Saw some other threads about the Super Stroke grips. I just put one (mid slim 2.0) on my Scotty Del Mar and love it!! I stuck with the Scotty "Baby-T" grip for a long time, but thought I'd give this one a whirl as it was time to regrip anyway. I am normally a good putter - what separates my good rounds from okay rounds. I average about 26-28 putts a round and hope this one will improve that :)! I am not sure I would go with one of those fatter ones... What I like mostly is the absence of taper. I was going to try the "pistol" one Scotty has, but the transition from top to bottom was to great. Felt good in the top hand, but like a #2 pencil in the lower and I got "snappy" when I tested one out. Since our greens were recently punched, I have yet to see it a whole lot on course, but my green at home is Augusta fast and it works great. I did take it to another courses practice green and did quite good on a ~10.5 speed green. Slower greens, not too sure about, but thankfully I don't play on many of those.
So I would recommend trying one out! I would start with the smaller so it is not too drastic of a change. Plus, there are no screws, etc. that I read about.
