Have any of you tried a circular grip, or some kind of grip(the actual grip that is part of the club) that easily allows one to get the LEFT THUMB AFT when positioning their hands on the club.

If the pressure points are lined up along the sweet spot plane of the club... it should be of some advantage mechanically, even with putting. I think this would be especially true if using a PUSH TYPE STROKE, then the #1 Pressure Point has something to push against.

With conventional putter grips, the left thumb, if placed aft, would be resting on part of the edge of the flat top, that is a characteristic of most putter grips.
