This Mizuno Japan site shows JPX850 and JPX900 adapter is also used on MP Type 1 and 2 driver heads

I just did experimental shafts with my gamer head. So no additional $. That way if it works, still playing the head I know. If it doesn’t work, one adapter screw loosen and I’m back to my gamer shaft. I did invest $8.99 at Billy Bobs for a couple different head weights to swing weight, but can also use those regardless of shaft

The X flex Diamana allows me to swing pretty vigorously on course (106-107 CHS, usually get maybe 260 carry, lots of fairways in Phoenix are harder except after overseeding, so get maybe another 10-15 yards roll). I developed sudden lower back issues about 10 years ago, so am always looking for same/more distance easier swing. That is what intrigued me about DIY Otto-phlex. I’m always having to tell myself “ it’s technique/sequence, stop trying to swing so hard”. So the motivation to avoid further injury is what allows me to transition into a Otto-phlex type swing easier than someone looking to just pick up yards. My long term ability to play depends on it. I was somewhat skeptical waggling club on my initial 9 hole trial, but as others have said, Grafalloy Prolaunch Blue 45 A produces surprisingly accurate start line and lateral dispersion. Must be stable. 6 of my 7 drives (forgot my GPS watch so eyeballing) were either even or 10 yards ahead of where I usually am (albeit 1 hook which isn’t unusual), and other drive must have rolled in water on par 5 at end of fairway because we couldn’t find it on straight drive (#15 at Ken Macdonald, maybe @azstu324knows that one). So I consider the experiment on a 1/2 round sample size a success. The 75-80% / concentrate on sequencing swing seems to works like others have found. Thanks everyone that blazed trail before me. I did put a light R flex (1-2 flexes down) Evenflow Riptide Blue in my 5 wood but getting ballooning, high spin , short shots. Will have to evaluate what’s going on, but that won’t affect my driver experience.

Currently have the 45g A flex at 45.5” @ D1 in my SIM as the experiment. Was playing a Diamana S+ 65g X flex at 44.25” usually

Anyone have any hands on experience comparing the Grafalloy Prolaunch Blue 45g A and L models against each other? Thanks!
