Why? two C02's for the first 2 flats, pump for subsequent flats and seating the tire prior to C02. Why not just the pump? It's way too slow. All those flats might be yours or they might be your friends' flats. i won't give a friend my last C02 cart, but i'll loan the pump. If I'm on a training ride, i don't care if I'm carrying a little extra weight. If I'm racing, none of that stuff is on the bike anyway, so it doesn't matter.
If your head unit is bulky you have the wrong one.
I carry 2 C02's, a really small inflator head, and a mini pump on the frame. Why not a full size pump? I think they are ugly, and I don't think it would fit on my tiny frame anyway. I don't put that stuff in my pockets because my pockets need to be available for other stuff.

i carry a frame mount pump (first coice) on my main bike. My winter bike I stuff a co2 cartridge and a inflator thingie into my bag, because I don't want to deal with moving the pump over and buying two pumps seems silly. But I much prefer the pump. The cartridges/head unit are heavy, bulky, and are a one-shot deal with no control over final psi. Plus, it's very possible to botch a tire repair such that the first inflation attempt fails. Pumps rule.
