I can't speak for tubulars as I have never rode on any, but I have gotten wuite a few "violent" flats using clinchers. That is insanely scary at high speeds and I'm assuming the tubulars slowly flat out as opposed to a shotgun like blast?

I can see the appeal of tubulars, but can also understand the hesitation of trying them for the first time. Expensive right off the bat, but would prob cost pretty close to what you spend on tires/tubes in a given time.

As for price... From what I've read it's not really that much more expensive when you compare to tires + tubes.
