Got a new combo gas grill/gas searer/charcoal grill/smoker from Sam's on Father's Day. Really excited to get into smoking some meat! From Hot Springs, Arkansas. Here's the rig: http://www.samsclub.com/sams/smoke-hollow-4-in-1-combo-grill/prod3920115.ip?navAction= Any tips are appreciated. My biggest question right now is should I use lump and place the wood on top to smoke or just burn the wood directly. I purchased some of the Western brand pre-cut hickory chunks and the instructions on the bag say to burn them directly, but it seems to me like that would burn up a lot of wood and at 12 bucks a bag that'd get expensive quick when you're cooking for 12 hours at a time sometimes. Thanks!
