Rob,
I'm leaning towards flat black, no badges and some sort of artwork on the sides. I'm going for a rockabilly, hotrod look. Devil's head, aces & eights, pin-up girls... that sort of thing. Otherwise, flat black with gloss black pinstripping.
I originally wanted flat black with silverleaf scallops, but Rikki Rockett bet me to it. And I'm no "me-too" kind of guy.
Mike
