this cycle of improvement continues, I would be able to be my own teacher and
eventually practice effectively and independently on my own.
Honestly, I don’t know about this part. After all, I too know that the right diet and exercise will give me a six-pack; but knowing and doing it are two separate things. In the end, how effective any tool can depend on how well I make use of it, so it will have to remain to be seen. What I can say with certainty, however, is that TourPutt seems to work for a lot of people. Choi’s students continue to post wins on various tours with regularity, each crediting him with their improved putting performance. In turn, Choi credits his partner Kim and TourPutt’s growing database for accurate diagnosis and self-learning.
In Korea, the art of putting has found its poster child in Choi, with more and more golf academies and private studios installing TourPutt for its members. Several local tour pros and top amateurs have also installed the not-so-cheap system in their homes and have said to benefit from the move. Remember when Tiger showed up one day at the range with his own Trackman? I would imagine having a TourPutt in your basement is something like that, but I can only guess. I don’t have a personal Trackman either.
Now that I know where I need to improve on, does this mean I will be taking money off my foursome buddies with alarming regularity? Well, let me see. I signed up for pilates a few months ago and found out exactly where I need to work on for more flexibility. But as I still creak all over when bending over to tie my shoes, I’d guess my putting won’t miraculously improve right away neither. But hey, that’s on me. I’ll just have to start working on the tapping part. Anyone looking to buy some used putters?
