Replying to ARV JJ116 UL / Whitewalker

I am currently thinking about selling my old Rossigniol Soul 7 with an alpine binding, and then buying myself a nice downhill oriented pow/touring setup. As a binding i am considering the Atomic/Armada/Aalomon Shift, or the Marker Kingpin.

Now to the interesting stuff: Does anyone have any experiences with either the Armada ARV JJ116 UL or the Whitwalker? Just cant decide which one is better :(

fyi. i am only skiing in the alps (Austria)

Happy to hear your guys opinion.
