Im buying some 4frnt stl's, and I was wondering about sizing and bindings. For sizing im 5'9 and 130lbs, and im not sure whether to go with 167s, or 177s. Im center mounting but im not sure what kind of a binding would be best, my last ski had some Look px 18 fs and they worked out pretty well but im not sure about any of the other brands. Anyway help would be great
