@Jason Williams Just wondering what you decided to do, which size you bought or did you go another way?
I have worked my way through offsets with wood, charcoal or propane as fuel, horizontals with a rotisserie, then ugly drums, then a tricked out 18 WSM, followed by a tricked out 22 WSM, kettles and such with the number of people being fed in constant flux.
In the end, I use the Weber kettle with an SNS Slow and Sear the most, as the fuel consumption is the least, access is best, the working height is comfortable and clean-up is easy. Next I use the 18 WSM, in which I can hang.
The 22 WSM is rarely out of the garage, even though it can grill, smoke or hang. It's a once a year occurrence for maybe a large packer brisket.
If I was feeding small groups, I'd pick the Weber kettle and an 18 WSM with a round Hunsaker hanging rack and a Cajun Bandit extension section to increase head space to hang.
