I need to make a "Fine Point". It's pretty advanced but I think everyone can handle it and not lose sleep tonight. "Swiveling" and "Turn and Roll" are not opposites nor are they related. "Turn and Roll" is one concept, separate. "Swiveling and "Hinging" are related. They are Two different ways that the Clubface moves through the impact interval. Hitters Only Hinge. Swingers use a Hinge and Swivel but its not a Hand Swivel. Swingers use a "Release Swivel" whereby as the Hands move down Plane during the Pulley, the Clubface moves from On Plane to Vertical at Low Point. This Swivel is compatible with Hinging whereas Hand Swivels are not.
I lost sleep;
"EXACTLY", the best you can put it into words. Where does the "release swivel" occur for the swinger?
