Hey, I have been having troube with my bindings, I came out landing switch in the pipe yesterday, i landed and leaned forward and my skis just wiggled out from underneath me, i tumbled over my fallen off skis and messed up my knee. I have them set on seven on the toe and six on the heel. I weigh 147 pounds. What do you guys that are near my weight put them on? What do you suggest I put them on so this doesnt happen?
