garyt1957 Gary I've been practicing and playing with the SmartPutter it's a much better way to putt for me the set up is the key along with the grip. There is no anchoring and it's a SBST stroke. Legal for all USGA and R&A.
I have used over the year a number of face forward putters. Positive Putter, reverse shafted Nivieus 400g long length and The Wonder Putter forerunner of the SmartPutter.
