Could you describe (roughly) what the proper shoulder-to-hands alignment feels like at the top/end? Does it feel like there's a "connection" between the hands and the shoulder? Do you know what I mean?

Sure.

Approximate the left arm by looping a 4-foot cord around your left shoulder and stretching it with your right hand. Swing the stretched cord to the Top -- right shoulder high and On Plane -- with your right arm.

That is the Mechanic.

And that is its Feel.

I wrote a post recently for DrewitGolf with an idea for a TV teaser spot on exactly this mechanic. I'm having trouble finding that post, but when I do, I'll link it here. Meanwhile, if anybody beats me to the punch . . . Thanks!
