I played a 5 string Streamer $$ yesterday (unplugged) and now want one - based purely on it having the ideal ergonomics for me. I'm a bit put off by the complexity of the electronics (just want one passive pickup, me). Anyway, given that any Warwick 5 string will have the same awesome neck, I'm checking shops for their alternatives, and it seems that practically all pickup and build options are common across the range. So is the only difference between a Streamer, Thumb, Corvette, Katana and Infinity etc just the body shape? Obviously the Thumb is tiny so is presumably lightest, but is a Streamer always heavier or lighter than a Corvette, for example? And which IS the heaviest?
