It's time to bump this back into the rotation!

I want to attach 3 pin bindings to my Madshus Eon skis for more downhill control. What is the difference between the $85 one and the $300 one? Voile: Telemark Bindings

It seems like a durability thing that will only matter if you're doing some really aggressive skiing. The cheaper one will be far more flimsy, like MTB pedals/shoes to some carbon soled SPD-SL?
