Head to Head: Callaway Apex CF ’16, Mizuno JPX-900 Forged and Srixon Z565 irons

Published

on

A few weeks ago, GolfWRX Members voted for the three game-improvement irons they most wanted to see tested head-to-head. The winners were: Callaway Apex CF ’16, Mizuno JPX-900 Forged and Titleist 716 AP1. Unfortunately, I was not able to access a Titleist 716 AP1 at my desired specs (62-degree lie, 32-degree loft), so it was replaced in the test by the iron that got the next highest amount of votes, Srixon’s Z565 irons.

I do a lot of these head-to-head equipment test videos on my YouTube Channel, but for this video I stepped it up. Each of the three irons were tested with the same shafts of the exact same length, and all the clubs had the same grips, lofts, lies and swing weights, courtesy of Tour X Golf fitters.

    Rick,

    It seems you Averaged 4mm toe on the Apex, and 5mm toe on the srixon – and the shots all went left….. Mizuno averaged 1mm toe and actually dispersed tighter to the line, not all grouped left. Also, you had 1.4deg and 1.6 deg of side spin with the Callaway and Srixon respectively, vs. 3.6 degrees of side spin with mizuno. This could’ve held it from achieving more distance, but more like it seems, it was third in your test, and you miss hit it more often as you tired. I would like to see you stagger the test, 1 callaway, 1 srixon, 1 mizuno…etc to produce a real test. Also, Mizuno is the only full forged head in the group – the other are multi-material constructions.

    It doesn’t matter what the loft is. The COG and even proscribed shaft the engineers (occasionally) designed it around to produce the loft needed for the ‘X’ to play as it should. A (‘7’) iron needs to achieve a ball flight apex to land softly. If it does and yields more distance then they did thier job – well.

    In ’97 I played Diawa Comps. Took a bit of ‘getting used to’
    as they looked like shovels compared to my Miura’s, TZoids
    or VIP’s but the thin Titanium face and sharp grooves
    allowed for Tungsten inserts to lower the CG enough they
    went plenty high, stopped dead with 5irons or got nice draw with a 6 on the greens and were almost 20yds longer. A well needed boost following 3 fractured vertibrea and lead shoulder/hand injuries.

    Everyrhing has changed dramatically in 40 years. Jack coulda hit a 200yd 7 iron back then, it just never would of stopped on the green. Even most ‘players’ clubs PW have gone from 48 to 46 or 46.5 because the balls & shafts and better head design allow for it.

    Great work running these tests – and yes, even the grip should be the same. The heads however should be checked to be exact MFR lofts – whether or not there’s a difference between the club’s designated ‘number’…the launch data will tell us if one has been made ‘too strong’ and comes into a green too hot.

    thanks for doing these 🙂

    So what you are saying is a lot more people are striping 2 or even 1 irons down the fairway nowadays. Amazing.

    I like that you are getting away from numbers on the clubs as that loft was called a 5 iron when I started playing golf. You shouldn’t even mentioned the marketing number on the bottom of the club, but if someone needs to think that they hit their club with a 7 on it the same distance as my club with a 5 on it – whatever turns their crank. What was the length of the irons? All 37 inches?

      I get so sick of listening to people complain about the loft vs. Number on the bottom of your club. Nobody cares what the 5i was back in your day…you also walked to school in the snow, uphill, both ways.

      I bet your 5 iron of yester-year didn’t launch the ball as high as the current 7 irons.

        Wow – hit a nerve eh? Didn’t know back in the day was only 5 years ago – what, you age in dog years? Chill dude – reviewing taking about lofts inside of what has become a meaningless number only makes it easier to compare apple to apples. Oh, and a higher launch isn’t always needed or better – horses for courses.

      You score is what counts in golf, right? If it makes you feel better to have a “traditional” lofted 7 iron, go for it. I see no difference though in someone wanting a non “traditional” 7 iron, than what you want and as long as fitted for the clubs. It makes zero difference. Heck, you are free to use a persimmon 1 wood with a 20 year old steel shaft if that makes you feel better. Just hit the ball and have fun. If it worries you that someone says they hit their 7 iron longer than your 7 iron, eh, I think you just need to let it go and learn to give jabs right back about something else.
      For kicks though, go take a 7 iron from decades ago and get on trackman and compare to these newer lower lofted 7 irons. I think you’ll quickly understand the reasons for lower lofts these days vs more traditional lofts. If that doesn’t make sense to you, then go bend the loft down on a 20 year old 7 iron to match today’s lofts (~30 degrees) and see what you get on the course. Let me know how those bullets work out as they only go a few yards off the ground and skid off the back of a green. It is more than just the loft.
      No matter how you look at it, everyone has to hit the club and post a score no matter what is stamped on the club. And if you really think about it, there is no “standard” loft any longer.
      And beyond lofts, the is no standard on what “regular”, “stiff” etc. means in shafts yet many take it for granted those all mean the same thing across manufacturers. They don’t.
      Get fitted. If you end up with a 35 degree 7 iron, bravo. If its 28 degrees, bravo as well.

        Another nerve pinched :o) – for the record I have been getting fitted for a while and have ended up with clubs from 2006 that are only “one” number behind the current crop and from what I see there never was a standard so why even bother with random numbers on clubs. Personally I couldn’t care less about the numbers because in the end I decide on clubs via lofts to space my yardages. However, the effect of the decreased lofts and increased lengths just means I have to tweak lofts more than before and add more lead tape than before after cutting down the shaft lengths, as the OEMs use lighter heads to prevent the swing weights from getting to heavy with the longer lengths. My club selection is based on what I need to get my lowest score. I don’t care about the numbers on my clubs, I figure out the lofts that work – my 3W is the length of a 2W (42.5 inches) with the loft of a 4W (18), or is that a 7W now… I don’t care, as in the end all I need is to figure out the length/loft combination that maximizes my potential – the numbers on the clubs are irrelevant other than to make it easier to pull a club. Only makes it a bit trickier when looking for clubs to replace worn out ones.

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.

Vincenzi’s 2024 RBC Heritage betting preview: Patrick Cantlay ready to get back inside winner’s circle

Published

on

Just a two-hour drive from Augusta National, the PGA TOUR heads to Harbour Town Golf Links in Hilton Head Island, S.C. Hilton Head Island is a golfer’s paradise and Harbour Town is one of the most beautiful and scenic courses on the PGA TOUR.

Harbour Town Golf Links is a par-71 that measures 7,121 yards and features Bermuda grass greens. A Pete Dye design, the course is heavily tree lined and features small greens and many dog legs, protecting it from “bomb-and-gauge” type golfers.

The field is loaded this week with 69 golfers with no cut. Last year was quite possibly the best field in RBC Heritage history and the event this week is yet another designated event, meaning there is a $20 million prize pool.

Most of the big names on the PGA Tour will be in attendance this week with the exceptions of Hideki Matsuyama and Viktor Hovland. Additionally, Webb Simpson, Shane Lowry, Gary Woodland and Kevin Kisner have been granted sponsors exemptions. 

Past Winners at Harbour Town

  • 2023: Matt Fitzpatrick (-17)
  • 2022: Jordan Spieth (-13)
  • 2021: Stewart Cink (-19)
  • 2020: Webb Simpson (-22)
  • 2019: CT Pan (-12)
  • 2018: Sotoshi Kodaira (-12)
  • 2017: Wesley Bryan (-13)
  • 2016: Branden Grace (-9)
  • 2015: Jim Furyk (-18)

Key Stats For Harbour Town

Let’s take a look at key metrics for Harbour Town Golf Links to determine which golfers boast top marks in each category over their past 24 rounds.

Strokes Gained: Approach

Strokes Gained: Approach is exceedingly important this week. The greens at Harbour Town are about half the size of PGA TOUR average and feature the second-smallest greens on the tour. Typical of a Pete Dye design, golfers will pay the price for missed greens.

Total SG: Approach Over Past 24 Rounds

  1. Scottie Scheffler (+1.27)
  2. Tom Hoge (+1.27)
  3. Corey Conners (+1.16)
  4. Austin Eckroat (+0.95)
  5. Cameron Young (+0.93)

Good Drive %

The fairways at Harbour Town are tree lined and feature many dog legs. Bombers tend to struggle at the course because it forces layups and doesn’t allow long drivers to overpower it. Accuracy is far more important than power.

Good Drive % Over Past 24 Rounds

  1. Brice Garnett (88.8%)
  2. Shane Lowry (+87.2%)
  3. Akshay Bhatia (+86.0%)
  4. Si Woo Kim (+85.8%)
  5. Sepp Straka (+85.1%)

Strokes Gained: Total at Pete Dye Designs

Pete Dye specialists tend to play very well at Harbour Town. Si Woo Kim, Matt Kuchar, Jim Furyk and Webb Simpson are all Pete Dye specialists who have had great success here. It is likely we see some more specialists near the top of the leaderboard this week.

SG: TOT Pete Dye per round over past 36 rounds:

  1. Xander Schauffele (+2.27)
  2. Scottie Scheffler (+2.24)
  3. Ludvig Aberg (+2.11)
  4. Brian Harman (+1.89)
  5. Sungjae Im (+1.58)

4. Strokes Gained: Short Game (Bermuda)

Strokes Gained: Short Game factors in both around the green and putting. With many green-side bunkers and tricky green complexes, both statistics will be important. Past winners — such as Jim Furyk, Wes Bryan and Webb Simpson — highlight how crucial the short game skill set is around Harbour Town.

SG: SG Over Past 24 Rounds

  1. Jordan Spieth (+1.11)
  2. Taylor Moore (+1.02)
  3. Wyndham Clark (+0.98)
  4. Mackenzie Hughes (+0.86)
  5. Andrew Putnam (+0.83)

5. Greens in Regulation %

The recipe for success at Harbour Town Golf Links is hitting fairways and greens. Missing either will prove to be consequential — golfers must be in total control of the ball to win.

Greens in Regulation % over past 24 rounds:

  1. Brice Garnett (+75.0%)
  2. Scottie Scheffler (+69.9%)
  3. Corey Conners (+69.0%)
  4. Shane Lowry (+68.3%)
  5. Patrick Rodgers (+67.6%)

6. Course History

Harbour Town is a course where players who have strong past results at the course always tend to pop up. 

Course History over past 24 rounds:

  1. Patrick Cantlay (+2.34)
  2. Cam Davis (+2.05)
  3. J.T. Poston (+1.69)
  4. Justin Rose (+1.68)
  5. Tommy Fleetwood (+1.59)

The RBC Heritage Model Rankings

Below, I’ve compiled overall model rankings using a combination of the five key statistical categories previously discussed — SG: Approach (24%), Good Drives (20%), SG: SG (14%), SG: Pete Dye (14%), GIR (14%), and Course History (14%)

  1. Shane Lowry
  2. Russell Henley
  3. Scottie Scheffler
  4. Xander Schauffele
  5. Corey Conners 
  6. Wyndham Clark
  7. Christiaan Bezuidenhout
  8. Matt Fitzpatrick
  9. Cameron Young
  10. Ludvig Aberg 

2024 RBC Heritage Picks

Patrick Cantlay +2000 (FanDuel)

With the exception of Scottie Scheffler, the PGA Tour has yet to have any of their star players show peak form during the 2024 season. Last week, Patrick Cantlay, who I believe is a top-5 players on the PGA Tour, took one step closer to regaining the form that’s helped him win eight events on Tour since 2017.

Cantlay limped into the Masters in poor form, but figured it out at Augusta National, finishing in a tie for 20th and ranking 17th for the week in Strokes Gained: Ball Striking. The former FedEx Cup champion will now head to one of his favorite golf courses in Harbour Town, where he’s had immaculate results over the years. In his six trips to the course, he’s only finished worse than 7th one time. The other finishes include three third places (2017, 2019, 2023) and one runner-up finish (2022). In his past 36 rounds at Harbour Town, Cantlay ranks 1st in Strokes Gained: Total per round at the course by a wide margin (+2.36).

Cantlay is winless since the 2022 BMW Championship, which is far too long for a player of his caliber. With signs pointing to the 32-year-old returning to form, a “signature event” at Harbour Town is just what he needs to get back on the winning track.

Tommy Fleetwood +3000 (FanDuel)

I truly believe Tommy Fleetwood will figure out a way to win on American soil in 2024. It’s certainly been a bugaboo for him throughout his career, but he is simply too talented to go another season without winning a PGA Tour event.

At last week’s Masters Tournament, Fleetwood made a Sunday charge and ended up finishing T3 in the event, which was his best ever finish at The Masters. For the week, the Englishman ranked 8th in the field in Strokes Gained: Approach, 10th in Strokes Gained: Ball Striking and 16th in Strokes Gained: Putting.

Harbour Town is a perfect layout for Fleetwood, and he’s had relative success at this Pete Dye design in the past.  In his four trips to the course, he’s finished inside of the top 25 three times, with his best finish, T10, coming in 2022. The course is pretty short and can’t be overpowered, which gives an advantage to more accurate players such as Fleetwood. Tommy ranks 8th in the field in Good Drive % and should be able to plot his way along this golf course.

The win is coming for Tommy lad. I believe there’s a chance this treasure of a golf course may be the perfect one for him to finally break through on Tour.

Cameron Young +3300 (FanDuel)

Cameron Young had a solid Masters Tournament last week, which is exactly what I’m looking for in players who I anticipate playing well this week at the RBC Heritage. He finished in a tie for 9th, but never felt the pressure of contending in the event. For the week, Young ranked 6th in Strokes Gained: Off the Tee and 6th in Strokes Gained: Ball Striking.

Despite being one of the longest players off the tee on the PGA Tour, Young has actually played some really good golf on shorter tracks. He finished T3 at Harbour Town in 2023 and ranks 20th in the field in Good Drive% and 16th in Greens in Regulation in his past 24 rounds. He also has strong finishes at other shorter courses that can take driver out of a players hand such as Copperhead and PGA National.

Young is simply one of the best players on the PGA Tour in 2024, and I strongly believe has what it takes to win a PGA Tour event in the very near future.

Corey Conners +5500 (FanDuel)

Corey Conners has had a disappointing year thus far on the PGA Tour, but absolutely loves Harbour Town.

At last week’s Masters Tournament, the Canadian finished T30 but ranked 20th in the field in Strokes Gained: Approach. In his past 24 rounds, Conners ranks 3rd in the field in Strokes Gained: Approach, 3rd in Greens in Regulation % and 24th in Good Drive %.

In Conners’ last four trips to Harbour Town, his worst finish was T31, last season. He finished T4 in 2021, T12 in 2022 and ranks 8th in Strokes Gained: Total at the course over his past 36 rounds.

Conners hasn’t been contending, but his recent finishes have been encouraging as he has finished in the top-25 in each of his past three starts prior to The Masters, including an impressive T13 at The PLAYERS. His recent improvement in ball striking as well as his suitability for Harbour Town makes Conners a high upside bet this week.

Shane Lowry (+7500) (FanDuel)

When these odds were posted after Lowry was announced in the field, I have to admit I was pretty stunned. Despite not offering much win equity on the PGA Tour over the last handful of years, Shane Lowry is still a top caliber player who has the ability to rise to the top of a signature event.

Lowry struggled to score at The Masters last week, but he actually hit the ball really well. The Irishman ranked 1st for Strokes Gained: Approach on the week and 7th in Strokes Gained: Ball Striking. As usual, it was the putter that let him down, as he ranked 60th in the field in Strokes Gained: Putting.

Harbour Town is most definitely one of Lowry’s favorite courses on the PGA Tour. In his six starts there, he’s finished in the top 10 three times, including third twice. Lowry is sensational at Pete Dye designs and ranks 7th in Strokes Gained: Total in his past 36 rounds on Dye tracks. 

Lowry is perfect for Harbour Town. In his past 24 rounds, he ranks 5th in Strokes Gained: Approach, 2nd in Good Drive% and 5th in Green in Regulation %. If he figures it out on the greens, Shane could have his first win in America since 2015.

Lucas Glover +12000 (FanDuel)

This is one of my weekly “bet the number” plays as I strongly believe the odds are just too long for a player of Glover’s caliber. The odds have been too long on Glover for a few weeks now, but this is the first event that I can get behind the veteran being able to actually contend at. 

Glover is quietly playing good golf and returning to the form he had after the understandable regression after his two massive victories at the end of 2023. He finished T20 at The Masters, which was his best ever finish at Augusta National. For the week, Lucas ranked 18th for Strokes Gained: Approach and 20th in Strokes Gained: Ball Striking.

Over his past 24 rounds, Glover ranks 9th in Strokes Gained: Approach and 13th in Good Drive %. Harbour Town is a short course that the 44-year-old will be able to keep up with the top players on Tour off the tee. He’s played the course more than 20 times, with mixed results. His best finishes at Harbour Town include a T7 in 2008, but recently has a finish of T21 in 2020.

Glover has proven he can contend with the stars of the Tour on any given week, and this number is flat out disrespectful.
