I found that very interesting. I'll defer to the rules guys on here but I can't think of anything in the rules saying you need to dry your clubface if it is naturally wet. I suppose you couldn't use a spray bottle of water any more than you can use vaseline, WD40 or 10W40.
When I say "as one" I mean should you rotate them both at the same speed, so that they both will match up in their rotation on the backswing?
Reason I ask is because since the spine can rotate more than the hips, should the spine be rotated more quickly - or should you rotate them at the same pace, then when the hips reaches it's limit, keep rotating the spine until it turns 90* while the hips stay in the fixed position
Here's a pic of what I mean, you can see his spine is rotated far more than his hips, because the hips have reached their limit
