I was one of the early adopters for Super Stroke putting grips. I had been looking for a larger grip that I liked for a while, and those first SS grips were great. Eventually I migrated to the mid-slim (2.0) grip. All along however there were two things that bothered me about the SS grips - one important and the other less so. The important thing was the feel/texture of the grip. They got slick feeling with use, and never really felt refined. I even started keeping my glove on at times to putt. The not so important thing is I never liked the mostly white color - which seemed to start looking dirty by the second round of use.
Today I installed the one of the new Winn putter grips. As you can see they are longer than the SS with a taper at the bottom. The grip area profile is almost identical, however. I put on the 1.18 size which is just slightly smaller than the SS.
I certainly want to see how it feels over time, but my initial reaction is that Winn NAILED it with this grip - the feel is perfect. I especially like the different texture for my left and right hands. The left is very tacky while the right area is softer and smooth. I am always trying to deemphasize my right hand and this grip is a clear reminder to let the left hand be the primary connection to the club.
I also like the style of the grip a lot. We'll see if the grey area attracts dirt like the SS seems to do, but esthetically I greatly prefer the look of the Winn grip.
All in all the Winn is what you would expect from one of the premier grip companies. My guess is it will stay on my putter a long time, and my practice putter will need a change as well.
