I'm planning on buying a WSM soon and was wondering what current owners think of the 18in when it comes to smoking larger cuts. I smoke ribs, pork butt and brisket frequently and I've heard polarizing remarks about the 18in capacity. I only ask because there is an 18in for sale near me for $50. I know my query has an obvious answer but I couldn't resist lol. How well does a large rack of St. Louis' fit when flat on the grate, for instance? As always, thanks for the advice and patience with a question most have figured out!
