Normally I'm about 1 full fist above the bar. With knee hangers on the T2 I found my self about 4 fists high. It felt high but the bar was still in easy reach. Never had a problem doing this on the Sport or Falcon. Everything was fine until I brought up my speed on downwind. I induced a significant oscillation. The pendulum length, roll authority, delay on the stiff glider; all enough to cause an "oh, shit" moment.
Moral: Hang height is more important on stiff gliders.
