ive got the old viper 254, its a decent take on an SG shape IMO, and "agressive" would suite it best.
probably the heaviest bass ive owned in every sense, the volume pot is dodgy on it but any bass can have a fault i guess.
its currently sat on a my rack and its not been played since i aqquired my fender couple of months ago, but what i wanted in a bass changed.
anecdote aside, if its what you want then go fo' it. a couple of guitarists i know both have LTD's also and both are borderline too affectionate of them...
also the LTD surveyors look bargainous on GAK. last years models i guess
