one day at a mates house we were in a bit of a crazy mood (not on unicycles tho unfortunately) 3 of us and we had a video camera (of course) lol. we got square trampoline of his and leant it up against an old tank stand and ran at it, jumped and were doing backflips and 180 flips and stuff. it was sitting on about say 60 degree angle to the ground. made doing flips and stuff to ground wayy easier and i recon if you set up mat or something at an angle and could rolling hop high and far enough something mite be possible. im only learning to rolling hop atm so iv got no hope.lol. im more of an fmx rider than unicycles and i cant backflip a dirtbike yet either,(new 8foot high ramp comming before the end of this year tho hehe.)
just chucking an idea out there.
good luck to anyone who even tries it i recon its mad as. latr.. paddo
