Tomahawk - the 32 is a very well behaved cooker no matter the size of the cook on the grate. For small cooks, during the week, I just outfit my second basket with the basket splitter and I light up the lump! No big deal. Whether I'm cooking just a single chicken breast or I'm doing multiple turkeys, TheBeast is quite capable of answering the call. Of course, my 19, Beauty!, gets her fair share of small cooks as well. multiple KKs gives you a flexibility that most folks never get to enjoy. If I were to pick a starter KK and was on the fence about which to put on my patio first, I'd choose the larger size.
My motto has always been "Better to have the size and not need it than to need it and can't get it."
