This may be in the ball park of what I'm looking for, I read your post and tried a few backswings in my living room and moving my hip behind me seems to creat a ton of room as wellas allows me to keep my height with the lead shoulder.
Ill try tomorow while practicing and update you
Thanks
My instructor has me working with 10-15-B Delayed Hip Action with pre-turned hips at address. They're not turned all the way through but get naturally "picked" by the shoulder turn in the backstroke.
