The Dynafit Superlite 2.0 are the best backcountry ski bindings I have ever ridden. I am a 210 lb guy and have ridden these bindings hard for more than 130 days, mostly off piste but also several days inbounds at JHMR and Grand Targhee. They have proven their durability and reliability to me. They offer the same high downhill performance as the other Dynafit models despite being one of the lightest bindings ever made. DIN goes to 12. It is possible to get brakes for them and a mounting bracket that allows for boot length adjustment but I like them how they come out of the box.
