If you want to go with lighter tubulars check out Veloflex Servizio Corse and the like and accept the fact that you may well puncture more often and that they're only 20mm wide which means that you'll have to be careful in tight bends.
I beg to differ. 20mm tubulars are no more puncture prone than bigger tires, particularly when kept at the right pressure. Any unlucky foreign object penetrating your tire will do the trick, regardless of tire size! You will typically run smaller tires at a higher pressure and they have a higher rolling resistance than wider tires, but there's an offset in aerodynamic footprint which somewhat balances the increase in rolling resistance.
Then there's the cornering. Being round instead of c-shaped with bead hooks, tubulars are inherently more flexible, henceforth enabling cornering at higher speeds without losing grip. There's nothing that says you can't corner faster with a 23mm, in fact, a 3mm decrease in ride height, therefore a lower center of gravity, makes for even more stable cornering. The only concern with 20mm tires that I think fdegrove warns for, is that your pedals tend to hit the ground sooner when pedaling while leaning into a corner.
Another benefit of a tubular tire is that you can ride home on them despite a puncture, be it carefully so you don't damage the rim.
One of my personal favorites are 20mm Schwalbe Stelvio Tubulars, which weighed about 180, looked good in all black with white logo's, and have no innertube since it's one piece vulcanized with the tire. Just take some Vittoria Pit Stop and a pump/Co2 canister and you should be fine for the majority of punctures.
