Tubulars are by far the lightest. Got a pair of mavic gel280 rims in 28h hanging up. 305 g each.
The problem with all very light and narrow clincher box section is they are hopeless unstiff. You end up having up the spoke count and use thicker spokes to get it to hold together and to give it resonable stiffness.
Those mavic i have will be laced to fixed gear hubs that should work fine. So if you do buy those am classic rims i hope they are going to be used with fixed gear hub that could work.
