I'm about to get into Kegging and I am working with a budget. I am considering just having one faucet at first and switching the beer line between two kegs (gonna by dual regulator)? Anyone else do this and have any advice? I was listening to Brewstrong archives the other day and Jamil was saying he basically only uses one faucet at a time - hooks up a keg, poors a beer then disconnects it, sprays the faucet with starsan and continues the process until he feels its time to clean the tap. I don't really drink during the week and only a few on the weekends. Any negatives to this approach besides having a mix or tossing a few ounces each time? Also, how long does the beer that is in the line take to go flat?
