There's not a lot to it. Land with your tips (or tails) up and crank your dins. You're gonna lose skis occasionally, and it might take a while to find them sometimes. In my experience, most of the times when you lose skis in powder it's not from hucking huge cliffs or tip diving upon landing, it's from pre-releasing during a turn or clipping rocks under the surface or other stupid little things that you can't predict.
