riding pow 8"+ then longer, otherwise whatever. Might gain more control if you widen your stance.
Yeah, I have tried widening my stance before but I just can't get used to it. So much easier for me to hold an edge with a narrower stance. What does make me more stable is when I offset my bindings, but I am not sure if that is recommended.
For example at the end of last season I had my front bindings in the center holes but my back bindings one set of holes up. So my stance was the same length but I was more forward on the board.
