If the left shoulder controls one of three hinge choices (horizontal, angled or vertical), help me understand *Dual Hinging*. ?? Is the 2nd hinge pin in the left wrist? (Edited additional info: In section 2G, 7th paragraph "Dual Horizontal" and "Dual Vertical" Hinging are mentioned "relative to Clubhead Travel. As I re-read this, I presume the dual reference was to backstroke turn & downstroke rotation??).
