Sitting on the toilet isnt all that bad, it looks funny when your board isnt up on edge but when carving hard with good body position, it is less noticeable and works well.
I have been playing with facing the nose and facing my stance, and I find if you are into EC, face the nose, but if you are into some serious icy, bumpy or fast carves, facing you stances gives you so much more power over your board, you can absorb much more and can pressure you board by pushing on it way easier than if you are facing the nose.
Facing the stance feels weird until you do it a few times and get used to it, then it makes sense.
If you are killing it on the hill, no one will see you taking a crap, they will be gawking at your military trench.
