I would say Im a beginner/intermediate snowboarder. Iv'e been snowboarding a few seasons but i just bought my first board. My question is, How wide should my stance be. Im, about 5' 10", and I read somewhere that it should be between the width of you shoulders and the length of your shin. So that means I should set it up between 23 and 21.5 inches. The guy who set it up at my shop set it to about 24 or 25 inches i think. I want to get more into park riding so I was thinking that this wider stance might be ok for me. What do you think? Also, I was wondering if a wide stance was bad for you knees. I have a torn ACL which Ive had for a few years now so i ride with a knee brace, but my knees are kinda bad.
