if your not doing anything cork, your just spinning, i like to pop off of my oposite inside edge. so if you spin left, pop off of the inside edge of your right ski, and if you spin right, pop of the inside edge of your left ski. make sure your not doing a wedge into the jump, keep them parallel. if you do something sw cork or whatever you might carve, but just for spins pop off the opposite inside edge. that really helps me, but other people might be different
