ok, heres how to learn pipe:  pick a spot where you're comfortable dropping in so that you can go straight intot he wall without speed checking.  even try just dropping in straight and seeing how big you can go with not much speed. next, once you're comfortable with that, ski along the deck for a little bit before dropping in to get a bit more speed.  once you're comfortable with that try dropping from a little higher, then a little higher, and keep dropping from higher with more speed until you're going huge.
