How could it possibly cost you 2 hours? Don't you carry spare tubes, something to use as a boot if there is a bad sidewall cut, and CO2 or a pump? A normal flat takes maybe 5 minutes to repair, and that is not rushing.

Personally, I find that it is best for me to forget any of the "flat proof tires". A high quality high thread count regular tire (without all kinds of extra plys etc.) seldom flats if properly inflated and ridden carefully. Granted, the likelyhood of flats depends a lot on where you ride.

The real key is being able to quickly fix a flat. That means knowing how and carrying the appropriate stuff to do the job. It makes things a lot quicker if you don't bother patching tubes until you get home, just check the tire to find what caused the puncture, remove the offending object, and pop in a new tube.
