lynn do you purposely not have much hip and shoulder turn in this stroke because it is an acquired motion.

Whatever has to move, bantamben, moves. If it doesn't have to move, it doesn't.

The Hands dictate (the alignments).

The Body complies.

That said, because of the camera angle, there is more Turn of both the Hips and Shoulders than meets the eye. Compare the first row of frames (1-3) with the fourth (13-15).

But the real key is Downstroke Pivot Lag.

My Hips Lag my Shoulders going away, and then my Shoulders Lag my Hips coming through (Delayed Hip Action / 10-15-B). The Downstroke differential between the Leading Hips and the Lagging Shoulders -- specifically, the Right Shoulder -- creates a Pull that Loads and then greatly assists the Delivery of the Power Package Down Plane to Release (6-B-4-C). From there the Swinger Throws Out the Club with Left Wrist Uncocking Action (10-20-E) and the Hitter Drives Out the Club with Right Elbow Straightening Action (10-20-B).
