In-hand photos of Bryson DeChambeau’s 3D-printed Avoda irons and his explanation of their “bulge and roll”



At the 2024 Masters, Bryson DeChambeau spoke publicly about his custom, 3D-printed Avoda irons, saying, “they have just got a different curvature on the face than other equipment. Most equipment is flat. These have a different curvature on the face that allows me to have my mis-hits to go a little straighter sometimes….when I mishit on the toe or the heel, it seems to fly a lot straighter for me, and that’s what has allowed me to be more comfortable over the ball.

Most equipment aficionados assumed DeChambeau meant that the irons had “bulge and roll” on the face, just like a driver, 3-wood, or hybrid does. On Tuesday at the U.S. Open, however, DeChambeau seemed to have cleared up the confusion.

While speaking with Golf Channel’s Johnson Wagner, DeChambeau spoke on the designs, and gave a demonstration of what’s really going on with the face curvature.

“[It’s got] roll on the face – well, bulge. Well, whatever term you want to use. But essentially it doesn’t roll this way (from the top to the bottom, a.k.a. “roll”), it rolls this way (from heel to toe, a.k.a. “bulge”). Can you guys see the curvature on the face? It’s kind of like a driver, or a hybrid, or whatnot…but it does cave in on the heel, and it caves in on the toe, as well, which creates that curvature. So for the speeds that I have, when I hit it on the toe or the heel, it doesn’t overcorrect. So, most people think that irons, MOI (moment of inertia) there doesn’t really effect the curvature, but it actually does at my speeds, at [lower lofts and higher speeds]. So essentially when I hit it on the toe, I was hooking it like crazy. Heel – I was missing it right like crazy. So I created curvature on the toe and the heel to get it to start it a little farther right on the toe, and on the heel, start it a little farther left, to make sure it doesn’t go too far offline.” 

Essentially, DeChambeau is saying that his irons are made with “bulge” on the face, which means they curve from heel to toe, but they do not have “roll,” which would mean they would curve from top to bottom. For DeChambeau, this custom face design helps his toe strikes start farther to the right, and then hook back, while his heel strikes start farther to the left, and then slice/cut back. Therefore, when his toe-hits hook to the left, and his heel-hits slice to the right, they are working back toward the target line, rather than starting on the target line and curving away from it.

DeChambeau also implies the curvature is greater on his lower-lofted irons, where he’s creating higher ball speeds. This would mean the “bulge” is progressive throughout the set, with more curve on the longer irons, and less bulge on the shorter irons.

On Monday, got in-hand photos of DeChambeau’s Avoda irons, for a better look at the face curvature and design of the irons.

    Some of these guys can win with anything. I get the logic though, it seems to have merit.

Highlights from the Wilson Golf Product Testing and Fitting Experience at Pinehurst



All new from Wilson Golf this year are Staff blades and CB irons, Dynapower Forged irons, Staff Model ZM wedges, a new golf ball, the RB Utility iron that was released just a few weeks ago, and the company’s own club fitting technology called Wilson Fit AI.

Yeah, it’s been quite the first half of the year for Wilson Golf. Wilson is serious about establishing themselves as a major player in the golf industry. They’ve made new hires, bringing on Markus McCaine (by way of Cobra Puma) as the Head of Global Marketing. Willie Mack, Padraig Harrington, and Kevin Kisner (to name a few), are playing their products on Tour. As we mentioned earlier, they’ve released a ton of new products. But, with all of that being said, how do these new products really stack up?

That’s where we come in. Wilson Golf wanted to reach the hardcore golfer. The equipment junkie. The person who tries everything to find the right fit for optimal performance. They weren’t looking for someone who already had Wilson products in the bag, who would have attended this trip and predictably said great things about their newest line of products. They wanted to prove how Wilson Golf, the brand, and their new products, can truly compete with the major golf manufacturers. With four lucky GolfWRXers in tow, we headed to legendary Pinehurst to meet Wilson Golf’s team of product experts, to test (and get fit) for the full 2024 lineup of Wilson clubs — and play not-yet-open-to-the-public Pinehurst No. 10! The four WRXers — @TLUBulldogGolf, @TM golf guy, @Shilgy, @Olson12— enjoyed a once-in-a-lifetime experience in North Carolina thanks to Wilson.

Members on Wilson Fit AI

TM golf guy: “The AI experience was super cool. 3 swings and it fit me basically exactly into what I expected.”

Shilgy: “The new Ai fitting tool is legit. First answer a few questions and then there is a fitting iron that measures everything. It’s almost scary how easy, and accurate, it is. Started me with a shaft that was too light but based on contact it changed to 115g DG. About as expected. I was fit into the CB with the Dynapower forged as the 5 and 6 iron.”

First impressions on the Staff Model and Dynapower irons

Olson12: “After warming up, Ed had me hit a handful of shots. It took maybe five or six shots, and we decided it was enough. Of the six shots, I hit four pretty well, one perfectly, and one really bad one. The app spits out recommendations based on all the data it collected and gives you both a steel and graphite option. On the graphite side, it went straight to the Steelfiber 110s, so that was the first one we tried. Ed built up a 7-iron in the Wilson Staff CB with the Steelfiber 110s, and we were off to the races.”

“I currently play a Titleist T100/T100s combo set with Nippon Modus 120x shafts. I bought this used set from a local shop after bouncing around a few different sets. (Thank God for the 90-day playability policy.) We’ve all heard the standard saying, “you want 1k spin x the number of the club.” For me, I’ve never even come close to getting 7k with my 7-iron. I’ve always hovered around 5500 and just learned to play with the rollout. My first few shots with the Staff CB were 7400, 7600, and 7100 with the Wilson Model X ball. Nice high cut, landed soft, PERFECT. Didn’t need to hit any other combos.”

TM golf guy: “I am currently playing i230s, and am generally happy with the performance. I had a feeling I would wind up with the Dynapower Forged, but I went in with an open mind to see what was suggested. After getting my numbers, Ed put together a Dynapower Forged with the UST Recoil Dart 105 F4 (stiff). It didn’t take me more than a few swings to know this was the set for me. I’ll do a formal review with side by side with my i230s later after I get them back and get more time with them, but I think these are going to be gamers. I was able to move them either direction, and they felt better than the i230 based on my limited experience so far.”

TLUBulldogGolf: “The MBs flat out perform, if you want that classic look they should be on your shortlist to try, they nailed the shape and the sole design and turf interaction were just what I expect out of a blade. The options to combo with the CB and new utility should appeal to anyone after that classic look with performance.”

Shilgy: “First swings warming up on the range and I could feel the difference, in a good way, between a properly built set and more mass produced. The balance of this set is fantastic. I’ve always been partial to heavier shafts and heads but the T150 always felt too head heavy to me. The balance on this Wilson set is perfect.”

“Suffice it to say both the CB’s and Dynapower irons were quite good today. Hit it solid and you will get the same result every time….miss it a bit and you’ll still get a very playable result.”

First impressions on the Staff Model ZM wedges

Olson12: “I currently play 50, 54, 60 Vokey SM9 wedges but decided to give the 58/6* a whirl, and I’m glad I did. I mentioned to the staff earlier that I never use my 60 for anything longer than 50 yards. I’ve never felt comfortable with a full swing lob. Going to the 58* gives me more confidence on full shots but was still able to hit all the chips and bunker shots I normally hit with my 60*.”

Guys… These are fully forged wedges for $150. I just ordered my three Vokey wedges a few months ago for like $600. What the hell, man! If you are in the market for wedges, do yourself a favor and just give them a shot. Nice traditional shape and a super soft feel. Not too clicky but still gives audible feedback on mishits.”

TM golf guy: “The Staff ZM wedges were something I was really interested in as I loved the head shape, and the feel and performance didn’t disappoint. They have a really nice shape to them, and the sound and feel is also excellent. I’m a big fan of the 60° that I got. The grind really allows for a lot of versatility around the greens as well. My only regret here is that I didn’t get the Staff gap wedge instead of the Dynapower one.”

TLUBulldogGolf: “The wedges are really solid as well, I feel like I can flight them with ease and they spin like crazy.”

“I have the 60-06 and it’s similar to a Vokey T grind, maybe a touch less demanding. The 56-10 plays very similar to a Vokey S grind.”

First impressions on the utility irons

Olson12: “I’ve played Srixon & Ping Utilities for a while now. I recently gave up the Crossover and went back to a 3 hybrid because the offset was just not working for me. Since the club was just announced today, we had just the stock HZRDUS Black shaft in both the 3 and 4 iron. I hit the 3 and realized it’s been a really long time since I hit a long iron. It took a few swings, but I started to find my groove. Minimal offset, satin finish, and a good-looking topline. This thing is going to compete with the big boys. Hell, @TLUBulldogGolf was getting 150mph ball speed when hitting it off of a tee.”

TLUBulldogGolf: “The utility is the real deal, just seems to want to go straight. A little longer heel to toe than my T200, and it just feels easy.”

The utility surprised me, I knew it was good at my last range session but it seems to come off lower despite having more loft than my T200. I hit it over the green from 240 on a par 5 which shocked me. The stock HZRDUS 4G stays with me and seems to be a good match for my irons.”

TM golf guy: “This utility is stupid good. The first swing I made I hit rather toey, and it flew straight as an arrow. Off the tee it’s a more penetrating flight than my Srixon, but still has good height. Like @TLUBulldogGolf said, it really wants to go straight. Definitely a winner.”

GolfWRX Members on Wilson Golf:

TLUBulldog: “They want to get everything on the golf side right.”

“I came away super impressed with what Wilson is doing and the direction they are taking the brand.”

“I’m hoping this (and their overall strategy) can up their visibility because the new product is legit.

Olson12: “I’ve been really impressed with the quality of the Wilson product. What stands out the most is the people behind the scenes. This group of people is IMPRESSIVE. They love golf, they are competitive, and they want to compete with the best of the best. I’m thankful to be part of their story, and once we get the full set and get a chance to play them out in the wild, I’ll be able to give a more thorough breakdown.”

TM golf guy: “They are a group of super passionate people who absolutely love what they do, really have a lot of great ideas, and are a really cool group of people to talk to (they also know their way around a golf course!). They were incredibly open to feedback, and were also very candid about their thoughts on things as well. The people a company chooses to represent them says a lot about the company, and Wilson has picked an incredible group. I think Wilson has an extremely bright future ahead of them, and they’ve certainly made a fan out of me.”

Shilgy: “We all definitely need to add Wilson golf to our must play equipment. You’re definitely doing yourself a disservice if you don’t at least try them out and with the new AI fitting tool every fitter out there can be a Wilson expert fitter.”

Shilgy, Lindsey Lasater, TM golf guy, Markus McCaine

One final thought

If you’re in the market for a new ball, a hidden gem emerged during this trip. Our members were impressed with the new ball from Wilson. Coming from the Chrome Tour X and TP5, Olson12 stated that the feel of the X around the greens was “pretty damn good.” While TLUBulldogGolf shared, “I’m liking the Model X. Very natural transition as a V1X player.”

We’re looking forward to diving even deeper into the trip and what Wilson has to offer over the next few weeks. In the meantime, don’t hesitate to follow along in the forum.
