The more I snowboard, the more I figure out what I like. Such as a stiffer board, twin tip, etc. But I do think that sidewall vs. capped makes a difference. I may not be as experianced as some, but the guys I ride with are pretty good and have been riding for a long time, and they think it makes a difference too. I don't know, I guess it probably has a lot to do with the rider and how they ride. But the people I know, including myself, all feel that there is a difference.
