I know it's not really an answer but I use the Airbone micro pump on a couple of my bikes. It's tiny and only needs to be used in an emergency but means you never are without a pump. You barely notice it next to your bottle. Think Birzman do a similar.
Prefer having physical pump than CO2 for emergencies.
