Hey folks. I think you are making this way too complicated. Isn't the answer that you do lift your arms slightly but don't use your arms to bring the club and shoulder back. Just think of the drill many of have seen to set the club properly. The one where without turning your break your wrists and then throw your club over your shoulder. Then, in that position, one simply roatates the shoulders back to demonstrate where one should be at the top of the back swing. I submit that the move where one throws the club over the shoulder cannot be done without lifting the arms. Can some provide a link to the video of that drill so our Goldfinch can see what I am talking about.
Never mind. Go to this site Goldfinch and take a look at the right shoulder drill.

Your turn back should be done almost entirely using the shoulders but once you get your arms straight back you should cock the wrists and lift the arms a bit. To what degree I am not sure but that drill is I think gives you a pretty good barometer.
