I love tubulars and have been racing road bikes on them for 15 years.

I should say that I find Tufos to be rather too fragile. They are fine racing tires but after 6-10 races you'd better change them. The tread is very thin and they flat much too easily. That is the last brand I'd recommend for brakeless fixed gear riding. But perhaps one of their heavier tires like the T28 would be suitable. But forget about the Road Elite or S models. Anyhow, after flatting out of a road race on a Tufo Elite Road week before last, on mile 2, I've given up on mine and I'm very glad that my team was sponsored by Schwalbe this year. We did a tyre buy and I bought 10 tubulars for 20 bucks apiece on 2004 clearance!

Also, I must say I think that this is a bad idea if you live in a city where you'll end up skidding a lot. Rolling the tire shouldn't be a problem, BUT if you watch crash footage like Beloki's his tire rolled after he got real sideways, so use some caution. I just think you'd be going through many tires and it would be costly and time consuming.
