I've found...and remeber reading somewhere, that wider stances are better for spinning. And it makes sense to me...since you can generate torque due to mechanical advantage, much like gripping a tire iron at the ends. Of course too wide gives you less leg motion and is harder to balance this way.
I've found for myself, the alieviation of the wide stance pressuring knees problem can be solved simply by increasing the stance angle. I used to ride 0 0 for all mountain. When I switched to mostly spinning and freestyle, I went widest and 15 -15. This way, when I bend my legs and it's in more of an "angle" because of the wide stance, my feet are more aligned with my thighs...reducing that "axial twist pressure" on my knees.
I imagine every body is different and wide to some is short for others and some ppl are more flexible and in certain postions, etc. too. But you can try what I did and see if it solves your knee problem.
