The Wedge Guy: Some things that make me go “hmm…”

Published

on

As you might imagine, playing golf as long as I can remember–and then tacking onto that passion 40 years in the golf equipment industry–has given me a broad perspective on the evolution of golf clubs and the game we play. And those six decades of observation and experience have not yielded a shortage of things that make me scratch my head and just wonder…wonder why that is?

Of course, beginning golf in the 1950s and developing into a pretty good teenage golfer in the 1960s meant that I learned with persimmon woods and forged blade irons—that’s all there were back then. As I entered the golf industry in the late 1970s, I was blessed to do marketing work for Joe Powell, who was a total maestro when it came to crafting the finest persimmon woods. That was before the introduction of the TaylorMade metal woods, so everyone played persimmon. I learned a lot about golf club performance from Joe; for example, you wouldn’t know that he was frequency-sorting shafts before anyone was commercially offering “frequency matching.” Joe just saw it as a way to eliminate a variable in the golf club.

Over those 40 years in the golf equipment industry, I have observed the evolution of all our clubs from those earlier “states of the art.” No one then would have imagined the technology we now see in drivers, irons, putters, shafts…but all that technology leaves me scratching my head all too often; I would like to share just a few of those puzzling observations and get your take on them, OK?

What really makes today’s drivers so much longer?

It is impossible to isolate any single technology and how much it affects driving distance. Since those days of persimmon, we have had quantum leaps in shaft technology, heads have gotten nearly three times the size in volume, we have pushed perimeter weighting to the max, and we have faces of exotic metals that act like trampolines. While all of those things have contributed to the distance gains, as far as the driver is concerned, my take is that it mostly boils down to two primary things.

  1. Drivers are at least two–and up to three-plus ounces–lighter than they were back then; that’s a weight reduction of 15-25 percent, so of course, we can swing them faster…and clubhead speed makes the ball go further.
  2. We all swing harder than ever before because the penalty for an off-center hit has been reduced dramatically. In my opinion, all the other technologies only tweak the effect of these two advancements. What do you all think?

What is the deal with “matched sets” of irons?

From the advent of “matched sets” in the 1920s (a development pushed by Bobby Jones), irons have been designed so that the lowest-lofted 2-iron (now 3 or 4) through the highest loft club marked ‘P’ or ‘W’ all look alike. That’s always puzzled me because the impact dynamics of a 25-degree iron are radically different from those of a 45-degree iron.

Only recently have manufacturers begun to mildly modify the mass distribution through the set to give higher launch angles to the long irons and lower trajectories to the short irons, but when will they take this to the optimum and break the chains that bind–the restriction that all the irons in a set must look alike? [NOTE: I know that mixed sets have been offered and failed, so maybe it’s us golfers that won’t let them do that.]

About those adjustable drivers/fairways…

The advent of the adjustability device has completely taken over the driver category. There are very few sold today that are not adjustable, and there are a myriad of devices and principles espoused by the various manufacturers. But I’ve always been puzzled by one very important aspect of this. It would seem to me that to be truly “tweakable,” the driver shaft would have to perform in an identical fashion regardless of the position to which it has been rotated.

But we know that even the finest graphite shafts are not completely straight, completely round or completely symmetrical in flex performance. The fact is that, at 100-plus mph, the driver shaft is exhibiting a lot of split-second dynamics, and those can change depending on the orientation of the shaft into the clubhead. That’s why we have the concepts of “spine-ing” shafts and even more sophisticated “Pure-ing.” The problem is that we don’t know what we don’t know about any specific shaft. I’ll leave the rest of this conundrum to your own head-scratching.

Forged blade irons vs. mainstream wedges

Being a wedge junkie, this one puzzles me the most. Statistics indicate less than two percent of all golfers game a true single-piece forged blade iron (but a large percentage of tour players still favor them).

I’ve heard all the reasons…

“The thin top line is intimidating.”
“I can’t get the ball flight I need from the lower lofts.”
“I’m not good enough to play these.”
“They are not forgiving enough.”
“Blah. Blah. Blah.”

But yet 95 percent or more of all wedges sold are of the same design favored by the tour players. Single piece cast or forged designs…just like tour blade irons. Heavy and stiff steel shafts…just like tour blade irons. I can’t make sense of that, but with very few exceptions, that’s all the industry gives us, isn’t it?

Let me share a little secret that no one will tell you. On an “Iron Byron” swing robot, a tour blade 9-iron is much more forgiving of mishits than any of the current mainstream wedges.

Does that make any sense at all?

I think I might have just opened a can of worms, and we can spend lots of time talking about this, I’m sure. And we probably should. Please sound off with your comments on this first handful of topics, and let’s tackle some more.

What makes you go “hmm…”?

Terry Koehler is a fourth generation Texan, a native of a small South Texas town and a graduate of Texas A&M University. He has had a most interesting 40-year career in the golf industry. He has created five start-up companies, ranging from advertising agencies to golf equipment companies. You might remember Reid Lockhart, EIDOLON, SCOR, or his leadership of the reintroduction of Ben Hogan to the golf equipment industry in 2014. For almost 25 years, his wedge designs have stimulated other companies to slightly raise the CG and improve wedge performance. He has just announced the formation of Edison Golf Company and the new Edison Forged wedges, which have been robotically proven to significantly raise the bar for wedge performance. Terry serves as Chairman and Director of Innovation for Edison Golf, which can be seen at www.EdisonWedges.com. Terry has been a prolific equipment designer of over 100 putters and several irons, but many know Koehler as simply “The Wedge Guy”, as he authored over 700 articles on his blog by that name from 2003-2010.

    Terry

    The Iron Byron info related to single piece blades is telling.
    But i play the Ft Worth 15 and TH/SCOR wedges.
    So I agree with you

    Terry –

    In addition Rob’s comment above regarding momentum is true, and the fact that Cleveland Srixon makes their clubs heavier to increase swing MOI in many of their designs also helps create greater distance. In a regular cast cavity back the Z-355 irons are my longest to date and the 355 Driver the straightest. In other drivers I have I have added weight until my swing speed goes down – this gives me maximum momentum for my ability.

    Terry –
    Appreciate the article. Started to take golf seriously about 20 years ago at age 45. From the beginning I read and was told that I could not play forged irons, even though they looked and felt the best to me when demo-ing them at my local Golfsmith. I immediately began to try them all. The problem I found was not the head but finding such “better player” clubs with softer than usual flex shafts that worked for me was really difficult. So I got into club making and mixed and matched shafts that worked with various forged sets, and found I played just as well with those sets, and enjoyed the game more with forged clubs (cavity muscle backs mostly). Presently however I use forged clubs from the 6 or seven iron down – distance comes from hybrids now.

    But one of the biggest developments in club design for me was the implementation of the V-sole (TK invention) which I have on my collection of Cleveland /Srixon clubs (Cleveland CBX, Z-565, Z-765, and Z-355). I shoot my lowest scores with these and am convinced that it is because the way the v-sole interacts with the turf that keeps my clubbed speed up and along the target line. My success with these led me to purchase a set of used SCOR 4161 wedges (42, 47, 51, 55, 61) that have the first V-sole. Despite the small head I am amazed how these clubs always seem to be right on the pin, and go the distance I intend. And they weren’t even fitted to me. So I use the V-sole through my entire set and this design really works. Finally, at least with the scoring irons (6-wedge) my distance with cast cavity backs and forged clubs is virtually the same given the same loft. I am, most of the time on the center of the face.

    My most recent experiment is with hollow hybrid like irons with which I have not had success and never liked the feel, sound or turf interaction until I discovered the Tour Edge CB Proh irons. Forged face hollow with a V-like sole in the 3-7 iron, these perform for me especially with the stock fujikura fuel reg. flex shaft. I never like the fat soles of hybrid irons, but these get through the turf very smoothly and as with the other v-sole clubs are more along the my target line than other clubs I’ve tried – and the distances are consistent too.

    So – the v-sole is really works in CBX, RTX-3, RTX-4, SCOR 4161. And in my experience mid handicap plays like myself can indeed play with forged clubs provided other parts of the club equation are in place for their swing dynamics.

    If one sets his adjustable club for a certain bias, wouldn’t it be a) more difficult to work the shot in the direction opposite the bias, and b) exacerbate a miss in the same direction as the bias?

      Makes great sense to me, and agree 100% with the wedge comment vs. the forged 9-iron. I play blades with confidence but struggle with my wedge play. What I get is I need more wedge/short game practice time. Very, very good news to know. Many thanks. Have not heard this comment from a professional instructor or club fitter to date.

    I’m still wondering why this dude has a sopabox to preach from. He’s killed every company he started, often soon after it starts, and knows so little about equipment he thinks spine and flow still matter when they haven’t been anything other than snake oil for 10 years.

    It was good to see Ben Hogan clubs come back into the industry, I only have one BH club and that is a forged 47* Apex Plus ‘E’ along with a Lovett LW which covers all the pitching and sand ploughing I need. Golf in the seventies with the smaller rubber wound balls and wooden clubs was a lot different from today.. When you bought a medium priced set of clubs (like Spalding) the highest loft was the 9 iron and you bought the PW and SW separately, how things have changed.

    • Bob Jones

      Ben Hogan clubs have never left. Go to eBay, buy a set of Red Line irons, and have them retro-fitted.

    Terry, that was a phenomenal piece. The secret re: Iron Byron and a tour 9 iron versus wedge absolutely blew me away. At my very best, I played to a plus 3.4. Played two years of mini tour golf and put 198,000 miles on a Honda Prelude, playing across North America. Today, I don’t even keep score. But all of the posts I read today, the clubs sold by players here, many soft and hard stepped, spined or pured, blah, blah, blah, blah… Leads me to wonder: How is the NGF SO WRONG about quality of play in 2019. Considering the equipment, EVERYONE must be a scratch player or better ????

    I grew up with a P and an S club and was a very good wedge player not knowing loft, bounce, grind or lie angle. We just bought those clubs stamped P and S and learned how to use them. I’m not sure I am a better wedge player today.

    Is it really so simple as to say more speed equals more distance? The physics of the club/ball interaction is elastic collision, which means momentum is what matters. Momentum is mass x velocity. More mass or more velocity equals more momentum, but if you change both variables in opposite ways, you can’t say for sure what happens to momentum.

      I would like to see more discussion about this. I tried discussing it once with our club pro but he sort of dismissed it.

      I believe the benefits of a heavier club have been overlooked by manufacturers. Heavier heads give more feedback and feeling during the swing and I feel that they are easier to swing on a natural plane. Plus the extra mass must be good at impact – getting hit by a bus at 30mph will know you a lot further than being hit a 30mph by a go cart – I think! or am I wrong?

      • geohogan

        Dec 29, 2019 at 7:25 am

        @CJB, totally agree

        Most club heads (drivers) decelerate at impact by 20-25%.

        Heavier heads will decelerate less, IF the shaft used is stiff enough and short enough.

        All top shafts have the same tip diameter. At a certain length of shaft, that tip diameter cannot stabilize the clubhead at impact, regardless how stiff.
        That limit of length is 45 inches.

        Only one shaft designer I know has done the calculations.

        His shaft, the Nunchuk is designed with the bend point near the center of the shaft, not near the tip. All twisting and bending occurs during the DS and not at impact, as long as total length is less than 45 inches.

        Shafts less than 45 inches in length(club length), can maintain SW with more weight in the clubhead, another plus, as you point out, CJB.
        This shaft design also eliminates gear effect as well as , deceleration at impact is less than 8%.

    I’ll never respect pros till clubs and golf balls get rolled back. Personally I think the equipment does to much work for them. Swing accuracy should matter more. They are very spoiled these days.

      The golf ball has been regulated for decades, since the original ODS was implemented. And, the ball was actually rolled back a bit when the new test protocols were introduced.

      The golf balls aren’t the problem.

      But even with all the modern tech they spray their tee shots every which way in pursuit of distance. I prefer to stay on the fairway.

        Aug 16, 2019 at 1:18 pm

        Have you been to a tour event before and saw them “spray it”? I’d love to have their “spray” shots. When you swing it 125MPH a degree or two off is a lot larger miss than when you’re swinging it 95MPH.

        If you’re playing a 7200 yard course first things first. You have to be long enough to play the course regardless of hitting a fairway. “I can stop my 9 iron out of the rough faster than you can stop your 6 iron from the fairway” -B Koepka

    What makes the ball go so much further is the ball. Modern drivers contribute but the biggest factor is the modern ball. It was when Nike then Titleist introduced the solid multi-layer ball that driving distances shot up.

    • NRJyzr

      Aug 13, 2019 at 4:10 pm

      Strata was the first solid core multilayer ball. Bridgestone was in there ahead of Nike, also.

      Driving distance change from the solid core ball was all of 5.5 yards. There was a bigger spike due to the mass move to 400cc+ drivers, and launch monitor introduction, a couple years later.

Equipment

Should you be using a blade or mallet putter?

Published

on

‘Should I use a blade or mallet putter?’ It’s a frequent question, and here we will provide you with our essential guide to help you decide.

Blade vs Mallet: Which style suits you?

As far as golf equipment goes, your putter may be the most critical item in your bag. That’s why it’s crucial to know the key features of both blade and mallet putters and what they are designed to provide so that you can closely identify which style of putter your stroke and game require to help you lower your scores.

Blade Putter

Scotty Cameron Blade Putter

The traditional blade putter features a sweet spot positioned closer to the heel and designed to offer maximum feel to golfers on the greens

A blade putter contains a traditional head shape and is a favorite amongst golf ‘purists’. Blade putters are heavily toe-weighted with a sweet spot positioned closer toward the heel. This sweet spot position is because the shaft connects to the club head of the blade at the heel or sometimes center of the blade. This heavy toe-weighting and heel sweet spot means that blade putters will typically suit players who have an arc in their putting stroke.

Mallet Putter

TaylorMade mallet putter

A mallet style putter gives players stability and balance in their stroke.

The more modern style mallet putter is a flat-stick with a larger head. The heads come in various shapes and sizes, and because of the size, a lot of the weight is often distributed away from the clubface so that players find plenty of stability and balance in their stroke. 

The ‘game improvement’ style of the mallet putter means that the larger sweet spot will help players who struggle to strike the ball directly in the center of the face, and the added weight in the clubhead is designed to prevent the putter twisting during the stroke.

Mallet putters also offer additional aid when it comes to alignment, offering more prominent features than a blade such as longer or added lines and can also benefit golfers who struggle to hit putts hard enough due to its heavier weight.

Do pros prefer blade or mallet style putters?

With the 2020 season in the books, we can take a look at who were the top-10 performers in the Strokes Gained: Putting department for 2020 and see what style of putter they used:

  1. Denny McCarthy: Scotty Cameron Tour-Only FastbackMallet
  2. Matthew Fitzpatrick: Yes C-Groove Tracy IIBlade
  3. Andrew Putnam: Odyssey White Hot RX No. 5Mallet
  4. Kristoffer Ventura: Scotty Cameron NewportBlade
  5. Kevin Na: Odyssey Toulon MadisonBlade
  6. Matt Kuchar: Bettinardi Kuchar Model 1Blade (Wide)
  7. Ian Poulter: Odyssey Stroke Lab SevenMallet
  8. Mackenzie Hughes: Ping Scottsdale TR Piper C Mallet
  9. Maverick McNealy: Odyssey ToulonBlade
  10. Bryson DeChambeau: SIK Tour prototypeBlade

Blade style 60% vs Mallet style 40%

Should I use a blade or mallet putter?

Typically, this choice comes down to feel and stroke. Your stroke, just like the stroke of a professional, is unique, and your stroke will determine which style of putter will help you perform best on the greens. Like any other club in your bag, fitting and testing is a key element that shouldn’t be overlooked.

That being said, there are two prominent strokes and identifying which category you fall into can help identify where you fall in the Blade vs Mallet putter debate..

Square-to-square stroke vs Arced stroke

Square-to-square stroke

A square-to square stroke is when the putter face is lined up square to the target, and the stroke is straight back and through. If you possess a natural square-to-square stroke, you may be more suited to a mallet putter. The reason for this is that a mallet putter is face-balanced with the center of gravity positioned toward the back of the club meaning the club is designed to stay square to the putter path all the way through the stroke.

Arced stroke

An arced stroke is when the putter face will open and close relative to the target, and the stroke travels on a slight curve. Should you possess an arced stroke, then a blade putter may be more suited for you because of the natural toe-weighting of the blade-style putter.

Other factors to consider

Feel players will also usually opt for a blade-style putter, due to the desire to feel the way the ball reacts off the putter face which allows them to have more control over their putting and to gain confidence. Mallet putters make ‘feel’ less easy to attain due to the softer inserts on the clubface.

Don’t put aside the issue of aesthetics when considering the issue too. The look of a putter can inspire confidence, and each individual will feel different when placing either a blade or mallet-style putter behind the ball at address, so choosing a style which makes you feel comfortable is an important aspect to consider.

Hopefully, you’ve now got more knowledge as to how you can find the right putter shape for you and your stroke. At the end of the day, the right putter for you, whether it’s a blade or mallet, will be the one which helps and inspires you to make more putts.

“There is no magic bullet in club fitting” – On Spec podcast

Published

on

On this week’s episode of the “On Spec” podcast on the GolfWRX radio network, the discussion was focused on all things club fitting and what it can and can’t do to help golfers.

One of the most important take-aways was about some of the misconceptions around how much a club fitting can help improve the results of a less than ideal swing.

“There is no magic bullet when it comes to fitting… It’s not to stop you from doing anything (in your golf swing) … But by going through a proper fitting, and process you can help reduce a miss (improving consitency)”
