I have been reading a lot of posts in the forums on different builds. I am torn between the UDS and the Big Baby Double Barrel smoker. I found a local company that sells new metal 18 guage sealed lid drums fairly cheap. Almost every drum I found is 18 guage. I have a few questions I hope everyone can help me out with: 1. Am I better off building a UDS or Big Baby? 2. Will the 18 guage be sufficient or should I look for a 16 guage. I like the fact that wood is the preferred method with the Big Baby.
