No experience with Gatorskins. Using Armadillos on the winter commuter MTB, 1 flat in 2 years.

I've heard tire liners are very effective too, these are the thick rubbery strips you lay between tube and tire. You are supposed to trim the strip's corners to round from square, else the square corners will cause flats.

Running Panaracer Paselas on the summer commuter, they are supposed to be flat resistant but I get a flat every couple of months. On a weekend ride I don't mind a flat but going into work in the dark and rain, I do.

Last week I flatted on the way in. Changed the tube under the light of a bus stop. Flatted again a mile later, in a homeless-infested area of downtown, and no more tube. I walked the bike the rest of the way. Now I carry 2 tubes.

I'm gluing up some tubulars to my speedy bike. I will be really irked when they flat. Tubulars are not cheap! And carrying a spare tub kind of cancels out the weight savings.

I've ordered some flint catchers. These are wire things that lightly brush your tire, hopefully removing that bit of glass before it penetrates. We'll see how they work.
