I just got some 172cm chronic blends and i'm looking for some suggestions on bindings and where to mount them. Im 6 feet, 145 pounds, and a pretty aggressive skier. i do about 40% all mountain, 30% park, and 30% powder. I was thinking about mounting them about 2 cm back from center but im not sure if that would be the best. As for bindings, im looking for something good quality. I was thinking about salomon Z12 ti's. Are these a good deal for their price?
