Spotted: Prototype Mizuno driver on the LPGA Tour

This week, GolfWRX was out at the LPGA Tour at the FM Championship to get some WITB photos from some of the players there. We know the LPGA players always have some very cool club setups and clubs in their bags, and this week they didn’t disappoint! We spotted Jiwon Jeon with this prototype driver from Mizuno in the bag with very minimal markings other than the “prototype” text near the front weight.

This new driver features three weights on the head for a good amount of adjustability. There is a weight up near the face that we would believe can be used for reducing spin when you add a heavier version there. Mizuno has added a weight far back in the head that is usually used to increase launch, spin, and forgiveness when you shift a heavier one to that spot. The final weight is down near the hosel, very close to the hosel screw, which has been traditionally used to help the play rotate the face closed at impact and get the ball started off on a more left line.

This prototype looks to be using the same Mizuno adjustable hosel system as the current driver, but the numerals “o131” are printed there. I don’t know if that is a version number or has some designation on the loft or other specs of this head. Mizuno looks to have pushed some weight back in the head, as you see that extension on the sole at the back of the head. We have seen this done on other drivers, and it is usually to help with aerodynamics and pushing weight low and back on the head to optimize stability.

From address, this prototype looks clean without any markings or alignment aids on the crown. The shape to me is a little different from the current Mizuno drivers, as the back looks to be a little more tapered and less round. The current ST models look more round and bulbous to me, and this looks a little more traditional when compared to other brands. Mizuno isn’t sharing any details on this one yet, so everything we are going on is just speculation, but it could be a good look as to where Mizuno is heading in their next driver line!

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.”
