Thanks. very helpful. Still there is the issue of whether in fact the first move of the right shoulder is 'quick' or rather that it does not have to be slow (as it must be for the hitter). And the first direction the right shoulder takes (as a result of the left hip bump) is down and if that is right it is not a flywheel action of any sort, or so it seems to me. The flywheel action occurs as a result of the pivot action I take it and that comes after the weight shift. So it seems to me there are two moves that the right shoulder makes -- one in response to the hip bump (right shoulder down, also causing the axis tilt); the second is the flywheel as a result of the pivot/rotation. So even if the flywheel is quick motion it does not happen first. The right shoulder drops on plane first and does not spin -- though I recall seeing Lynn Blake referring the right shoulder spinning at the start of the downswing (in a swinger). I thought I saw that in one of his videos and I recall reading in TGM that the right shoulder moves quickly in a swinger at the start of the downswing; and that is the source of my confusion. For it seems to me that if the downswing starts from the ground up, the first move of the right shoulder is down the plane; and only then can there be any 'spinning' at all.
Am I mistaken? I am open to learning that I have this all wrong.
I am one of those golfers who isn't happy just having good swings; I have to feel I have good swings for the right reason; and I have to understand that I am doing it correctly. I am sure that this is a minority view as for most people good shots are reward enough. I wish I had more good shots of course, but I crave full understanding (or as close as I can get)
