I live in CO, and ride out here in the western states almost exclusively. I am on a Turbo Pro RMK, and am going to give the Peak, a shot this year. I have heard the same thing that Paulharris said, about guys trying it and taking it off after a couple rides. What I have been told by one of Camoplast's R&D guys, is that the Peak was designed to be similar to the Yamaha Ascent track. The Idea being that the middle lugs, and tips are softer, while the base and outside are stiffer. The thought being that you would "channel snow, and pack it down under the middle of your track". I was also told that this track takes considerably longer to break in, than say a challenger (hence people trying it and switching it out after only a couple rides), but once it does, it will perform better than any other track, for high HP/high torque sleds (4stroke Yam/Turbo 2 Stroke), in deep dry powder conditions.
Again, this is all stuff I was told and had explained to me by a Guy that works for Camo, I cannot attest to any of it yet for myself. THe way it was explained, it makes sense to me, so I am going to give it a shot, and let it break in for a good while this year, before I form any solid opinions. Hopefully it will be as good as touted.
