Nice binding and certainly gives the Low Tech Race soem competition. 1/2oz heavier here and the 4 screw rear mount isn't as impressive as I first might have thought.

RSR has four holes in the heel piece

    The model in the picture is an older version. New version has four holes in the heelpiece. Be fast!

    Besides -3oz and +$200, what do I trade off when going with these vs. the Dynafit TLT Speed Superlite Binding?

    Unanswered Question

I used the RT binding in the past on a ski that was 138mm under foot so I was thinking maybe this binding could do the same on a ski 130mm under foot.
