I have done a lot of experimentation with different stances.
If you go wider than the reference stance, the board will most likely be less responsive to foot steering. However, for dynamic carves/skidded turns, there is no difference for me.
I had issues when carving, with the tail being prone to washing out with a wide stance. That was caused by rotating into the turn, resulting in the tail being at a lower tilt angle than the nose. With a narrower stance, I could largely compensate for that by keeping the back knee back. Not rotating into the turn fixes things for me (and the wide stance works perfectly fine).
