IIRC you can get a Corvette, Streamer, Fortress and Vampyre as a Rockbass. BTW the next generation of RB's will have the 2 piece bridge and W on the headstock and look a whole lot closer to German Warwicks. 2 things that can do, get you a lot closer to your CS idea, or if you don't care it might drive down the prices of the existing RB's with the 1 piece bridge and huge RB logo on the head.
I thing I do wish, though, is to be able to get RB's with different coloured hardware, I'd love a Vamp with black hardware, the SN Vamp looked killer.
