where do you ride?
When bombing, going right down the fall line...there are no edges to catch. This is because the toe and heel edge are parallel with the fall line. So you just got to keep a bit of weight on your nose, keep your upper body quiet with shoulders and hips closed/parallel with the board; and your legs, knees and ankles loose, relaxed. As for being low...try alternating between standing tall and crouching as low as you can get...like taking a shit in the woods.
