I had some old missions that I kept stripping the ladders on them, every year. I wear my bindings ridiculously tight. When I looked at the ratchet I could see a noticeable slant so that the ratchet didnt engage the ladder perfectly straight. When I shopped for bindings this year I noticed that the '13 missions still have that angle on the ratchet but the cartels sit very flat on the ladder. This lead me to believe that I would have less of a chance at stripping the cartels, so that's what I went with. Hopefully that theory was correct.
Just something to look at if anyone else has that problem.
