Sorry I re-read the statement in bold. I'm not sure I know what the heck it is saying. But all I'm saying is that it could be argued that 10-2-D could be a better grip for some than 10-2-B due to reducing the variable of Swiveling. I think Mac O'Grady actually was a proponent of this.

Mac O'Grady suffered from over acceleration issues in the downstroke which leads to loss of club head lag which means the shaft and club head is doing funny stiff closing coming into impact. The stronger left hand grip will help negate the effects of this but really we should all be striving to maintain and sustain club head lag rather than building in modifications to deal will the loss of it in the downstroke . Keep the swing on plane in the downstroke, have a flat wrist at impact and sustain club head lag past the ball until both arms are straight and there is no left shot. IMO that is the real anti left way of doing things .
