sdandrea1 I've got the Ping G5i putter I bought new the year they came out. Yes, I've tried others just for S&Gs, but this will never be 'replaced'. Only have 1 other putter in the house right now. Well, 2 if you count that old brass Austad's.
Some of the Pros do go with newer putters(and tech), but most of them revert back to their old putter after a while.
They know. The deal.
