With fear and trepidation, I venture to ask a question about hinge action. Forgive me Daryl if this is the wrong thread to ask this question!

Can some one describe the relationship of the right and left arm flying wedges to hinging? Is hinging another way to describe the movement of the arms from impact to end point (both arms straight)?

I ask this question because, given the discussion in this thread, it seems to me that hinging is much complicated than simply the closing or the laying off of the clubhead through impact. I have heard many people talk about closing the club face, e.g., by rolling the forearms or rolling the wrists, but those "methods" don't seem to be getting at hinging, or at least, not at a full description of what is going on with hinging mechanically.
