My wife doesn't like a heavy smoke flavor so I don't want to over smoke my first Butt tonight.... The woods I have to choose from are Apple, Hickory, Pecan, and Mesquite all in chunk form. I was going to follow what this guy did in this video for Minion Method, would the amount of wood he puts in result in a light or heavy smoke? I will be using my WSM 18.5" and I'll be starting the smoke at 11pm tonight for dinner at 6PM Saturday. The Butt is 9.5Lbs.
