Thanks for the solidarity, fellas. I even bought a nice set of tire levers, too... It mostly annoys me to spend the money on what should be a simple job but, in the end, I suppose it's worth the peace of mind. Flatting in the middle of a hard turn was, well, not fun. No interest in repeating that experiment.
What makes me most annoyed is that it held air overnight after my install without any fluctuation. Held air for a 20 mile ride, then when I went back out at the end of the day after it had been parked, it was completely flat. GRrrrrrrrrr!
