I didnt have any trouble moving my 3s from 20 fters to 40 fters and then bigger. Just remember that you dont have to wind up at all really, just pop and look over your shoulder. Commit, and dont stop looking over your shoulder. Spot your landing and put on the airbrakes(just try to open your body up as much as possible, it slows your rotation a bit) if you need to. Good luck man, they're really fun to float.
