The shoulders are points . they do not move independantly. Build a solid structure- sure extensor action is PART of the assembly but the structure in its simplicity WITHOUT ADDITIONAL HINGING OR FLAPPING ABOUT PARTS, all moving with their LIMITATIONS of range. That is the feel of mass that gives the wrists FREEDOM to operate from. We are tought by those far wiser than myself that golf is a feel not a ... whatever. I think this is most important and untill it is grasped "NOTHING ELSE MUCH MATTERS".

I agree. However, the Power Package is best assembled and guided to the Top of the Swing under the Push-Force of Extensor Action. EA ensures that the Flying Wedge Alignments (for those that assemble at Start-up like me) remain aligned to the Top/End of the Swing.

Anyone can sense the Alignments, but with Extensor Action, adjusting the Alignments can be easily nursed. And I mean that we all Plane-Shift during the Backstroke, which requires re-alignment onto the Turned Shoulder Plane at Transition, before Start-down. It's not only the Clubshaft, but the Power Package that needs re-alignment. Leaving your hands at the Top is a good substitute, but I'd rather use the technique simply to increase shoulder lag because the Pivot is already responding to the #3 PP pressure.
