Did you end up choosing a binding? If so, what did you get and have you tried it out? I have the exact same dilemma. Currently, I plan to go with the '13 Cartel Re:Flex. They've improved the high back and made it more responsive over the '12. I've been reading about the Rome 390, Union Force and Union Contact. I'm really looking for dampening and cushioning. I read that the Burtons are excellent on that. The Good Ride has reviews of all of these bindings. I compared all of the How It Rides tables on them. I currently have '08 Mission that I like, but I want to take things to the next level. I think the Cartel will do that for all mountain without being too soft.
