as for your stance I would go low, wide and slightly staggered. its a mix of both. With a mix of whatever feels natural.
Oh, man I would never TRY to get my ski tip to drag off the jump it just happens some times and you have to be ready for it. Try and let your hole body take off as one after your pop. Like in a back flip tuck, imagin letting one foot drag behind.
you digg?
