Any wing LE shape within reason can be forced to snap or spin. The larger LE radii require much more elevator to initiate. To me, more throw is not whatI want to produce the same effect

That's the reason I like sharper LE's on the wing. Less throw on the control surfaces is necessary to initiate. Servos are happier, airframe is happier, and lower throw helps exit on line better.

I am looking for something totally different than the sport fliers do. In competition, we perform these aerobatic maneuvers for a score so everything is important. In sport flying, as long as the crate remains intact, anything goes. There is no need to tune the commands for a refined response
