Fins...... Ever wonder why when you change your fins it makes you board work completely different?? It's not just about the size or the shape of the fin but the placement, cant, and pitch of the fin. Front fins facing to straight and the board may go super fast but may not turn. Front fins facing to far in towards the stringer and the board may turn way to sharp. Fins that stand straight up May be super fast but may lock on the face and not release. Fins that are to canted may not have enough hold and may wash out on turns. You can't change your fin placement and angles therefor your leaving that totally up to your shaper, but you can change your board by changing up your fins.
