FKS turntable and the pivots.
keep in mind that I have jesters(on the bentlys), and I like them, I just would prefer to put FKS binders on them.
I do like the jesters more than the px whatever series that rossi/look has, but IMHO FKS dominates. you get such a good flex on the ski, and they hold you in. Jesters also lift ya up off the ski, which I don't like, but it can give a little easier edge to edge 'control'.
Though I agree, sally binders blow.
