I actually haven't.. I even considered buying one at one point but I honestly love the hybrid camber from NS so much that I can't find a good reason to buy a different brand. I'm debating between a Proto and an SL.. I just want something with a little more pop and stiffness. I demoed a Salomon Sabotage that I really liked though.. Have you ridden any of their boards ?
