Gentlemen, fellow Stankbutts , I sense ndwolfe's question remains unanswered.

Namely, given the advice to take the right shoulder down plane or at the ball in Start Down, should the right shoulder (shaft , right foremarm) be on the inclined plane at impact? Any amount of #3 angle or right arm bend would make this impossible no? What gives?

Unless you do something really strange duruing a full swing- the right shoulder would be on plane during start down but obviously at release and impact it is no where near the plane.
