Therefore I chose Conti Competition. They also have a black base tape so when they're mounted there's no white/cream color around the rim, just above the braking tracks. The tyre appears entirely black on the sidewalls and they match my black rims. Aesthetically I prefer that.
Loads of pro teams like Caisse D'Epargne, Silence Lotto, Milram and Columbia HTC race on Conti Competitions.
Does anyone have comparative figures on weight and rolling resistance? Conti competitions are 260g in 700x22.

Something I have seen to often with the Contis is that they are not perfectly round and on a stiff wheel you feel them "hop"
Challenge is the current incarnation of Clement, some of the most beautiful tires ever made but don't have the best shelf life and wear a little fast for club rides. Perhaps if you just want to best at all cost.
Veloflex is the original Vittoria Italian made tire, when Vittoria went to Asia to manufacture tires they guys they left behind founded Velofoex. The tires are fantastic but at this point it seems the modern Vittoria models have outpaced Veloflex.
The Conti Competition 22s are another good choice as an 'all-around' tire.
Vittoria Pave EVO CGs in 24mm are good 'general use' with good puncture resistance and traction in wet or gritty conditions or Vittoria Corsa EVO CX II (320 tpi) in 23mm if you are on good roads or looking for a little more performance in a mainstream tubular. The 23mm CX IIs are only 10g heavier than the 21mm and I prefer the ride slightly.

Worth mentioning that the new 320tpi version of the CXs has improved puncture resistance (PRB2.0 in Vittoria's jargon) over the old 290 tpi version so this feedback may be out of date. The 320 tpi went on sale the first half of 2009.
I like Continental Sprinter GatorSkins, I actually like the ride. They call them 22mm but they are a little wider than the Vittoria tires. I find that they soften the ride a little and are much more resistant to flats than the Vittoria tires.
Another issue with the Vittoria tires is the valves leak air, plan on them loosing 40 lbs over night. Not a big issue but noticeable.
My experience with the CX II's is exactly the opposite - 0 flats so far, on par with the Contis.
With 85 kg's and some crappy roads I will flat on pretty much everything except these two.
Sorry, but most people here already know that latex leaks and butyl stays pumped up.
Nothing to do with valves leaking.
There have been a number of tests for durability of Tubular tires. In actual tests that I have seen, the Vittoria tires perform terribly.
