ski bindings for armada arv

I got a armada arv 175 cm. my weight is 165 lb and height 5'10.

I need to get binding soon so i can use my new ski :) . I want to get binding that will be good for allmountain stuff -- esp. powder. I am intermediate level (easy blacks and blues) but do not generally go to the park.

Also i have a boot from my last ski set up -. Will i be able to use the old boot now and use a new boot later?

I was looking at the Fischer x13 97 or Rossignol freeski2 120 xl ti but any one ideas appreciated..

Thanks

Welcome to J2ski :D I believe I use similar to the Rossi binding you've listed, which is also known as the Dynastar/Look PX12, and think they are really effective. They have a bit of an advantage in powder, if you lose a ski and it's hard to get into a position to step back in, you can pull up the heel piece to get the ski back on.
