One day last summer I had 3 flats on the 27km ride to work. I have Armadillos too. The flats were on the inside of the tubes. The rim strip wasnt covering the holes over the spokes 100%, so the 105psi was enough to make the edge of the holes cut the tube. When I got home I put a file to the holes to round the edges, and was careful how the new rim strip lay. I havent had a flat since.
