Trackman sounds really interesting. I believe landing angle is important too. What you'd want will depend on your swing speed and the kind of course you're playing. You wouldn't want a shallow landing angle if you're a 120+mph guy playing at St. Andrews.

But I'd like to reinforce my headwind argument. Most drivers are fittet for max carry in no wind conditions. But when do we need distance the most? With the wind in the face of course. Besides, on most courses a little less carry will be easily negotiated with a lot more roll.
