Whatever you want to do, do it! I set mine up with more cant on the back foot, forcing me (in my mind at least) to keep the proper stance = more weight on the front foot. I'm gonna play with it next time I go riding. It finally started snowing here but stupid work gets in the way many times.
I have it setup like this: I ride regular with 20 and -10 or something like that.
Left binding: 0° in the rear part, and 2.0° in the front. Rear is full 3.5° front and back.
