I haven't skied it, and I haven't been contacted about my pre-season order either... not sure what is going on with the company.
Phil's explanation is good, but extremely simplified (he's right to simplify it, it get's REALLY techie). There is a LOT of science and research that this binding addresses that more traditional bindings have turned a blind eye to. ACL injuries are often associated with what is known as the 'Phantom Foot' type of fall (http://www.ski-injury.com/prevention/kb
), these falls have been more or less considered part of the sport and an inherent risk associated with it. Knee Binding is an attempt to change that. The Tyrolia Diagonal heel requires the binding to lift upward at the heel before it rotates outward and LOOk P series and FKS type bindings don't allow the binding to release to the side at the heel AT ALL (a very common misconception). They may provide slightly less torque to the tib/fib but you aren't getting out laterally unless the binding rips off the ski.
The danger with any 'New Idea' is that there are standards already in place which will get distrupted by this. The Knee Binding has an additional release direction which requires an additional DIN Chart column... that might not go over very well with the status quo. The Knee binding also only releases to one side at the heel (outward) this prevents the binding from pre-releasing while the ski is on edge but means you will have a dedicated LEFT/ RIGHT ski, some will consider this a great trade-off for additional safety... others will object. S for it not being very different, I think that it is VERY different. I also think current bindings are excellent as safety devices, I feel skiing at a high level produces injuries, don't wanna get hurt? Stay home.
As for LOOK fans... much of the technology in this binding shares DNA with LOOK, in fact the heel cup is very similar to a LOOk toe... but if you ski on P18 this isn't the binding for you.
It's a very good idea, it's very well backed up with years of research, it solves a problem that everyone has known about for quite some time (since the first DIN standard)... but it's pricey, it's complicated and it's a new company with no track record. Will it make it onto consumers feet? I don't have a good feeling. There were rumors of hostile buy-outs by the financier of the project... who knows.
My gut feeling is in order for this to work someone bigger will need to buy the design build it and market it. I don't see an independent binding company surviving in the current ski industry. One of the biggest problems is the target market is (or should be) recreational skiers who want to have fun without getting hurt, this binding is PERFECT for them but no recreational skier is dropping $500 for a binding. It just won't happen. Experts and pro skiers who are out everyday might give it a shot but they also are going to get less benafit from it.
