OK, I've seen that one, and he makes some good points, but does not counter the ones i made. I made a velomobile frame, seat, and full suspension from six moldings, myself, and read trade magazines on composites, so I know the potential, as well as the problems. Sheet Molding Compound is replacing more metal every year.
