I have tried on all of these but the murrays and boas, haven't ridden them but from trying them on I liked the Audio's the best. The reliks were very comfortable like all of the 09 ronix bindings but were too low cut for my liking (maybe look into the ones). The audios were flexible but not too low cut and I really like the footbed, its like rough instead of smooth and it feels really nice, I haven't talked to anyone who has them and doesn't like them. The boa system on the audios would work really well for a narrow foot too. Didn't like the sovens much, and the Watsons went too high up my leg but I can imagine they would be fine once broken in.
My two personal favorite bindings are the 09 Ronix cells, plenty stiff but don't go too high up the leg so plenty of room for pokage. And then the Slingshot D2s, just because they are so cushy and comfortable yet responsive.
