So this year I've been having big problems with my Z12's. The friction plate kept sliding out and jamming when I landed tricks and even during regular turns. It finally popped off last week rendering my skis pretty much unusable. My heel plate cracked, by brake bent, etc...anyways, so I brought my skis in to my local shop for the 5th time this season and when I went to pick them up I had brand new 2009 STH-12's mounted on my skis!!! My shop guy said that they explained Salomon the situation and agreed to upgrade me. Sooooo sick, props to Salomon.
