First off, i love these bindings and agree with TimDog about their comfort. Also like TimDog, on my 5th day of riding the cable broke in the toe strap area! I've never had a binding break on me and was bummed when i was left searching for a replacement for the rest of the day!
The store i purchased from took them back NO PROBLEM and told me that the cable snapping was a VERY COMMON issue. After looking into the issue a bit, i decided to try the formulas instead which is a bummer because i did really love the feel of the autos! Maybe K2 will sort out the issues and i can try another year....we'll see.
