I would never put anything but Look (Dynastar) PX series bindings on my skis, Look (Dynastar) Pivot series on my skis, Rossignol Axial 2 series or Rossignol FKS bindings on my list.
I repeat, the only good bindings are: Look PX, Look Pivot, Rossignol FKS, and Rossignol Axial 2.
4Frnt Deadbolts are made by Vist bindings, which are really crappy.  I have never heard anything good about deadbolt bindings ever.  My bro was straightlining a groomer on a pair of demos with the real binding on them.  The binding released for no reason, he almost hit some trees, and it was all due to the malfuntion of the VIST bindings.  I would never buy the Deadbolt binding, and that is probably why next years version is made by Tyrolia instead of Vist.
