Yeah, I ended up not being able to get myself to jump all that high, but I was off the ground. It did work actually. However, my sparring partner is awful at shooting... Mike123 beats me in Judo, but he like...tries to football tackle me and calls it a shot -- all bent over at the waist and stuff. But, yeah, the move you suggested sent him crashing to the floor.
I'll test it more extensively against someone who's better at shooting, when I get the chance.
