+1 on the Road Morph, although I no longer can use it. My bike now is too small and too rounded to hold a pump. I carry the cartridges and an adapter that my DH has adapted even more. I carry 2-3 cartridges, since we ordered a box of 50 from a supply store that is not a cycling place. They cost about fifty cents.
I didn't have any flats this year. Well, I did have one on my Jamis, where I do have the Road Morph. Too bad I can't get that little wire back into the V brakes when you take the wheel off/on. It effectively stops me from changing a flat on that bike. So I bought some heavy duty tires and I pray when I ride it.
