how long will it last?

[artbrewer]

just a quick question about kegging.
i will be using a 2 tower system for homebrew
i wondered how long a 5 lb co2 bottle will last on this system?
should i just go for the 10 lb bottle?

thanks

I'm on about keg number 9 with a 5# bottle and still have gas. Unless you go through a ton of beer, a 5# tank will last quite awhile.
