the colnago looks hot with that front tire. you need to mount a match.
i really like the RB-1 too. i still vote DA 10spd downtubes and derailleurs teamed with those cranks and period correct DA brakes and levers. the tri-color/105 stuff looks nice but the DA mix would be unique and it would allow you to swap wheels.
the pedals look great on both. i think you will be very happy with them. they are heavier than keo pedals but i dont think my keos are going to last as long.
