The biggest kicker at my local park is 35 feet, and I'm trying to progress on it as much as possible. What do you guys think is the largest amount of rotation that someone could do on this jump? The biggest I've seen so far is a 900
I agree with ThunkChunky that there is no obvious limit to tricks someone could do. I've seen a guy do a 720 off like a 10 ft jump in real life.
In the video below the rider is throwing flatland 720s and throws a 900 off what looks like just a natural roller (around 0:50)
So stop worry about the jump... a 35 jump can allow for more rotations that you can ever do. So keep practicing!
