At the WGC-Mexico event this week, we’ll see something never seen before: Mitsubishi Rayon graphite iron shafts in play at a Tour event.

Roberto Diaz, a native Mexican who’s currently ranked No. 5 on the Web.com Tour money list, is using the company’s OT iron shafts at the Club de Golf Chapultepec. He was fit for the shafts at True Spec Golf in Miami, an international club fitter with U.S. locations in Florida, New York and Ohio. True Spec Golf also built his irons.

Golf Shaft-Type Overview_OT-1

The shafts originated in Japan from the Mitsubishi Rayon “idea lab,” also known as FRANKI (the Japanese word for incubator is “Fooranki”), and they are produced with a process that’s similar to how steel cables are made.

Each OT shaft is created from graphite fibers that are arranged in super-strong bundles and impregnated with resin to create the company’s special “Tow Prepreg.” The bundles are then woven together like a braid. According to MRC, the manufacturing process makes the shafts more resistant to twisting and ovaling.

Diaz is using a 105-gram model of the parallel-tip shafts in X-Flex. He’s also using an MRC Kuro Kage XT 60 (TX-Flex) shaft in his driver.

Seems as if OEMS are getting (hard to call graphite) as it seems there are so many other materials in the actual materials being used to get these shafts to a point of finally satisfying what a player wants from an iron shaft. I had weight issues with a few in past, meaning didn’t follow weight as standard steel shaft irons did going from long iron throughout shafts weighted differently didn’t correlate. That being said there are a few manufactures who have nailed it, at least IMO. I play Fuji MCI-100 limited blacks stiff tipped to stiff plus-ish. I played x100’s previous for longest period of time after trying most iron OEM’s offerings. i.e. KBS C-Taper, Tours, assorted DG’s (still love x100, in black onyx are even better) , Nippon; actually really nice etc. I believe some will be very satisfied the difference a few years has made. I’m not crazy swing speed player either. (105-108) 43.5 driver. I was assured by a great player/player these would be last iron shafts, at least for a while…he was right. Later releases and development may surprise you, give a try.

Slab city on the Korn Ferry Tour — Lead Tape Report

This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.

Joel Thelen

Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.

First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.

Mitchell Meissner

Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.

In our forums, one user has offered up a prompt for the true sickos, inviting fellow forum members to share every set of irons they’ve ever owned. As to be expected, this is a lengthy forum topic.

@Lamosteve began:

Can you name every set of irons you’ve owned? Here’s mine

Spalding Dots
Spalding Eclipse
Ram Lazer FX
Lynx Parallax
Mizuno EZ Comp
Ben Hogans
Cleveland CG Red
Taylor Made R9s
PING i20
PING iE1
Taylor Made M6

Our members in the forum have been offering up their own collections. Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”
JimmyC59: “MacGregor Jack Nicklaus Triple Crown. Palmer The Standard. Still play these.”
