Unless you got a supreme deal on the internet or you got them for free, you should have bought bindings from a ski shop, or at least checked out the shops in your area to see if they mount 4frnts. I was gonna pay $150 on the internet for look px12 jibs from last year, but I went to Jimmy's Belleayre Ski Shop and bought this years badass dynastar px12 jibs for $200 and they will mount them and give me wide brakes for free.
