Anyone and everyone that is not riding the same stance as Shawn White or Trice is wrong..
.....Just kidding! ride what feels good for you.
Takes some messing around to find what works for you, your body, riding style blah blah.
Both my boards have similar angles but my freeride board has +3 degree on both the front and back binding compared to my freestyle board. my stance is maybe .5-.75 of an inch wider on my freestyle board as well.
