My main focus will be jumps, the rails/boxes come as second.
I heard the Ride Deltas fit these traits pretty well but they're sooo much more expensive than the two Rome's I listed (like 60$ more than the 390's WTH?!).
How do the Delta's weigh into the equation?
Both Ride and Rome build good bindings. The Delta's, IMO, are similar to the Targas in terms of flex. Ride has had issues with their ratchets and Rome has had issues with their base plates/discs. If I had the choice, I'd pick the Rome's just given that they are $60 cheaper and they have an impecable reputation for customer service.
