Spotted: Three new “Mizuno prototype” drivers hit the USGA Conforming Clubs list
The USGA Conforming Clubs list is always, always full of surprises. As of September 1, three new Mizuno Prototype drivers appear on the list.
The most notable part? The switch from blue to black.

Unfortunately, this could be a future Japan-only release, rather than made for the U.S. market. Tour Spec Golf, a company devoted to high-end JDM golf gear, has “in-hand” (on ground) photos on its Instagram account. While that doesn’t necessarily mean it’ll be Japan only, it just might be best not to get your hopes up.
But alas, here are how the clubs look on USGA’s conforming list.
Mizuno Prototype Version 1.1


Mizuno Prototype Version 2.1


Mizuno Prototype Version 3.1

What do you think of the new clubs? And why does the #5 appear on Prototype Version 2.1?

Interesting clubs at top of bag – GolfWRXers discuss
In our forums, users are talking about top of bag setups that are non-traditional or thought-provoking in some way. Original poster @SuperSpurs106 inquired about other members who might use unorthodox set-ups to help with gapping issues or weak spots.
They wrote:
“I currently have a PING G430 driver, TM Qi35 3W and a TM Qi4D 7W. Driver and 7W are fine but can’t get on with my 3W and have always struggling with this club over the years. Thinking of adding a 2H which I know would look odd. Just wondering if anyone else had a weird set up at the top of their bag?”
Our members in the forum have offered up their thoughts and personal experiences with non-traditional top of bag set-ups, and their reasoning for thinking outside of the box to begin with. 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.
- BowMain42: “Don’t worry about what “looks” odd. If the club does what you need it to do, it’s the right club.”
- scooterhd2: “I cant hit 3 woods either. Thats why I roll with a unicorn XL Hibore 2 wood. 400 cc head at 16 degrees of loft and its just a monster 3 wood off the tee. Off the deck, we are playing the f6 baffler. 5 wood at 41.75 inches and its easy to control.”
- phizzy30: “I had driver, 3 metal, 2/4 hybrid once upon a time as a higher ss player. 4 hybrid is gone and in place is a driving iron nowadays. I don’t think what you’re proposing is weird in anyway, however the yardage gap might be glaringly huge between driver and 2 hybrid. What is it about your 3 metal that has got you all messed up? You could always go 4 metal with shorter shaft and see if that works.”

Members of the Mini Driver Club – GolfWRXers discuss
In our forums, one user has gone searching for fellow users of a mini driver. In a post, @TightFade asked for other mini driver users to chime in with their weapon of choice, the reason for employing a mini, and what club follows it in the bag.
@TightFade asked:
“What mini are you playing? What spot in the bag did it take over? What’s the next club after it? For me: Elyte mini 13.5. Replacing 3w. Next up club looks like it’ll be 5w.”
Our members in the forum have been sharing their own bag setups featuring the mini driver, and the various reasons they purchased one in the first place. 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.
- RCGA: “Ping G430 Max 12* ‘Thriver.’ Next club is a 4w and 2i (I play a weird course).”
- JMB3: “R7 at 12.75 with Diamana BB 63s. 3w replacement. Next Club: Elyte Ti 5w at 17*.”
- ColdOkieGolf: “R7 15.5 turned down to 13.5 It replaces the 3w. I found it surprisingly easy to hit off the deck, and it’s very rare that I need or want to hit something beyond 250 from the fairway, so next club is my 7w.”
- ChaosTheory: “I’m sub-90 MPH with driver. But I’m able to hit DOD. I have been wanting something like the R7 15.5, so I just ordered one. I have a spot in the bag so nothing has to go. But I could see it replacing my trusty 4 wood, which I never use for approach shots. Just tee shots and lay ups. If I drop the 4 wood, I will turn my 7 wood down to ~20 degrees and will have good gaps. I recently tried a thriver build: 12 degree driver turned to 14, with a heavier 44 inch shaft and added head weight. I hit it great. Very accurate and not overly high, but the problem was that it sometimes went as far as a typical drive. And that’s not what I needed. So I will probably turn the 15.5 up to 16.5 or even 17.5. It’s all theoretical at this point. ?”

Would be strange for a 3w and 5w to have adaptors that say 8.5*. Definitely three different driver prototypes.

Who wrote this article? The pictures obviously show a driver and 2 fairway woods. Not 3 drivers.

I’m guessing that it’s because it’s a 5 wood.

Well, if you hold prototype 2.1 upside down and in a mirror, that 5 might just almost look like a 2…
