The main difference is that the board need not flex so much. Thats why I can draw great big perfect C shapes even when I lay it down, on a more regular board I would be biting in hard at the start of the turn simply due to the mechanics of tilting a long edge, short radius board. The short edge, long radius board will produce the large turn shape we want without so much crazy stuff going on all over the place. Simplification...The shorter board with large sidecut thing sounds interesting, as long as the snow is right. Alot of the heelside turns look ugly when going so low and tight on regular boards, they just chatter up and skid out.
