Especially for golfers who get yippy on short putts, it can make a difference. Where they have trouble is on longer putts, because you don't have the same feel for pace.

When we got down 10 or 12, I knew we were in trouble.

The early (1960s) classes are the ones we're having the most trouble with.

Our pressure got to them. Our press caused them some trouble.

I don't know why, but we were really flat. We had trouble again with turnovers and with rebounding. Those will hurt you every time.

I used one for about two years, and when I went back to a conventional putter last year, I found that I regained my stroke, especially on shorter putts, as a result of using the belly putter.
