Bagger - I realize that one can choose not to have roll action (horizontal hinging) during the followthrough phase of the swing and that one can instead choose a non-roll action (angled hinging) or reverse-roll action (vertical hinging). However, I am interested in the biomechanics of left hand "roll" in the horizontal hinging action and in learning whether the left hand "roll" of horizontal hinging is any different to the left hand "roll" that occurs moments later during the finish swivel action, or whether they are a seamless left hand rolling action (occurring due to different biomechanical actions at different anatomical/biomechnanical levels).

I look forward to learning more from your "new" Jeff Hull swing video - when it becomes available.

Jeff.
