The ultimate combination of weight, performance, features and price for a serious touring binding!
Assuming you aren't dropping cliffs or using this binding inbounds, I find that it offers plenty of performance for fairly aggressive skiing on a relatively large ski (184cm 99mm underfoot dynafit denali). The weight is incredibly low (1/3 of a radical FT) for the amount of performance it provides. I have not yet had a pre-release nor have I crashed and tested its release capabilities (but it is comforting to know it CAN release unlike the low tech race).
I was worried about the lack of a flat tour mode but having high-articulation boots (TLT5 for me) makes it barely noticeable. In fact I find the lower of the 2 touring positions to be wonderful on low-angle skin tracks where the middle setting on a conventional dynafit binding would be a little high. The higher touring position works great on all but the steepest of skin tracks. Not having to ever rotate the heel during any transitions is very nice (just flip the heel lifter up/down and go!)
The extra heel lifter, releasability and $250 savings (and likely greater durability) for a mere 75gram weight penalty over the Low Tech Race makes it a great buy for all but the serious racer.
Only minor downside I have found thus far is the toe lever is harder to lock using your ski poles while standing up (being lazy and not wanting to bend down) than my old Vertical FT toe levers.
Contrary to Patrick's comment about leashes, I was easily able to attach a small, homemade leash to the toe pieces.
I have less than 10 days on these bindings so far so I cannot yet comment on their long-term durability but have not experienced any issues thus far.
Overall this is a great binding that I highly recommend and plan to buy again for my next pair of skis!
