Should you switch to a softer shaft if you’ve lost clubhead speed?

Published

on

The search for more clubhead speed drives many golfers in to see us for fittings. Many of these golfers walk in considering moving to a more flexible shaft as they’re getting older and think it will help them regain some of their lost yards. It’s at this point we usually interject and summarize what their goals are, but ask them to keep an open mind as to what shaft flex we end up in.

There are multiple reasons we do this: The first being that clubhead speed isn’t the only thing that matters when it comes to maximizing distance. Ball speed, launch angle, spin rates all play a bigger role than simple clubhead speed. The second is that by going to a softer shaft, you may not be getting more clubhead speed but may, in fact, be lowering it.

To start, I must give a little background of what the shaft does during the swing and compare it to a theoretical shaft that’s infinitely strong and stays perfectly straight during a swing. This theoretical shaft is shown in yellow on the captures below. Gears measures this relative clubhead speed with a metric called “kick.”

During the swing the shaft will cycle between lead and lag deflection.  The shaft reaches its maximum lag deflection shortly after the start of the downswing as the golfer starts to apply downward force and the mass of the clubhead lags behind.  Currently, the clubhead is moving slower than our theoretical shaft. That potential speed isn’t lost however, it’s stored in the shaft.

As the hands and club continue to move towards the ball, the shaft starts to release its stored energy and return to a neutral, straight position. As with any object that is flexed, the shaft passes the neutral, straight position and moves into lead deflection. It’s during this phase of releasing its stored energy that the clubhead is moving faster than the infinitely strong and perfectly straight shaft.  

Picture around half-way down, showing lead deflection and positive kick

For the flex of a shaft to contribute to the clubhead speed, the clubhead needs to hit the ball when that shaft is somewhere between maximum lag deflection and maximum lead deflection, so it has a positive “kick.” Timing is incredibly important on this!

What does this mean for you as a golfer? Unfortunately, there isn’t a simple “yes/no” answer if going to a more flexible shaft will help you pick up clubhead speed.

The first video shows a golfer swinging two different shafts. The shaft on the left (gold avatar) is an Accra FX 2.0 140 M1 and the one on the right (blue avatar) is an Accra FX 2.0 270 M4. The 270 M4 is a “stiff” flex, shaft weighing 70 grams, and the FX 2.0 140 is a 40-gram “ladies” flex. As you can see from the video there isn’t a significant difference in clubhead speed.

From the enlarged graph of the “kick” metric below, you can see there is some difference in the amount of speed the shaft is contributing to the clubhead and the M1 shaft is contributing 2.19 mph more to the clubhead than the stiffer M4. It’s just that other variables are negating this slight advantage, so the result is that the two shafts are basically even in terms of clubhead speed at impact.  

Expanded Kick Graph

This isn’t to say that a more flexible shaft will never help you pick up clubhead speed. The M1 shaft contributed over 3 mph more than the M4 did for this golfer. 

The takeaway in all of this is that there are many variables that go into creating clubhead speed and how any shaft reacts to your swing may be very different than how it reacts to others. I strongly suggest, that you test multiple shaft options and keep an open mind as to what shaft works the best for you. We’ve had several cases where putting a stiffer flex shaft is the right choice to help a golfer pick up distance, even if their clubhead speed doesn’t indicate it.  

Additionally, it’s not all about clubhead speed! When recommending shafts, we focus first on face mapping — or reducing the impact area grouping of where you hit the ball on the face. This leads to better launch angles, spin, ball speed and most importantly, dispersion.

    It’s incorrect common knowledge that more flex adds speed. Different flexes affect direction but mostly launch angle and spin. The biggest non swing factor for speed is shaft weight. A slower swinger would benefit from a 50 gram stiff over a 70 gram regular, even neither is optimal. Go lighter and shorter in the shaft settup to maximize speed and contact. It’s the better starting point in ones search for the right driver. But always default to the “whatever works” philosophy.

    Great article. Actually some truth about golf shafts. I am sure if given more print you could explain how shaft deflection / deceleration at impact greatly affects distance and direction.

      There is no such thing as deceleration…. its negative acceleration. Physics 101

      Hi Lane – Thanks for the feedback and you’re correct. We have found that the shaft flex rarely changes club head speed significantly, but it can have a significant impact on distance and dispersion. This is primarily through smash factor, dispersion and spin. We’ll get more in depth on that topic in a future article.

Vincenzi’s 2024 Zurich Classic of New Orleans betting preview

Published

on

The PGA TOUR heads to New Orleans to play the 2023 Zurich Classic of New Orleans. In a welcome change from the usual stroke play, the Zurich Classic is a team event. On Thursday and Saturday, the teams play best ball, and on Friday and Sunday the teams play alternate shot.

TPC Louisiana is a par 72 that measures 7,425 yards. The course features some short par 4s and plenty of water and bunkers, which makes for a lot of exciting risk/reward scenarios for competitors. Pete Dye designed the course in 2004 specifically for the Zurich Classic, although the event didn’t make its debut until 2007 because of Hurricane Katrina.

Coming off of the Masters and a signature event in consecutive weeks, the field this week is a step down, and understandably so. Many of the world’s top players will be using this time to rest after a busy stretch.

However, there are some interesting teams this season with some stars making surprise appearances in the team event. Some notable teams include Patrick Cantlay and Xander Schauffele, Rory McIlroy and Shane Lowry, Collin Morikawa and Kurt Kitayama, Will Zalatoris and Sahith Theegala as well as a few Canadian teams, Nick Taylor and Adam Hadwin and Taylor Pendrith and Corey Conners.

Past Winners at TPC Louisiana

  • 2023: Riley/Hardy (-30)
  • 2022: Cantlay/Schauffele (-29)
  • 2021: Leishman/Smith (-20)
  • 2019: Palmer/Rahm (-26)
  • 2018: Horschel/Piercy (-22)
  • 2017: Blixt/Smith (-27)

2024 Zurich Classic of New Orleans Picks

Tom Hoge/Maverick McNealy +2500 (DraftKings)

Tom Hoge is coming off of a solid T18 finish at the RBC Heritage and finished T13 at last year’s Zurich Classic alongside Harris English.

This season, Hoge is having one of his best years on Tour in terms of Strokes Gained: Approach. In his last 24 rounds, the only player to top him on the category is Scottie Scheffler. Hoge has been solid on Pete Dye designs, ranking 28th in the field over his past 36 rounds.

McNealy is also having a solid season. He’s finished T6 at the Waste Management Phoenix Open and T9 at the PLAYERS Championship. He recently started working with world renowned swing coach, Butch Harmon, and its seemingly paid dividends in 2024.

Keith Mitchell/Joel Dahmen +4000 (DraftKings)

Keith Mitchell is having a fantastic season, finishing in the top-20 of five of his past seven starts on Tour. Most recently, Mitchell finished T14 at the Valero Texas Open and gained a whopping 6.0 strokes off the tee. He finished 6th at last year’s Zurich Classic.

Joel Dahmen is having a resurgent year and has been dialed in with his irons. He also has a T11 finish at the PLAYERS Championship at TPC Sawgrass which is another Pete Dye track. With Mitchell’s length and Dahmen’s ability to put it close with his short irons, the Mitchell/Dahmen combination will be dangerous this week.

Taylor Moore/Matt NeSmith +6500 (DraftKings)

Taylor Moore has quickly developed into one of the more consistent players on Tour. He’s finished in the top-20 in three of his past four starts, including a very impressive showing at The Masters, finishing T20. He’s also finished T4 at this event in consecutive seasons alongside Matt NeSmith.

NeSmith isn’t having a great 2024, but has seemed to elevate his game in this format. He finished T26 at Pete Dye’s TPC Sawgrass, which gives the 30-year-old something to build off of. NeSmith is also a great putter on Bermudagrass, which could help elevate Moore’s ball striking prowess.

Vincenzi’s 2024 LIV Adelaide betting preview: Cam Smith ready for big week down under

Published

on

After having four of the top twelve players on the leaderboard at The Masters, LIV Golf is set for their fifth event of the season: LIV Adelaide. 

For both LIV fans and golf fans in Australia, LIV Adelaide is one of the most anticipated events of the year. With 35,000 people expected to attend each day of the tournament, the Grange Golf Club will be crawling with fans who are passionate about the sport of golf. The 12th hole, better known as “the watering hole”, is sure to have the rowdiest of the fans cheering after a long day of drinking some Leishman Lager.  

The Grange Golf Club is a par-72 that measures 6,946 yards. The course features minimal resistance, as golfers went extremely low last season. In 2023, Talor Gooch shot consecutive rounds of 62 on Thursday and Friday, giving himself a gigantic cushion heading into championship Sunday. Things got tight for a while, but in the end, the Oklahoma State product was able to hold off The Crushers’ Anirban Lahiri for a three-shot victory. 

The Four Aces won the team competition with the Range Goats finishing second.

2024 LIV Adelaide Picks

Cameron Smith +1400 (DraftKings)

When I pulled up the odds for LIV Adelaide, I was more than a little surprised to see multiple golfers listed ahead of Cameron Smith on the betting board. A few starts ago, Cam finished runner-up at LIV Hong Kong, which is a golf course that absolutely suits his eye. Augusta National in another course that Smith could roll out of bed and finish in the top-ten at, and he did so two weeks ago at The Masters, finishing T6.

At Augusta, he gained strokes on the field on approach, off the tee (slightly), and of course, around the green and putting. Smith able to get in the mix at a major championship despite coming into the week feeling under the weather tells me that his game is once again rounding into form.

The Grange Golf Club is another course that undoubtedly suits the Australian. Smith is obviously incredibly comfortable playing in front of the Aussie faithful and has won three Australian PGA Championship’s. The course is very short and will allow Smith to play conservative off the tee, mitigating his most glaring weakness. With birdies available all over the golf course, there’s a chance the event turns into a putting contest, and there’s no one on the planet I’d rather have in one of those than Cam Smith.

Louis Oosthuizen +2200 (DraftKings)

Louis Oosthuizen has simply been one of the best players on LIV in the 2024 seas0n. The South African has finished in the top-10 on the LIV leaderboard in three of his five starts, with his best coming in Jeddah, where he finished T2. Perhaps more impressively, Oosthuizen finished T7 at LIV Miami, which took place at Doral’s “Blue Monster”, an absolutely massive golf course. Given that Louis is on the shorter side in terms of distance off the tee, his ability to play well in Miami shows how dialed he is with the irons this season.

In addition to the LIV finishes, Oosthuizen won back-to-back starts on the DP World Tour in December at the Alfred Dunhill Championship and the Mauritus Open. He also finished runner-up at the end of February in the International Series Oman. The 41-year-old has been one of the most consistent performers of 2024, regardless of tour.

For the season, Louis ranks 4th on LIV in birdies made, T9 in fairways hit and first in putting. He ranks 32nd in driving distance, but that won’t be an issue at this short course. Last season, he finished T11 at the event, but was in decent position going into the final round but fell back after shooting 70 while the rest of the field went low. This season, Oosthuizen comes into the event in peak form, and the course should be a perfect fit for his smooth swing and hot putter this week.

Opinion & Analysis

The Wedge Guy: What really makes a wedge work? Part 1

Published

on

Of all the clubs in our bags, wedges are almost always the simplest in construction and, therefore, the easiest to analyze what might make one work differently from another if you know what to look for.

Wedges are a lot less mysterious than drivers, of course, as the major brands are working with a lot of “pixie dust” inside these modern marvels. That’s carrying over more to irons now, with so many new models featuring internal multi-material technologies, and almost all of them having a “badge” or insert in the back to allow more complex graphics while hiding the actual distribution of mass.

But when it comes to wedges, most on the market today are still single pieces of molded steel, either cast or forged into that shape. So, if you look closely at where the mass is distributed, it’s pretty clear how that wedge is going to perform.

To start, because of their wider soles, the majority of the mass of almost any wedge is along the bottom third of the clubhead. So, the best wedge shots are always those hit between the 2nd and 5th grooves so that more mass is directly behind that impact. Elite tour professionals practice incessantly to learn to do that consistently, wearing out a spot about the size of a penny right there. If impact moves higher than that, the face is dramatically thinner, so smash factor is compromised significantly, which reduces the overall distance the ball will fly.

Every one of us, tour players included, knows that maddening shot that we feel a bit high on the face and it doesn’t go anywhere, it’s not your fault.

If your wedges show a wear pattern the size of a silver dollar, and centered above the 3rd or 4th groove, you are not getting anywhere near the same performance from shot to shot. Robot testing proves impact even two to three grooves higher in the face can cause distance loss of up to 35 to 55 feet with modern ‘tour design’ wedges.

In addition, as impact moves above the center of mass, the golf club principle of gear effect causes the ball to fly higher with less spin. Think of modern drivers for a minute. The “holy grail” of driving is high launch and low spin, and the driver engineers are pulling out all stops to get the mass as low in the clubhead as possible to optimize this combination.

Where is all the mass in your wedges? Low. So, disregarding the higher lofts, wedges “want” to launch the ball high with low spin – exactly the opposite of what good wedge play requires penetrating ball flight with high spin.

While almost all major brand wedges have begun putting a tiny bit more thickness in the top portion of the clubhead, conventional and modern ‘tour design’ wedges perform pretty much like they always have. Elite players learn to hit those crisp, spinny penetrating wedge shots by spending lots of practice time learning to consistently make contact low in the face.

So, what about grooves and face texture?

Grooves on any club can only do so much, and no one has any material advantage here. The USGA tightly defines what we manufacturers can do with grooves and face texture, and modern manufacturing techniques allow all of us to push those limits ever closer. And we all do. End of story.

Then there’s the topic of bounce and grinds, the most complex and confusing part of the wedge formula. Many top brands offer a complex array of sole configurations, all of them admittedly specialized to a particular kind of lie or turf conditions, and/or a particular divot pattern.

But if you don’t play the same turf all the time, and make the same size divot on every swing, how would you ever figure this out?

The only way is to take any wedge you are considering and play it a few rounds, hitting all the shots you face and observing the results. There’s simply no other way.

So, hopefully this will inspire a lively conversation in our comments section, and I’ll chime in to answer any questions you might have.

And next week, I’ll dive into the rest of the wedge formula. Yes, shafts, grips and specifications are essential, too.
