More waist bend (as determined at Fix).

Yes Sir.

That's how you get the lower right shoulder. It starts at impact fix with enough right arm bend to accomodate both arms straight at follow-through.

Then take that to adjusted address without moving the right shoulder "up plane" any more than needed for your shoulder turn.

To me, it feels like a little "crunch" of the right oblique muscles at adjusted address, which creates a little axis tilt to keep the right shoulder down and right forearm more on plane. Oddly, dropping the right forearm on plane at adjusted address will do the same thing.

Since my right shoulder creates my biggest swing flaws, I'm very aware of getting it positioned right from the start. When I do it right, it feels like I've hit the ball before my backstroke even starts.
