rome 390's are like brittle cinder blocks compaired to union... go with either union contacts or forces. union bindings are all bombproof and the lightest out there.
There are a bunch of great soft bindings out there.
Personally I ride Rome 390s, I love them so much I have three pairs.
Also check out FLUX bindings, and as alex said, unions are not a bad choice.
