I actually think there are plenty of good swings where the head moves, but I see more good swings I like with a fairly centered head... Isn't it about what works for each student? When someone starts screaming from the mountain tops that a "feel" doesn't pass scientific muster I run away, and will continue to do so...

Can you imagine trying to make Bubba Watson swing like any template? I sure can't. Centered works for me though, and am seeing a lot of success with teaching my students a centered pivot. Things move when you see them in 3D, but that doesn't change the "feel" or the goal of getting on top of it...

Good stuff Kevin, the head moves even when you feel that it does not. I have a tough time getting my head back to impact fix once it has moved too far to the right. I set my head at impact fix, move everything else into an adjusted address and usually don't think about it again. Works better. Also, when the head is still on my backswing, my pivot is more efficient. Check out some youtube videos of Robert Allenby, that is the head motion I refer to.
