My thanks to JR for that easter egg on "forward press"......never thought of it in that way, having learned golf in the golden era of the "Hands Only" Forward Press.
Great post again O.B. If I may add one note.
This first few feet of Hand travel in Startup which J.R. describes, a travel motivated, produce solely by the Hips clearing from their Fix position: Some would might say "Ah, but surely that's Pivot to Hands".
To which I would say; "Not necessarily, Buster. IF you're Tracing, with your mind in your Hands .....its still Hands to Pivot".
The same deal happens in Startdown when the Pivot takes the Hands Down the Inclined Plane for the first wee bit. The Pivot may be driving the car but the Hands are back seat driving, directing.
