Just a thought.

Writing boldly that you rarely get flats may be just what you need to trigger a large number of 'em. It's the way things go.

As for pumps, I just switched to the Lezyne from the Road Morph because it is so much smaller and neater, and it fits inside my seat-post bag rather than strapped to the outside of it. But I am thinking about switching back. I don't find it pumps up as well, and it's a little more fiddly to use than the Road Morph. Never used CO2, and never felt the need to do so. It's one more thing that can go wrong.
