Astrix Rook: Anyone ride one yet?

Looking at the Astrix Rook and curious if anyone has ridden one yet. I am looking at it partially to save some weight over my On-One Inbred 29er, partially to try something different, and partially because it's one of the few aluminum models to still offer vbrake mounts.

I'm 6'2", 225lbs, and ride in Colorado Springs area.
