Pros: ease of use, inexpensive, support aggressive lines
Cons: pre-release in some conditions in climbing mode
I've been on these bindings for about a year now and have skied them in the Idaho backcountry, as well as multiple trips to the Tetons. I am agressive and ski some steep lines. The initial foray was on the Middle Teton glacier from the top of the couloir at the Dike col. The snow was very firm and pitches in the upper 40's to low 50's. No problems.
I don't do a lot of "hucking" anymore, so I can't say how they hold up for you cliff jumpers.
The only problem that I have had is that in free heel mode, even with the binding locked, i have had the toe come out if my knee was very close to the ski. This can occur in steep uphill climbs.
I have never had them release when skiing downhill
I ski them with a pair of Dynafit boots and they are fully compatible. My main purchase decsion was the price and I figured that if they didn't work out, I'd pay more for the Dynafits.
