I agree you must keep the left hip turning, but don't discount speed of the action. It is the speed that activates the strech - shorten cycle of effective pivots. For reference, please check out Chris Welch's kinetic link work on the net. If you can't find it, our man Bucks has the link!

That stuff is really good with regards to generation of angular velocity . . .
