New Putter?

I have been seeing Greg and others putting with harder plastic putters, rather than the gummy one I have, so figured I might want to try one as well. I had seen/heard about this Discraft putter (174 gms) with a ring on the top for your thumb and thought it was a good design - and so decided it was the one I would try. I am not sure it will ultimately replace my trusted gummy, but it seemed worthy of experimentation.
