So I practice putted with my proto fossil scale yesterday. First off, fossil is the best plastic blend from gateway. I love it. Perfect flex, perfect grip, it is grippy and velvety. The thumb groove is in an excellent spot. You can really tell that most of the weight is in the rim. I feel I can generate more snap from this. I also feel more comfortable from further out with the Scale.
This thing putts great. I can really trust the line with this putter. It always finishes the same. I did aim a little high right on longer putts, but even then the Scale is still easy to range. For me, I like OS putters. The scale easily fills that roll. I see this as my new putting putter.
