Yeah I still keep my frame pump with me.. cause for one thing, say you get a blowout, and can't find the hole... you wanna waste co2 so you can find it? Also, I like to check my patch job with it... then I put it back in the tire, hit it with the Co2 and away I go.
I use 16g cartridges... the 12g ones don't get enough air in there for me to feel comfortable about not getting a pinch flat.
I've also heard that going 10% over isn't bad...and some people actually recommend it...
I gotta find cheaper cartridges though...the LBS wants $3 each, and I'm morally against shopping at walmart...
