it's mostly foot control and momentum...brakes? because the ground is never ever perfectly flat and if you start off with the spin going towards a downwards slope you might have pick up too much speed/ momentum to hold the position without going spastic and need to scrub it off, thus the brakes.just learn how to feather the brakes; imho clear brake pads are too "sticky" for a rider to use smoothly, especially on rolling and turbining tricks.
