very general question. im not completely dissatisfied by my locking tremolo, but am interested in newer and better hardware for my guitar. therefore, a new bridge: is it worth my time and money?

What's the brand of the tremolo... Floyd Rose, Wilkerson...etc...

straight out of the specs:
Floyd RoseŽ Licensed JacksonŽ Low Profile JT580 LP Double Locking 2-Point Tremolo

Sounds like it's a pretty good one. What don't you like about it?

quite honestly, i only need to replace my screws since they got fairly rusty and i don't like my model's silver finish, so i got lazy and wanted to see if replacing the whole bridge will be a worthy idea. other than that, the "return action" or whatever the technical term, for the tremolo seems rather slow or somewhat sloppy. i understand it could be the springs, but i'm still fairly open to the new bridge idea.
