A good amount of #2 helps with making sure that the hands get a nice headstart, giving the sweetspot something to chase! As for the grip, 10-2-D seems to be knuckle neutral for me, but my left hand is not quite 45* turned. I cringe at the years I spent trying to weaken it, when based on preliminary results I should have strengthened the right hand. Again, thank you Edz. Tough to get your right forearm anywhere near on plane with a rolled right hand. It also does not help with the RFTA. I turned it a smidge and I could immediately feel my right elbow respond. So the right forearm responded to the alignments of the hands. I feel the RFA pickup a little better. Feels uncomfortable the longer the shaft, but I think it is going to help.
Jerry, I big aha for me was learning the the right shoulder is the liason between the power package and the pivot...train it!
