I don't think supination works to applt THT,it tends to drop the bathead and
prevent the bat from swinging in plane.It is insted the external rotation of the
back arm(humerus/upper arm,not twisting of forearm) that is mostly
responsible.Prior to this,the back arm needs to be in position to externally
rotate by internally rotating with hip cock and staying internsally rotated as the
back scap pinches.Then THT can happen via external rotation while the back
scap stays pinched/loaded.This accelerates the bathead into plane,creates
reisitance that permits ongoing loading/coiling/keeping thehands back,and
does not push or disconnect the handpath.
