I first got the 18.5"wsm and then kind of wished that i had gotten the 22.5"wsm. Mostly because of the rib thing, had to cut or roll. But then i really came to really liking the 18.5"wsm. It good at doing small amounts of food, but can handle cooking a lot too. I've done 8 butts at one time with mine. I've also done a 17# brisket too. Then I saw a 22.5"wsm on Craigslist for $300, and talked the guy down to $260. So now i have both! The more i use the 22.5"wsm the more I like it. I really like the extra space, it really doesn't use a ton more charcoal like i thought it would. I started cooking for church bbq's and stuff so the 22.5"wsm is a good investment alongside the 18.5"wsm, but if you're not going to be doing something like that, I'd say the 18.5"wsm might be a better way to go. Let us know what you go with!
