Yeah, I'm going to have some questions. This will be the first thing that I put in a keg, and I'm doing it exclusively to ensure the proper level of carbonation in the bottle. Like mmb said, too much time involved to risk it not carbing. I've got quite a bit of biermuncher thread reading ahead of me, and it scares the crap out of me!
Don't worry, it'll be fine. How many gallons did you end up with?
