Aft CG for torque roll / hover
As a mental exercise, imagine a bowling ball on a broom handle.
Would you rather try to balance the ball stick combo with the ball at the top of the stick or bottom?
It's not an absolute correlation, but it seems to work the same for airplanes also. If your wing isn't working anymore, who cares how aft the CG is as long as you still have control.
I find I can TR MUCH easier with planes that have the CG so far aft that they're either climbing or diving with very little elevator imput during "normal" flight. No fun to fly around this way, but noticeably easier to horse around once the wing isn't working anymore.
