To turn or not to turn, that is the question...

I'm trying to resolve what sounds like conflicting guidance (not necessarily from Tom) in the words "rotate" and "turn" VS shifting weight towards the target. Should I be turning my hips but keeping my shoulders on a line to the target? Is that anatomically possible? In general, it seems that when I rotate my torso, my shoulders open up prior to contact, my orientation to the ball changes and I make contact with the ball from outside the arc (your "dead zone").
