I just pixked up a pair of K2 Cabrawlers for a song, and I now need a pair of binding for them. Several of people have mentioned the Look PX12 or the Rossi Axial2 120's. I found these Axial2's online and can get them for $87 with a coupon code. I was also told that I should binding with flat mounts for the bumps skis, but I am not sure these are flat mounts.
