two super important things which helped me learn them pretty quick are:
if you are in the chicken loop, then hold the bar close to the middle instead of at wither end. this way you can hold the power in better. Otherwise stay in the main loop.
Another good tip if you are using the chicken loop for your jumps is to jump when super powered. In fact, i find it very difficult to do any one foot jumps unless i am powered enough to go big. Don't bother when you are trying to force jumps. Eli
