I have a pair that i was on for about the last 20 days of skiing last season. I have mine mounted with the 4frnt deadbolt 18s and it weighs just slightly more than the dukes do. I do like them a lot better than the dukes for a few reasons, 1) you are a lot lower to the ski for more control, better ski feel etc. 2) the mfd flexes with your ski so you arent completely jacking up your natural ski flex 3)I dont trust marker bindings. after blowing up 2 pairs of jesters in a season a couple years back i am not really too stoked to be on those. 4)more natural skinning motion(for me anyways) 5)I dont have to take my boot out of my ski to change it to tour mode.
I am picking a dynafit setup very soon so if anyone is interested in the mfds pm me. I would sell them for less than the new price.
