Rome Targas and Flux SF45's were the 2 freeride oriented bindings I looked at the most and settled on the Targa.
I believe from Nitro look at the Blackhawk. I remember seeing a few posts of people very happy with Salomon Chiefs.
From Burton I would've said C60's but they got rid of those... not sure what they replaced it with this year. I see the Genesis is new so that might've been it's replacement.
