dude, why don't you just buy some decent tubular tires and watch where you ride?
all you have to do is carry a spare tire and if you ride with a bag then it's no big deal.
just put two coats of glue on your spare tire and let it dry before you wrap it up, carry it with you then when you flat, you just swap the spare on and pump it up and ride.
i rode around for 2 weeks on a spare like that. it's perfectly fine. just don't corner like you're leading the pack in a crit.
