Ok I'm in the market for an aftermarket shell right now. I work for a truck company and we are designing a shell (the graphics) for my slash. I was going to go with a Proline shell but have read they are heavy and not as good for racing. I don't race yet but am getting into it. Is a Proline shell really going to be that big a disadvantage when on the track? Should I just get a stock body and paint it?
