Yes, it get's easier with practice. I was on a club ride yesterday, flatted, sent everyone else on and caught up in under 5 minutes. Inflating with co2 sure speeds things along.

Now if only I had left that sliver of glass in my tire instead of brushing it out. But you only find out if it's in the tube the hard way

I think I need to throw an Armadillo on the front, it has worked wonders out back.
