it's all about feel in terms of the speed you need to get to the top of the wallride and not go over or come short (I flew over the top of the wallride yesterday, yay for learning the hard way). come into the wallride with legs shoulder width apart, centered athletic stance, don't lean too far forwards or else you will face slide or ass slide the wall. when going up the wall, no matter what do not lean to far forwards even though you feel instinct to, when you get to the top stall the ledge and give a little pop and drop back switch, when you drop back switch don't look over your shoulder. Going down keep your skis shoulder width apart and your centered athletic stance. Progress your way to 1s at the top and shit.
