Review: KBS Tour FLT Shafts

Published

on

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.

Overview

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.

FLT Specs

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.

The Test

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).

KBSTour130Shafts

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.

Apex_Pro_Test_heads

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.

Takeaways

KBS_Tour_KBS_FLT

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.

      How is it a joke? Seems logical….updated version of the old rifle flighted…..instead of decending weight it’s constant weight. With KBS signature feel a stability and step pattern…And I’m sure the bent tip jokes will be coming at some point. But I’ve enjoyed the set I have especially with my PXG irons.

        Look at the real life numbers for the 6 iron and pw.6 iron was meant to go higher and pw lower but both didnt.
        Thats why its a joke.

          From the description it’s designed for people who have issues launching the ball with longer irons and lower with the shorter irons. Obviously the writer isn’t the target audience and stated that. So your ignorance is the joke and why it’s important to get fit. Instead of being a know it all like yourself.

Ari’s Course Reviews: Riviera Country Club

Published

on

Riviera Country Club was designed by George Thomas and opened in 1927. Construction was done by Thomas’ right hand man, Billy Bell, whom he worked with on all of his great projects in California. Instantly regarded as a top test of golf, Riviera Country Club has hosted 3 major championships. When the pros tee it up this week at Riviera for the Genesis Open (formerly the Los Angeles Open), it will be the 55th time the course has played host to this now annual test of the best in the world.

The clubhouse is one of the most amazing in golf; it sits up on top of a hill with the golf course (other than the first tee and 18th fairway/green) laid out in the lower canyon, continuously bisected by a set of barrancas that are integral to the strategy of the course. The first tee is right next to the pro shop and is one of the most unique and best in all of golf. Literally feet away from the pro shop and the starter shack, each player gets their name and home town announced as they prepare to tee off, an experience that gives the place an even more special feel. Sometimes it’s the little details that matter. The first tee shot drops 75 feet to the fairway, giving you the feel of standing on the edge of a cliff as you tee off on the first hole.

George Thomas was all about strategy and angles in his course design. It was a constant theme in the courses he designed, as well as the books he wrote. This can be seen in most of the holes at Riviera. The best angle into the green is almost always the angle off the tee with the most trouble. You can see this on holes 1, 2, 3, 7, 9, 10, 13, 17 and 18. If you challenge the fairway bunker, or barranca, or stay tight to the tree line, you get a much more open angle into the green. If you play out to the open side of the fairway, you have a much more difficult shot into the green.

The view of the first tee, and first fairway down below

There are only two or three par 5s on the course, depending on if you’re talking about member play or the PGA Tour. The first hole is just a shade over 500 yards and sometimes plays as a par 4 for the Tour. After the extremely memorable drop-shot tee shot, you descend into the valley that most of the course occupies. A barranca crosses the fairway at about 300 yards. The green is wide and wraps around a deep centering bunker.  There is a deep fairway bunker on the left side of the fairway past the barranca that does not really come into play for the Tour, but for the members if you can challenge this bunker you generally get a better angle into the green, unless the hole is cut on the far right side of the green. The 11th hole is tight between two stands of trees and crosses another barranca on the way to the green with a deep bunker guarding the right side. The 17th is a long, challenging, uphill par-5. The fairway is heavily bunkered on the left side. The right side is up tight to the tree line with only a single bunker back in the fairway. The green is large and double tiered. It is open on the left and guarded by and extremely deep bunker on the right. The best angle into the green is as close to the fairway bunkers on the left as possible.

Riviera has a great set of par 3s. The 4th hole was called the greatest par 3 in America by Ben Hogan, and it’s a long, Redan-style hole with a huge bunker short of the right-to-left sloping green. A shot out to the right with a draw can catch the contours on the right side and send the ball close to the hole just as easily as a high spinny shot right at the hole. The 6th is a true Thomas original and one of the most unique holes in the world. It’s a mid-to-long iron uphill to a large green with a bunker in the middle. The genius in this green is that it is contoured in such a way that you can get the ball close to the hole from just about any spot on the green to just about any hole location. The 14th is a mid-to-long iron to an elevated green that is wider than deep, and fronted by deep bunkers. The 16th is a gem of a shot hole, just 166 yards from the tournament tee to a very tiny, almost island of a green surrounded by sand. Besides being tiny, the green is fantastically contoured for its size and seems to fold up on itself. Hit the green and have a great chance to make birdie… miss into one of the deep green side bunkers and good luck making par!

The par 4s are nicely varied in length and challenge. Hole No. 2 is very difficult and plays uphill to a green banked into a hill that is long and skinny. Challenge the fairway bunker on the right for the better, open angle into the green.  Hole No. 3 plays slightly downhill to a fantastic fallaway green. Challenge the fairway bunker on the left for the better more open angle into the green. Hole No. 5 is a standout hole with a semi-blind tee shot that bends softly to the left around the edge of the property. Its unique feature is a large grass mound that extends out into the fairway short and right of the large back to front sloping green.  Hole No. 7 is a very tight driving hole; the fairway is tightened severely at about 275 yards by a huge, winding bunker that cuts in from the left side. The more you challenge this severe hazard, the better your angle into this very narrow green protected by a barranca and deep bunker on the right. The left is a bailout area cut as fairway, but the slope up to the green is steep and the up-and-down from there is not an easy one.

The 8th hole starts one of the most interesting 3-hole stretches in PGA Tour golf. It’s a split fairway par-4 with two distinct fairway sections that are bisected by a deep barranca. Depending on the hole location and ones preferred shot shape, and what fits the eye, the hole can be played any number of different ways. In general, the left fairway is a little more demanding to hit, but sets up better to most hole locations. The right fairway is a little more accessible, but leaves a more demanding shot into the green. This was one of George Thomas most famous holes and the right fairway was originally washed away in 1938. It was brought back in play around the recent turn of the century, and, while not an exact replica of what was there, provides the strategic design that Thomas intended when he designed the hole.

The 9th is one of the most difficult holes on the course and plays uphill to a deep, narrow green that falls hard from back-to-front. The tee shot is pinched by a pair of bunkers, but in true Thomas strategic fashion, they are staggered by about 55 yards so the player can plot their best line and try to execute on their strategy.

An aerial view of the 10th hole

The 10th is simply one of the best holes in golf. An absolute masterpiece of a short par 4… maybe the best short par 4 in golf. The player is presented with a multitude of options off the tee. The easiest shot off the tee again yields the toughest shot into the green. A mid-iron just short of the cross bunkers carries very little risk, however, the player is then left with an extremely difficult short-iron shot into this tiny sliver of a green from absolutely the worst angle. The safest way to play this hole is to take this route from the tee and then hit your second shot short left of the green. This will give you a chance to get up-and-down for par from the best place, but intentionally missing a green on a par 4 that is barely over 300 yards is not a choice most are willing to make. The next safest option off the tee is a long iron or fairway wood down the left side towards the far left fairway bunker. This leaves a shorter shot into the green from a much better angle. Then there is also the play of hitting driver between the bunkers right at the green. Pull this off and leave yourself the best chance for par or birdie, but miss the tee shot at your peril. There are a lot of big numbers waiting on this hole for the aggressive player. The green is extremely narrow and slants hard from right-to-left. It is extremely difficult to hit from any distance. This is a hole that has perplexed the best players in the world for 90 years and has been studied by anyone that is interested in golf course architecture. Truly deserving of its reputation as one of the best in the world.

Hole Nos. 12 and 13 play along the edge of the hill that defines the property line across the valley from the clubhouse. A line of Pacific Palisades mansions look down on these holes as the land slopes gently towards the ocean. Hole No. 12 bends to the right and crosses the barranca, while 13 bends left and is tight and is lined with trees. Hole No. 15 is a hard dogleg right with a deep bunker guarding the inside of the dogleg. Play out to the safe left side and the hole plays longer but more open. Fly the fairway bunker and get into the fairway and shave some yardage off the hole. The green is huge, bisected by a large swale, and is my personal favorite on the course. The 18th is one of the most difficult and famous finishing holes in the game. A long, uphill par 4 with a blind tee shot over a hill that bends gently to the right along the tree covered hillside.  The closer to the tree line on the right you find your ball, the better angle you get into the small green that is set into a natural amphitheater in the shadow of the clubhouse.

A view from behind the 18th green

Aside from a great collection of holes, Riviera is one of those courses that is more than the sum of its parts. The routing is tight and extremely walkable, and the greens and tees are all in very close proximity to each other. Other than walking down the big hill off the first tee, and up the big hill after 18 tee, the course meanders up and over some nice rolling terrain, but there are no strenuous walks. The bunkering is stunning and fits the sense of place that you get from the course and the site well. They give the feeling that every square inch was sculpted perfectly as intended. They have lips that are built up and over which makes them extremely deep and difficult.

The site is fantastic too, ringed by mansions of the rich and famous up on the hillside and laid out mostly in the canyon below that cascades gently towards the ocean. The barrancas that run through the property are used strategically over and over again by Thomas and they add immensely to the character of the course. Unfortunately, George Thomas did not design that many courses and equally tragic even less of them are in existence today. Fortunately, Riviera is still there today, so George Thomas can still show us how much fun a course full of strategy, beauty and challenge can be.

A day at Riviera is a very special one and this is one of the PGA Tour events I most look forward to watching every year.

On the course? Off the course? Adidas’ new adicross line has you covered

Published

on

Furthering golfwear’s trend toward the more casual and versatile in a big way, Adidas today unveiled a new line extension: Adicross.

Urban inspired. Decidedly non-traditional. The Adicross line (styled “adicross”) leverages Adidas’ clothing and footwear styles from other arenas and reimagines them for wear on the fairway. Available December 1, the line brings Anorak jackets, henleys, hoodies, joggers, and even an Oxford to the golf course.

And before you clutch your saddle shoes in terror, remember, this is a line extension targeting a particular segment of the golfing population, not a total change of course for the entire Adidas Golf brand. If you’re wondering who represents the segment in question, think Erik Anders Lang: filmmaker, irrepressible golf enthusiast, and host of Skratch TV’s Adventures in Golf.

Lang hosted a launch event in Manhattan’s Meatpacking District warehouse space where he sat down with Adidas execs and world No. 1 Dustin Johnson for a chat about the new line. He praised the performance aspects of the five-pocket pant and the footwear styles, in particular.

As for golf’s top-ranked player, regarding the Adicross line, DJ told us the line is much more in keeping with stuff he’d actually wear than the baggy shirts and khakis that were the uniform of golf when he started out on tour.

“This is a line that I’ll wear all the time,” Johnson said. “I can wear it to the course and then go meet some buddies for lunch, and I’m not a walking poster for golf.”

From the Stretch-Woven Oxford, to the jogger pant, to the Adicross Bounce footwear, every item Dustin Johnson wears in picture below is intended for both on- and off-course wear.

“Adicross is the lifestyle brand that golfers everywhere have been waiting for,” said the world No. 1. “This is something that I’ll wear when I’m traveling to a tournament, practicing at home, or even headed to the gym.”

The aforementioned versatility of the Adicross line is very much a function of the materials: No-show sweat wicking technology, nylon-spandex blends (featured in the five-pocket pant and short), Primeknit (featured in Icon Polo and Jacket). These are clothes that are ready to wear to the office, but stretch, are light enough, and offer enough comfort to play 18 holes in.

“We wanted to challenge ourselves to design a line that would aid in helping athletes in their game, their life and in their world,” said Chad Alasantro, senior designer, men’s apparel at adidas Golf. “adicross is a perfect blend of hidden technology, fused with a creative aesthetic.”

 

The Adicross line also boldly brings street-inspired footwear to the golf course, retooling Adidas’ ultrapopular Bounce design to support the foot and grip the turf during the golf swing (and resist water during dew-sweeping early morning rounds)

“Adicross was designed as a result of the feedback we were hearing from our core consumer,” said Dylan Moore, Creative Director, Adidas Golf. “Like everyone else, golfers live in a complex, busy world with many diverse interests. They expect more from less and demand performance out of what they wear.”

The centerpiece Bounce features an ergonomic fit, offset wrapped saddle with multiple eyelet rows for customizable lacing, and a non-marking adiwear rubber spikeless outsole that features 181 strategically-placed lugs for a green-friendly grip.

The Bounce will be released in January, and additional styles will follow in February.

Regarding said “additional styles,” you can spot a few in this promo video.
