Pros: FLT shafts use a flighted design, which helps golfers launch their long irons higher and with more spin. The FLT short-iron shafts provide a more penetrating trajectory for more control.
Cons: FLT shaft flexes correspond with weight, so golfers may not be able to match their desired shaft weight with their desired flex.
Who They’re For: Golfers who need more spin or more launch from their long irons to optimize their trajectory. Everyone from beginners to PGA Tour players can use the shafts effectively, but they’ll be most popular with golfers with moderate-to-slow swing speeds, or any golfer who generates low-spin launch conditions.
Selecting the proper iron shafts is one of the most important equipment decisions golfers make. It’s an issue of quantity. Most golfers carry about 7-8 irons in their bag, so if they choose the wrong iron shaft, they’ve made the game harder than it needs to be with half or more of their clubs.
The good news is that there’s a wider selection of quality iron shafts than there has ever been, with recent growth in models that are designed to help golfers hit their iron shots higher and farther, while still maintaining PGA Tour-quality consistency and feel.
KBS is one of the leading steel shaft manufacturers, and already offered a wide variety of models prior to its newest shaft launch. Company representatives felt KBS was lacking a product for a particular segment of golfers, however, so it developed its new FLT shafts.
FLT shafts ($31.95 each) have a flighted design, which helps certain golfers optimize the performance of each iron their bag. The long irons shafts have progressively softer tip sections, which helps golfers increase their launch angle and spin rates with those clubs. For the right golfer, the design will help them hit their iron shots farther, and stop shots on the green more quickly. In the short irons, where height and spin are easier for golfers to generate, the FLT shafts are stiffer, which creates the flatter trajectory most golfers prefer with their scoring clubs. The crossover point between the higher-launching long irons and lower-launching short irons is the 7 iron.
Like all KBS shafts, FLT models have a constant weight, which means that long iron shafts and short iron shafts will be roughly the same weight through the set. Shaft weight is dependent on flex, however, as softer-flex models are lighter than stiffer-flex models. So if you’re looking for a really heavy, regular-flex shaft or a really light, extra-stiff-flex shaft, these aren’t for you.
Keep in mind that KBS shafts do not have reinforced tip sections like many other iron shafts, which gives them a slightly higher balance point and can decrease swing weight by 1-2 points. I personally like the feel of KBS shafts and their slightly higher balance point, but some golfers won’t.
For this review, I tested the new FLT shafts head to head against KBS Tour shafts of the same flex and weight (130X) in 4 irons, 6 irons and pitching wedges. Each of the shafts were installed in Callaway’s Apex Pro ’16 irons, and were built to my specifications (standard grips, standard length, 1-degree strong lofts, 1-degree flat lie angles).
I performed my testing at the Launch Pad at Carl’s Golfland in Bloomfield Hills, Mich., where I hit the 4 irons, 6 irons and pitching wedges on Trackman IV with premium golf balls. I hit 3-6 solid shots with each iron, and then removed the outliers from the final data in an attempt to compare only the most similar strikes. Results were normalized.
As you can see from the data, there was a significant difference in the flight of the 4 irons with the two different shafts, but less of a difference with the 6 irons and pitching wedges.
As expected, the FLT shafts caused 4 iron shots to launch higher (0.8 degrees) and with more spin (729 rpm) than the KBS Tour shafts. I’m not a low-spin player, which is one of the target audiences for this shaft, so the added launch and spin of the FLT shafts caused my 4 iron shots to fly shorter. Golfers who launch their irons too low or with too little spin, however, will likely see a distance increase when using the FLT shafts.
As I moved closer to the short end of the set, the two shafts started to perform more similarly. Theoretically, the 6 iron shots with the FLT shafts should have launched slightly higher and spun more than 6 iron shots with the KBS Tour shafts, but I actually saw a slightly lower launch angle (0.5 degrees) with the FLT. The spin was higher, though, by 211 rpm. With the pitching wedges, the results were again quite similar. The FLT launched 0.9 degrees higher, but actually spun 271 rpm less than the KBS Tour shafts.
Stepping back from the numbers, I was impressed with how similar the feel was between the KBS Tour and FLT shafts. Yes, I could feel that the FLT shafts were more active in the tip with the 4 irons, but they felt nearly the same in the 6 irons. By the time I got to the pitching wedges, the two shafts were indistinguishable. The KBS Tour is considered one of the better-feeling iron shafts currently available, so KBS’ ability to replicate that feel in the FLT will be a plus for the majority of interested golfers.
Looking more broadly, trends in shaft design tends to go hand-in-hand with trends in club head design, and the FLT shafts are no exception. Equipment manufacturers continue to strengthen the lofts of their distance irons; they have to in order balance the launch equation, as their faster ball speeds create a higher launch angle and more spin.
While the improvements to iron design have allowed golfers to hit their mid and short irons farther, many golfers continue to struggle to hit their long irons high enough or consistently enough for them to be effective. And based on my testing results, it’s clear that the FLT shafts can make long irons more playable for certain golfers, and maybe even keep long irons in a golfer’s bag that might otherwise be kicked out for higher-flying hybrids or fairway woods.
As always, I recommend that golfers get properly fit for iron shafts, which means visiting a reputable club fitter in your area. So if you’re in the market for new irons or iron shafts, you can get started by going through KBS’ Online Fit System, which upon completion lists KBS-certified dealers in your area.
GolfWRX Spotlight: Tour Edge Exotics EXS Pro hybrid
Hybrids, for many of us, are one of the clubs that don’t get replaced very often. Once we find one that we can confidently hit in pressure situations, it stays in the bag for as long as possible.
I am exactly one of those players as my hybrid has been in the bag since 2015 and has the paint chips and embedded dirt to prove it. That club has been my crutch to lean on when I couldn’t hit anything else straight off the tee, needed to hit the green on a long par 3, or go for the green in two on a par 5.
I wasn’t really looking for a new one when the Exotics EXS Pro showed up at my door, but the shape grabbed my attention, and I had to give it a try.
Tour Edge just announced the Exotics EXS Pro line of woods and they are “from the tour van” with tour-inspired shapes and performance. You can read the whole launch story we did HERE and also read about the new fairway woods.
The EXS Pro hybrid is smaller and has a deeper face than its EXS 220 sibling, giving it a look that better players look for. The shape is initially what got me, as it isn’t a tiny hybrid like we have seen with some other “tour” versions, but it isn’t too large either. The head is also a little more rounded overall, without a sharp toe or other lines. As I am one to hit my hybrid off the tee a good amount, the deep face was welcome—while it isn’t so deep that you can’t hit it off a tight fairway lie. The moveable weights in the sole allow you to adjust the head in order to make it an “anti-left” club that many better players fear.
On the course, I really felt comfortable with the EXS Pro right away. The first shot came off the face feeling hot thanks to the Beta Ti Face that is brazed onto the stainless steel body. The ball speed is really fast and the shot shape was flatter than my previous hybrid setup. If you are a high ball hitter and have a hard time with hybrids, the EXS Pro should be on your shortlist of new ones to try. Better players are going to love being able to flight the ball for windy conditions. Distance is of course fantastic, but it is repeatable and consistent.
The EXS Pro is a little longer than my previous hybrid, but still fitting into the distance that I require. Tour Edge didn’t just make the club longer to add distance, the lofts are pretty standard as the 19-degree I have is only 40.25” long and has a lie angle of 57.25 degrees. Dialing in the EXS Pro should be no problem since they make six lofts between 16 to 22 degrees to fit your gapping needs.
Over the past two weeks, I have found that this EXS Pro does remove the left side of the course. Tour Edge claims it is an anti-left hybrid, and so far I have found that to be nothing short of the truth. Shots are slightly fade biased with the heavier weight in the toe, but you can still easily turn it over and hit it straight. Tight lies or fairly deep rough are no problem with the compact shape and Slipstream sole, making it versatile all over the course. I
like the deeper face for hitting if off the tee and shots where the ball is sitting up in the rough. That deep face just gives me a little more confidence that if I get a little steep with my swing I will still be able to save a decent shot.
My only real complaint is that the EXS Pro’s Slipstream sole collects some dirt, and you have to grab a tee to clean it out, but really nothing that should stop anyone from putting this in their bag.
Overall The Tour Edge Exotics EXS Pro is an anti-left hybrid that is built for better players. What is might not have in total forgiveness it makes up for in lower launch, great distance, and its fade bias. If you have been struggling to find a hybrid to fit your game, the Tour Edge Exotics EXS Pro could be your answer.
GolfWRX Spotlight: Crossrope weighted jump rope & app
An 18-hole round of golf averages out to just under five miles of walking, which on its own is a good workout. Once you throw in some potential uphill trekking you get some serious cardio too, but if you all looking for a quick workout between rounds of golf look no further than Crossrope.
Crossrope – The details
Crossrope is a system of the weighted jump rope that allows you to quickly switch the weight of the ropes you are using to boost your workout—they range from 1/4 lbs all the way up to 2 lbs depending on the kit you start out with. There is an accompanying app that helps you go through multiple workout routines and is available free, or you can upgrade to the entire library of workout routines along with more workout tracking options.
This is NOT your middle school jump rope
The handles are heavy duty and feature precision bearings to allow the rope to move smoothly around as you go through a routine. They are also ergonomic and fit into your hand naturally, which making gripping easy, something that is really nice when you’re swinging a 2 lbs coated steel cable around. The handles also come with a fast clip system to make changing cables depending on your selected workout easier too.
The ropes themselves are made from braided steel and are almost impossible to tangle, allowing them to be easily transported and stored when not in use. All in you are getting a premium piece of workout equipment that is effective and easy to store—hard to same the same thing about a treadmill.
When it comes to a workout, skipping rope is one of the most effective cardio workouts you can do, and with Crossrope, you can get both cardio and low impact weight training when using the heaviest ropes, and follow along with the guided workouts.
As someone that hadn’t used a jump rope in over a decade, starting out lighter was a nice way to ease in before moving up, and I was pleasantly surprised how easy and fun some of the workouts in the app were. If you are looking for a fun way to add something to your workouts, or you just want to try something new to get you into golf course walking shape, this could be right up your alley.

TaylorMade SIM and SIM Max driver review
New for 2020, TaylorMade has launched the new SIM driver family. First the lower spinning SIM then a more forgiving higher spinning SIM Max and a SIM Max D head to help draw the ball for those that need it.
We have seen the tour players using all three of the SIM drivers.
- Keegan Bradley WITB using the SIM Max D
- Tiger Woods WITB using the SIM
- Dustin Johnson WITB using the SIM Max
The SIM, SIM Max, and SIM Max D drivers from TaylorMade feature an asymmetric sole shape as well as a redesigned Inertia Generator. The asymmetric sole shape of the drivers is designed to reduce drag while providing faster clubhead speed, with the redesigned Inertia Generator redistributing weight at the very low-and-back portion of the club in a bid to provide improved forgiveness.
The SIM Max D clubhead contains a heel-bias internal weight with a topline masking to make the clubhead look more open at address to help golfers who struggle with a right-miss.
Other features of the SIM, SIM Max, and SIM Max D drivers includes a speed injected twist face, inverted cone technology, a thru-slot speed pocket, multi-material construction and an adjustable loft sleeve.
Exclusive to the SIM driver is sliding weight technology which allows face angle and flight bias preferences of up to +/-2° loft change and up to +/-20 yards of draw-fade bias.
Here are the individual reviews from GolfWRXers’ trip to The Kingdom.
Tester: Rob “osubuckeyes691“
I’ll start by saying this. SIM is very good. It’s not a magical 30 yards like everyone is talking about here. That comes from being properly fit. But it is good, and with a proper fitting I’d be shocked if you couldn’t find at least slightly better numbers with SIM over any gamer you have.
My current set up is a Callaway Epic Flash SZ Double Diamond with a Fuji Ventus Black 6x. LOW LOW LOW combo…and I still hit it high haha. I live in the low to mid 170s ball speed with spin sometimes getting up to 2700 2800. Drives I hit well, spin around 2100. My miss is a big push slice.
But it is good, and with a proper fitting I’d be shocked if you couldn’t find at least slightly better numbers with SIM over any gamer you have. -Rob
I ended up being fit in to a SIM 9* with the new KBS Tour Driven 70 Category 5. This shaft is super interesting. It’s really hard for me to describe but it has feel, and a lot of it. Spin dropped to about 2400 on my miss right and really, that’s what I was hoping would happen. I wanted something that when I missed, wouldn’t lose me 30 yards. We put the weight in the heel and it really did help straighten out the miss. Huge advantage for me. I knew as someone who swings 120ish I wasn’t going to pick up 20 yards. I wanted to reduce my miss and that’s exactly what SIM was able to do for me. Here is a link to his post in the forums.
Tester: Will “fillwelix“
For my driver fitting, I was with Perry, who was a blast to get to work with. I started by hitting my gamer on Trackman, talking with Perry about what my misses usually are, and what I wanted to get out of the fitting.
I usually don’t have a problem with distance so I told him the biggest thing I was looking for was a tighter dispersion. I don’t have the trackman numbers yet but with my gamer, I was averaging about 110 club head speed, 160-something ball speed, 270-275 carry, 285-290 total. Launching a bit too high but spin was okay.
The thing was seriously nuclear. My club head speed bumped up only about 1 or 2 MPH, but the launch and spin were incredible, as well as ball speed. I topped out at 170 ball speed, which I had never gotten before. -Will
We tried the 10.5 SIM in a Ventus Black 6x, and he gave me a couple tips in my setup, because my AOA was something like 4 or 5 degrees up. The thing was seriously nuclear. My club head speed bumped up only about 1 or 2 MPH, but the launch and spin were incredible, as well as ball speed. I topped out at 170 ball speed, which I had never gotten before. Carrying 295-300, total of 315-320. One shot carried the fence of the driving range at The Kingdom.
Spent some time going through different shafts to see if there was an improvement, played with weights, etc. but the best numbers were with the 10.5 SIM with Ventus Black 6x and the weight all the way in the toe, because my miss is usually left. Here is a link to his post in the forums.
Tester: Nick “n_rones“
I started off with my fittings working with Joe. After some warmup we started with the drivers. Coming in I was playing a Srixon Z785 with a Hzrdus black 6.5 70 gram shaft at 45 inches.
I’m a really tough fit because I have an unusual swing and hit down on the ball heavily with every club. My AOA with the driver was between 5 and 7 down which is pretty nuts I always knew I hit down on it but not that much. I’m still waiting on the trackman date to be emailed to me but with my own driver I was somewhere in the neighborhood of 109 swing speed with a launch angle of 4 degrees and 4000 spin (Ridiculous I know right).
I was able to take it on the course with me that afternoon and hit 12-14 fairways a new record for me and ever ball was easily 15-20 yards longer than I was used to. -Nick
His main goal for me was to get launch up and spin down. The first club he handed me was the Sim 10.5 turned up to 11.25 with a Graphite design IZ 7x. Instantly my launch angle increased and spin dropped. We then went through a few other shafts like graphite design ad di 7x. We came back to the IZ and with a quick change in tee height we ended up where we wanted. We knew with my angle of attack we were never going to get me to super low spin and high launch we just wanted to get it to a manageable number.
By the end of the fit I was hitting the sim with the iz under 3k spin with a couple down at 2500 and 9 degree launch increasing my carry from the 244 range up to the 260-265 range on good swings and we neutralized my cut massively. I was fortunate enough to finish my fit while other guys were still busy so we went right into the build shop and he built me my driver on the spot and gave me a super cool kingdom exclusive headcover. I was able to take it on the course with me that afternoon and hit 12-14 fairways a new record for me and ever ball was easily 15-20 yards longer than I was used to. Most of that is me never being through a proper fitting before but a big factor was I was able to get into the sim head with high loft but it was a great spin killing head for me. Here is a link to his post in the forums.
I am one that gained a good bit of ball speed from getting fit for the SIM driver. My gamer is a Titleist 915D3 9.5* with a Rogue Silver 70X. I wasn’t fit for the driver as I just bought the parts off of the BST. I always felt that I lost yardage due to high spin. The Trackman didn’t lie as I was getting 166mph ball speed and 3000 rpm of spin on well-struck shots. Where this posed a problem was when I was off-center, the ball would be a high right spinner that would lose a lot of distance.
Where I saw great gains was in dispersion. TwistFace just flat out works. Toe shots came back to closer to center, and heal shots faded right back towards center. I also didn’t lose as much yardage. I did pick up about five mph in ball speed. There are a plethora of reasons for this gain and the resulting 20 yard gain in ball flight.
Some could attribute the gain to almost 30 feet of height in ball flight. It could also be because there was 300 less RPM, or over a degree increase in launch angle. Either way, it has proven to me that getting fit by a knowledgeable fitter is crucial. This is the first time that I have been fit for a driver. All the expectations of mine going into this fitting have been met.
The SIM is forgiving. The SIM is aerodynamically superior to what I have been playing. The SIM just flat out performs for me because it doesn’t balloon, it is forgiving on mishits with good direction and ball speed, and it reduced my spin rate. –
The sounds of the SIM line is amazing. The solid “thwack” sound it makes at contact is extremely welcoming. Gone are the days of high pitched aluminum baseball bat sounds. Now, some sounds just sound perfect to me. Johnny Wunder posted a video on Instagram of me hitting a driver, and you can hear the sound. Here is a link to his post in the forums.
