This is weird. I've ridden 0 for seven years and am a park person. Doesn't bother me a bit. When my bindings twist when I'm riding it feels so weird and uncomfortable to have them angled out.
You should duck out your bindings as well. It will feel different at first but when your legs get comfortable with it. Your riding will be easier, better and a hell of a lot safer for your knees. The 15/-15 stance is used in most martial arts as a balanced athletic stance. Again it may not be the best stance for you but a great place to start figuring out your real stance. 0/0 IS NOT A REAL STANCE!
