Thnx - I'd welcome that and whatever interpretation you can add.
In his clip at
http://www.lynnblakegolf.com/gallery...Chapter3BB.wmv Tomasello is pretty clear about hips following the trail elbow. Even though he states they should be kept back, I'm sure the feeling and intent is to make sure the hips follow rather than lead.
I think his major point is the student he is addressing needs to lead with with trail elbow and arms into a hit with the clubhead past his left hip to get a horizontal hinge action with the clubface.
Tomasello is pretty clear that early hip action will turn the shoulders and lead to 'over-the-top' faults.
