I'm looking into buying the masterbuilt pro duel fuel from HD but some of the comments on here are making me second guess the decision. At first I was torn between electric/propane, but I think I've decided to go for a propane smoker and this one sounds good enough to get me started. Here are my questions/concerns 1: I've never used a water pan and I've heard that these can dilute the smoke flavor, but I'm also concerned about temp control. Can anybody walk me through what you do to get your smoke started with these? 2: Wood chips vs chunks?...is it worth getting somethign special for the wood pan? I've seen people mention cast iron and I've also seen people mention filling it with lava rock and then putting wood on top. 3: Any other major concerns or things I should know before purchasing? Thanks in advance!
