Bear in mind these launch monitor geeks tell me you can get lower spin rates and better trajectories when the Clubhead is going up during Impact.

Long before the advent of launch monitors and long before 'hiting up' with the Driver became all the rage, Homer Kelley had it figured out. He said that when the ball is struck after Low Point (the geometrically correct way to 'hit up'), there is less Compression Leakage due to backspin. The ball goes further, yes, but the trade-off is that you have less control.
