Hi all, I'm going to buy a WSM, but like many others, unsure of size. I originally hadn't considered the 18.5", but everyone keeps talking about how the 22.5" uses too much fuel. The problem is, they can't tell me how much more it uses, they just say it's not worth it. I'm starting to wonder if it is true. I have been using a UDS, but didn't do a good job building it, and don't have time to do another. so two questions, please help. 1. how much more coals does the 22.5" actually use? anyone have both sizes? I use lump. If you could tell me how many more pounds you need for say ribs and brisket, that would help! I also use a digiQ to control temp. 2. How does the fuel usage compare to a UDS. They seem to be similar size, and I have had no issues with fuel consumption in the UDS, I have yet to have to load extra coals, there is always leftover. is it worse than a UDS? THANKS!
