I have the face balanced model, which I haven't been able to try on the course for a month due to certain physical issues, but I hope to try it Monday. I haven't used a face balanced putter since I bought a Zebra in the mid 1970s, so if this putter doesn't work as well as I hope, I'd be inclined to mess with the weights.
I'll be interested to follow this thread and see what people have done.
