doug, the sad thing is I went back to a conventional putter and have been mediocre all season. I had trouble with the belly gaging the speed on very fast greens. The first time i put it in my hands, I thought I had found "The Fountain Of Youth." Maybe I will bring it out of retirement. The greens at Southern Hills won't be that fast for the PGA in August, so the jury won't be out for Sergio and his bellyputter until the Masters next April. Good Luck
