The Rotated Shoulder Turn (10-13-C) can locate a Turned Shoulder Plane, but only if the Waist Bend is exactly right. I wrote a post a couple of years ago describing one way to determine the necessary amount of bend (and it's a lot). [Search my posts in the Archives for Rotated Shoulder Turn; I think I called it Shoot the Plane Line.]
Remember though, the true Rotated Shoulder Turn (in both directions) is effected by a Shiftless Hip Turn (10-14-C). This produces a Low Power Stroke that limits its usefulness to Short Shots.
That's what I was getting at,maybe I should have asked "what do YOU [Anders] mean by rotated shoulder turn" .
I found when trying in vain to use this turn -on good shots it was actually an on plane turn on the way down.I found it was impossible to stay on the Rotated plane and hit the ball with any power
