I talked to the shop rep this weekend and he's been hearing the same complaints from people who've bought them and rode them. Biggest complaint is that people struggle to enter the binding, and then have to adjust the toe cap.
I think they're getting close to an awesome binding, but the angle and size of the toe cap is a miss on this design. It's too small and the angle puts the cap too low on the boot. I just bought last year's M9.
