TOUR REPORT: Jon Rahm’s custom Masters-winning clubs, Adam Scott switches iron shafts AGAIN?!
Well, the Masters is over. I know it hurts to say goodbye, but as the countdown already begins for next year’s event, the PGA Tour rolls right into the elevated 2023 RBC Heritage Classic this week where the players will compete for a $20 million prize, with a $3.6 million first place check going to the winner. For those counting, the RBC actually has a larger purse than the $18 million dollar Masters purse and $3.24 million winner’s cut. Big bucks on the line.
The venue is Harbour Town Golf Links, arguably the most narrow golf course on the PGA Tour rotation.
Ahead of the event, GolfWRX took a look at what the PGA Tour’s top players are using this week.
Most notably, we got a look at 2023 Masters Champion Jon Rahm’s Masters-winning gear setup, and we spoke to his fitters. But way more on that later.
In other gear news from the week, we got a look at the WITBs of two active legends: Davis Love III and Ernie Els. We also saw Tom Kim’s new putter, Tommy Fleetwood’s new TaylorMade “BRNR Mini Driver,” Adam Scott’s new iron shafts (yes, he changed again!), Joel Dahmen’s “new” putter, and Jimmy Walker’s new AutoFlex shafts.
Let’s get into this week’s Tour Report from the 2023 RBC Heritage.

Jon Rahm’s post-Masters WITB

If Jon Rahm would have withdrawn from the RBC Heritage this week, I don’t think anyone would have blamed him. But, in great form and good faith, he’s fulfilling his commitment to play. Much respect.
As an up-close observer myself, it was a king’s welcome to Harbour Town for Rahm. He was getting much due love from the fans, from his playing peers, from caddies…from everyone.
Plus, all of us gearheads owe Rahm a big “thank you,” because his appearance in the event allowed us to get a look at his Masters-winning gear, just days following the victory.

Check out photos of the clubs he brought to the RBC Heritage this week below, and check out GolfWRX/PGA Tour collaborative video of his clubs in the Instagram video above (he changed out the actual Masters-green, limited-edition Callaway staff bag from last week, and went into the new Odyssey staff bag):

The only changes that Rahm’s looking at making this week are adding in a Callaway Apex UT 21-degree driving iron (which is a course dependent club already) in place of his Paradym Triple Diamond T-model 5-wood, and also adding in a fresh 60-degree wedge.
Aside from that, Rahm almost never changes his equipment, so it’s no surprise that he didn’t do any post-Masters tinkering at Harbour Town.

Why does Rahm have the number 10 stamped on his wedges? According to Callaway, the answer is simple: he’s a big soccer fan (or futbol, if you prefer), and a soccer/futbol team’s main striker or captain typically wears No. 10.
Moving along.

This week over on PGATOUR.com, I dove deep into Rahm’s unique irons, and what makes them different than standard. Here’s a snippet, as explained by Callaway Tour rep Kellen Watson:
“When he came over [to Callaway], we found out quickly that we needed to have soft-stepped 6.5s in his irons,” Watson told GolfWRX.com on Tuesday at the 2023 RBC Heritage. “Usually what we do with all our guys is do a performance combine. We do about 60 shots using clubs throughout the bag and never two of the same shots in a row. So, it could go 4-iron to 9-iron, 9-iron to 5-iron, 5-iron to 6-iron, 6-iron to wedge. We capture all that data and it’ll give us pretty much everything we need to know. During that process, when he first came over, we did that, compiled the data, we ate lunch, then we went back after bending all the irons loft and lie wise, and we got to the numbers that are his current loft and lie. They might appear like they’re a half-degree weak from standard, but there is no standard on the PGA TOUR. Spin-wise, he’s going to be right around 6,000-6,300 in spin [with the 6 iron], and that pretty much stays the same at whatever launch angle he hits it.”
Check out Rahm’s full WITB on video, or in our photos in the GolfWRX Forums.
Tom Kim explains his putter switch

Kim has been using mostly Scotty Cameron custom blade putters since coming onto the PGA Tour, but he switched into a T5.5 mallet head at the Masters. The putter was custom built with a plumbers neck to match the neck style of his usual blade putters, and also, the three white alignment lines were placed to match up with an older Scotty Cameron mallet that he used while in Korea, and in his early days on Tour.
Here’s what Kim had to say about making the switch:
“I used a mallet head a few years back before I switched to a blade – I was always a blade putter, then went to a mallet for a year, and went back to the blade,” Kim told GolfWRX.com on Tuesday at the RBC Heritage. “I just wasn’t feeling comfortable all the sudden. I wanted to go back to something bigger and more comfortable. Obviously they’ve helped a bunch with the neck, because I didn’t want to go too far off what I was using with the blade, because I was putting well. It’s the exact same look and shape [that I used before]. I practiced with it, putted great, and made the switch. It’s looking good. It’s what I’ve used before with the lines. It feels like I’ve gone back to an old friend.”
Familiarity and comfort can help a lot, especially with the putter.

Jimmy Walker puts AutoFlex shafts in his driver and 3-wood

Over the past several years, Walker has run the gamut of shaft options in his drivers, using everything from a stiff steel shaft to the new ultra-whippy AutoFlex, and everything in between. He said his club pro back home recently built up the heads with AutoFlex XX shafts, and he’s been using them for the last several weeks. Walker told GolfWRX on Tuesday that the AutoFlex shafts are different than anything he’s ever tried, and he loves them so far.

Walker has AutoFlex XX shafts in his Callaway Paradym Triple Diamond 9-degree driver head, and in his Paradym 15-degree fairway wood.

And just like that, Adam Scott switches iron shafts again

As a reminder, just days before the start of the 2023 Masters last week, Adam Scott said he was “winging it,” with a number of last-minute equipment changes.
So, he changed his golf ball to a new 2023 Pro V1x golf ball (after using the 2015 Pro V1 previously). He then changed his driver shaft to a Fujikura Ventus TR Blue 7 X in his TaylorMade Stealth 2 Plus driver, and he changed into new Project X LZ 6.5 iron shafts in his entire Miura AS-1 iron set.

Fast forward to this week ahead of the 2023 RBC Heritage Classic, and Scott is continuing to switch things up. This week, he switched out of the Project X LZ 6.5 shafts he used at Augusta National, and he’s switching into True Temper Dynamic Gold Tour Issue X100 shafts.
Scott isn’t letting up on the equipment switches, and personally, I’m finding it extremely entertaining. The GolfWRX members are weighing in with their similar opinions here.
It’s seriously pretty cool, and informative, to follow along. We’re seeing the equipment fitting process happen in real time. He’s changing a number of variables on the fly and trying to figure out what works exactly right.
Making a golf ball switch can be a big change for PGA Tour players who rely on their precision. In their minds, it’s not just a “golf ball.” It needs to hit certain spin and launch windows. That’s how these guys get so dialed in on their targets, while also maximizing distance off the tee.
Here’s what Scott said himself about all the changes, following his opening round 68 at the Masters (he ultimately finished T39):
“I did some pretty major overhauling of my equipment, actually, that may not be a hundred percent comfortable, but certainly I saw some benefit from doing that. I changed some shafts in my irons and my driver, and my golf ball, so I’m kind of winging it a little bit out there. But it all feels pretty good. I putted very nicely today and that’s always helpful around here.”
“Things change and evolve, and a couple pieces of equipment in my bag have changed over the last year or so, and it’s having some influence as well as me swinging the club maybe slightly differently on my impact conditions. And with a shaft change and the (2023) Pro V1x, it’s balancing out really nicely and keeping that new ball in the window I like. Whereas before it was a little bit higher window and this is now sitting in a window that I feel much more comfortable with, which is nice. It’s very tight on the iron spin. I’m getting a really tight performance there, which is a good feeling for me. And also I get the added benefit of a higher ceiling with the driver. I’m gaining without doing anything by just using this ball off the tee. So hopefully I can make a few little gains here and there by using the Pro V1x without having to change anything else in my game, just putting it in play.”
My takeaway is that we as amateurs should pay attention to what the pros say about changes like this, and apply it to our own games. The best way to go about picking a golf ball for yourself is to get with a professional fitter or your local pro, tell them you’re trying to pick a golf ball and you want a proper fitting, and they’ll surely be willing to help – possibly for $free.99, possibly for a fee, it just depends where you go. Some companies do free fittings in your area if you don’t have a local simulator or outdoor range fitting access, so in that case, Google is your friend there to find a deal. But either way, it’d probably cost less than a dozen golf balls to get a fitting. Then, going forward, you’ll know which golf ball is truly best for you. There are real benefits to be found, like distance, spin and forgiveness, and all companies make slightly different balls designed to do different things. Test everything!
Then, hopefully you use the same golf ball for eight years like Scott has until you find something truly better.
Davis Love III WITB

Davis Love III, a five-time winner of the event, has a bag full of Titleist equipment in the bag this year, including a new TSR3 driver, an older TS3 fairway wood, a T200 driving iron, a set of T100 irons, new SM9 wedges, and a Scotty Cameron TourType Masterful blade-style putter with a dot for the alignment aid.

Ernie Els WITB

GolfWRX took a look into another legendary golfer’s bag this week, too: Ernie Els.
Els is currently using a XXIO driver and 3-wood, Srixon ZK7 Mk II irons, Cleveland RTX-6 Tour Rack wedges (the rust game is strong), and an Odyssey O-Works putter that’s loaded up with lead tape on the sole.

See more photos of Els’ WITB here
Tommy Fleetwood is expected to give the new Mini Driver a go
A number of players tested and used a new TaylorMade BRNR Mini Driver model at the Masters (including Freddie Couples!), and it’s expected that Fleetwood will join the list of mini users this week.

Although TaylorMade is staying quiet for now about the technology and design, the BRNR appears to feature TaylorMade’s old school logos, nostalgic colorways, and it has a hint of burnt orange/bronze coloring on the crown in the sunlight, as pictured above. According to Fleetwood’s caddie Ian Finnis, Fleetwood “smashes” the new 13.5-degree club, and it’s going into the bag this week along with a driver, 5-wood, 3-iron setup configuration at the top end.
See what the GoflWRX members are saying about the BRNR
Joel Dahmen’s “new” Scotty Cameron putter

Dahmen was already a fan-favorite before he was featured in Netflix’s new Full Swing series, and his star power has only grown since. And, if he continues to use awesome custom putters like this Scotty Cameron Round Back proto, he may just win over all the gearheads, too.

The sole of the putter may appear to feature green paintfill (look where it says “Round Back” and “Proto”), but it’s actually a result of the torching process on the bronze putter. GolfWRX Equipment Expert Brian Knudson already went in-depth on Dahmen’s putter, so click here if you want more information.
And, with that, we unfortunately say goodbye to Harbour Town and the 2023 RBC Heritage. We’ll be back in action next week for the 2023 Zurich Classic of New Orleans, which is a 2-man team event.
Enjoy the weekend of golf, and don’t forget to get out there on the course yourself (and don’t forget to talk to a local fitter or club pro about a golf ball fitting!). Happy testing.

TaylorMade MySpider Tour and Tour X: More customizable build options now available
TaylorMade Golf’s MySpider program underwent a substantial overhaul over the last month. Firstly, the company launched the option to customize the Spider ZT model, and now the program has returned with the MySpider Tour and MySpider Tour X.
The revamped page now gives golfers complete control over every visual and functional detail of their putter on the popular Tour and Tour X head, with every cosmetic idea thought of. In MySpider Tour, golfers can choose from four head finishes, 16 paint fill colors, nine Surlyn face insert colors, three aluminum insert options, six sightline configurations, and four hosel options — L-neck, small slant, double bend, center shaft. Six sightline options are available in MySpider Tour, including the optically engineered True Path alignment system. MySpider Tour X gives builders the option of four head finishes, four hosel configurations, and five sightline options, also including True Path alignment.
One of the more interesting features of the new MySpider program is the availability of three distinct face insert options. Along with the usual Surlyn Pure Roll insert trusted by Scottie Scheffler and Rory McIlroy, which can be customized from nine colors, golfers can now also select firmer options. Two are offered with the black aluminum Pure Roll insert, slightly firmer than the traditional insert, or for the firmest feel, golfers can choose from two colors of milled aluminum inserts.

Another fun addition to the MySpider Tour is the ability to use the “Tommy Sightline.” The custom alignment aid design, which was first drawn onto Tommy Fleetwood’s putter by PGA Tour Rep James Holley, is based on the milled sightline on his Spider ZT head. There are five shorter lines on the left and right of a longer central line serving as the traditional short line alignment aid.

Then and now: Comparing Rory McIlroy’s current setup to his record-breaking 2019 Canadian Open victory
In Rory McIlroy’s first appearance at the 2019 RBC Canadian Open, he crushed the record books to earn his 16th PGA Tour title in dominating fashion, winning by seven shots over Shane Lowry and Webb Simpson.
McIlroy’s score of 22-under-par 258 is the lowest 72-hole score to date at the Canadian Open, and his closing 61 is also the best final-round score in the history of one of golf’s oldest tournaments. Finally, with his win in 2019, McIlroy became only the sixth player to win the career Triple Crown, adding to his victories at the U.S. Open in 2011 and The Open Championship in 2014, joining Tommy Armour, Walter Hagen, Arnold Palmer, Lee Trevino and Tiger Woods in a coveted list.
So, with that, why not compare his current setup to the clubs he used to break all the records?
Driver
2019: TaylorMade M5 (9 degrees), Shaft: Mitsubishi Tensei CK Pro White 70 TX
2026: TaylorMade Qi4D (9 degrees @8), Shaft: Fujikura Ventus Black 7X (45 5/8 inches)

McIroy led the Tour in Strokes Gained: Off-the-Tee in 2019; he’s doing the same in 2026. Between now and then, McIlroy has switched from the Mitsubishi Tensei CK Pro White 70 TX (a shaft with slightly more feeling in the tip) to the original Fujikura Ventus Black 7X, having just made the change to the heavier version from playing the 60X.
What’s interesting about McIlroy’s 2019 setup is that the weighting on his driver is actually set in the high-draw setting, using the T-Track weighting system, whereas in the Qi4D, he’s currently using a heavily rear-weighted setup. (Two 13-gram weights in the rear and only two 4-gram front weights.)
The TaylorMade M5 driver he played in during his Canadian Open win was the company’s first head that they claimed to design to initially exceed the USGA’s COR limit, and then injected with tuning resin to bring it back in bounds.
Fairway woods
2019: TaylorMade M6 3-wood (15 degrees), Shaft: Mitsubishi Tensei CK Pro White 80 TX; TaylorMade M5 5-wood (19 degrees), Shaft: Mitsubishi Tensei CK Pro White 90 TX
2026: TaylorMade Qi4D 3-wood (15 degrees), Shaft: Fujikura Ventus Black 8X; TaylorMade Qi4D 5-wood (18 degrees), Shaft: Fujikura Ventus Black 9X

The TaylorMade M6 fairway wood that McIlroy was using during the 2019 season is still in the bag of some of the best golfers on Tour in 2026. Just check out Justin Rose’s winning setup from the Farmers Insurance Open earlier this year. This year, though, McIlroy has still been searching for his top-end-of-the-bag setup, having played both the new Qi4D and the Qi10, which he won the Masters with.

The same shaft swap can be seen in the fairway woods as the driver, along with slightly less loft on the 5-wood.
Irons
2019: TaylorMade P750 (4) Buy here, TaylorMade P730 (5-9), Shafts: Project X 7.0
2026: TaylorMade P760 (4), TaylorMade Rors Proto (5-9), Shafts: Project X 7.0

The biggest difference between McIlroy’s custom set and the stock P730s is the groove design. While the P730s were constructed with 14 MX-9 grooves on their milled faces, McIlroy’s proto heads instead use the higher-spinning, 16-groove layout of the TW2 grooves. Other big differences between the sets are that McIlroy’s 7- and 8-irons have thinner toplines, are 1 degree stronger in loft, and are 1/4 inch longer than the original P730 builds.
With McIlroy’s 4-iron, the switch from P750 to P760 sees a transition to a two-piece construction with Speed Foam in it, which allows McIlroy to launch the ball slightly higher, with more workability.
Wedges
2019: TaylorMade Milled Grind (48-09SB), TaylorMade MG Hi-Toe (52-09SB, 56-09SB, 60-LB09), Shafts: Project X Rifle 6.5
2026: TaylorMade MG5 (46-09SB, 50-09SB, 54-11SB, 60-08LB @61), Shafts: Project X 6.5 (46-54), Project X 6.5 Wedge (60)

Between 2019 and 2026, McIlroy’s focus on his short game has been much more apparent. It was the reason why he switched back to the TP5 golf ball, to help with launch, spin and control with his wedges leading up to his career Grand Slam victory in 2025. The most apparent changes to McIlroy’s wedge setup are his lofts and bounce. He’s slowly delofted his pitching to a sand wedge, but has increased the loft on the lob wedge, bending his current 60-degree to 61. With that, adding more loft to his lob wedge also slightly increases the bounce and leading-edge sit point, so, as a result, he plays a lower-bounce lob wedge compared to 2019. The MG5 wedges are also softer than the first Milled Grind option from 2019. McIlroy also no longer plays the full-face grooves found on the Hi-Toe.
Putter
2019: TaylorMade Spider X
2026: TaylorMade Spider Tour X

Notice anything similar. Yes, the copper finish on Rory McIlroy’s Spider X putter in 2019 is a slightly more reflective finish than the recently released torched PVD finish. McIlroy was using the True Path alignment system, but now uses only a single white sightline.
Ball
2019: 2019 TaylorMade TP5 (#22)
2026: 2025 TaylorMade TP5 (RORS)
As mentioned above, McIlroy had transitioned from the TP5 to TP5x golf ball since his victory in Canada in 2019, but now is black with the same style of golf ball as his victory at Hamilton Golf & Country Club.
Grips
2019: Golf Pride Tour Velvet Cord
2026: Golf Pride MCC
Interesting, McIlroy actually used Golf Pride’s Tour Velvet Cord grips during his victory in 2019 (it was during a 2+ year switch to the corded TV) as opposed to his usual MCC grips, which he has played for most of his career.

What is the lie angle on Rahms irons? It says they bent all the loft and lie on the irons and that the loft ended up a half degree weak but no mention of what they did with lie angle.
