Replying to Buying new Bindings!

So I just got a brand new pair of Faction Ambit (women's slopestyle twin) and need to get some bindings for them.

They're 86 underfoot. And I'm trying to keep them under $200.

I plan on using them for park (rails and small jumps), but I'm about to move out west so may spend a bit less time in the park and more free riding.

To keep in mind, I'm 5'6 around 160lb so I don't need a massive binding. The skis I have now I usually hover around a 6 or 7 din setting.

Also to be noted, I have some pretty bad knees (multiple sprains on both) so something with a smooth release would be great.

Any suggestions would be much appreciated!
