Hey Guys I skied the new Z12 for all of last Spring and I had absolutely no problem with it pipe, park, or freeride. It is lighter than anything else on the market. A toe and heel weighs less than a heel piece from Look/Rossi and it has more retention as well. I know it is hard to believe, but once you step into the binding and actually ski it, you will see that it is actually pretty bomber. It is also lower to the ski than previous models which also saves weight and gets you closer to the ski for better control on rails. I have a feeling next year there will be a Z14 binding for those of you who want a higher DIN, but for now I think the new Z series of bindings is going to be a huge hit.
