I bought non est diodes the minute they came out at a sample sale in Denver a while back.
I concur with the review:
responsive--- the highback is VERY stiff.
comfortable = great straps and buckles.
Forward lean is complete nonsense -- It take forever to get right and is pretty much impossible to change on the fly ---(Maybe this has changed as I an early sample before they went public)
I don't ever touch my lean, so it's not a problem.
All in all, a solid, aggressive freeride binding.
What B really needs to do is bring back the CO2..
