The Salomon Smartrack will take the normal Salomon Wide Brake no problem. The new smartrack was very impressive to ski. It really changed the way that certain skis skied. All for the better. Nice flex on skis up to about 100mm's. I skied one with a 103mm in the waist and it was still a lot of fun on a ski that wide and a plate. One of the best bindings out for 2007 is the Z12 Smratrack. The binding itself (not with the plate) weighs under 4lbs for a pair.
