I like the Holdsworth/ IRD 48-34 compact cranks. They have a vintage Campy / Sugino look with drilled rings. Have on 2 vintage road bikes. Velo Orange are similar... made by IRD as well, I think.
I have Shimano 46-36-28 triple on my Shogun tourer and a Campy Daytona w/ triplizer on my Trek 660. Everything is 5 or 6 speed rear w/ friction shifters and vintage derailleurs.
