I have the Gauge Design M3 AL US spec 1/500 1st one of 500 made. This is the putter Shingo Katayama is currently using. I found it at a Japanese importer golf shop along with other great Gauge Design putters. This one is MOI design and has a super long sight alignment line even longer than Bobby Grace MOI 6.4K which I previously used before the M3 AL. Before that I played Baby Bee proto. So, I'm not new to these new tech moi design putters. I've always been a great at putting. But this M3 AL makes sinking puts easy.

I really thought there won't be any putters that'll replace Bobby Grace MOI 6.4K but with extensive putting comparison trials, M3 AL simply had much better feel, accuracy and distance control. Due to the location of the MOI weght placed way in the back and high above the center median of the golf ball, the ball when hit rolls with top spin and truly straight. The consistency is incredible. Ya can't miss with this putter.

For people who are used to blade putters, give this one a try because unlike the bulky design of Baby Bee and Bobby Grace MOI, this one has the conventional blade like putter design with super sight alignment and moi weight attached to it so it seems like you're hitting a regular putter. Seriously, once you've tried this putter, you really can't go to any other putters. This one is a winner. You have to be a serious moron if you can't point and put straight with this putter. Good luck finding it though.
