Martee,
I can't really explain the concept of the left wrist facing the plane- as it is not one that I use or originated. Nor did Homer use it in the book. Are we talking about the left wrist/palm exactly parallel to the plane?, or just a general term of generally facing the plane? Of course, that would apply with hitting also- the left wrist facing the plane. Does the hitter or swinger have their left wrist/palm facing earlier or later than the other? Depends on the player and his pattern. Generally speaking during the takeaway for a swinger who is setting up momentum in the club by dragging the club back- you're not going to have much rotation of the forearm at that point, until the hands slow down and the momentum of the club continues- and rotates the left wrist. The hitter would generally have rotation from the very beginning, created by the body/arm motion- not an independent or conscious rotation of the forearms. Likewise, the swinger doesn't conscious rotate his forearms but that occurs as a result of centrifugal force, anotherwords your loading actions and acceleration methods determine your wrist actions in the ideal situation, for both hitters and swingers. That's just part of understanding the individual components of the Golfing Machine and their role in relation to the broader concepts in the Golfing Machine.
