TSP limits the amount you can load PP#4, which takes some 'mass' out of the force created and lessens #3's transfer power.

Agreed that it is easier to master (a left hand karate chop to plane, focused on #2).

In a nutshell, TSP is less powerful, but more accurate.

Kev - a flat downstroke turn creates too much 'out', and makes it difficult to stay on plane.

Ed . . . why do you think there is more accuracy inherent in the TSP? Not sure I'm ready to buy in . . . interested to hear your rationale.
