I have a 5 pound butt on my mini WSM right now and am so excited to see how it turns out too. I have never done a butt before either, but I'm only 25 so I guess I have time to get it right if this one doesn't turn out right!
I have to say though, go buy the pot and make yourself a mini Weber Smokey Mountain. It is cheap and may be the only smoker you ever need. I have a large Brinkmann electric smoker and I haven't used it since I built this thing. Only other equipment that ever gets fired up is my Weber Performer or my Weber gasser for grilling jobs. Great little smokers.
