Okay, a little history about myself first. I work for a high end appliance dealer and I've used just about every grill/smoker out there. We always test and put the product through the ringer before we take the line on. So anytime in the last few years that I felt like doing some serious slow and low, I would just choose between a Green Egg, Primo, Texas Barbecue, Traegaer, ect...ect. Well, I finally got sick of not having a "upright" smoker at the house. Out of all the choices that I had to choose from, I picked the 22 WSM. I chose it for it's capacity (61lbs so far) Ease of transport, break down, and cleaning. I don't care what anyone say's, A Green Egg is not going to make your Que any better then a WSM. The factor there is the cook, I've used both several times and I get the same results. Were is does differ obviously, is the duration of cooking time. I'm not asking or expecting the WSM to run as long as a Komodo Kamado. But I would like to get a solid 10-11hrs without a drop in temps and without refueling. The best I've got is 8 1/2 at 245 using 10lbs of royal oak spilling over the ring(minoin style) and using ceramic drip tray foiled. So what's the secret? Do I just need to use more fuel? I've heard of people fitting 15lbs of kingsford briquets and getting 12hrs, but I will never use those things. So any tips will be appreciated
