Yep you want to duck your stance so that if you land switch your front foot is still pointing down the hill. Not a lot is needed. Each person has to experiment to find their own stance that works for them. Each person has different feeling, and everything.
If you're sticking with just one direction, try angling your front binding higher than your back. I have mine set up to 27 front and -12 back. This helps me see forward easier with my eyes and the shallow rear angle helps me adjust/turn my ride with my rear foot/leg. If you're planning to ride switch, go with any of the guys who posted above.
