searchbar ftw or just go read the countless reviews on backcountry and evo. more reliable than anything here. If you're getting them because they seem 'sick' you probably should just get px12's and there is absolutely nothing wrong with that.
here people will tell you get the older 155's because the DIN range is very similar yet has the metal toe like the 18's or they will just recommend a different binding because they are a closed mind who thinks only what they use can be right.
