It really helps to think about how you are going to use it. There are just two of us, and the size is perfect. Even on those weekends when I have guests, I can make plenty. For the two of us, I do a lot of quick high heat cooks and the 14.5 is perfect for that - heat quickly and saves coal. For longer cooks with guests, I just do meat on the wsm and the sides on my weber kettle. I can easily do 4 or 5 racks of ribs using both shelves (I roll 'em but you can use Brinkman rack holders). I've done points and a holiday 12 pound bird as well. I would never do a whole packer as it is way too much food for us, even with dinner guests, and I don't have a separate freezer. I also don't think I would decide to just "fire up" the larger one for small meals, but I don't mind with the tiny wsm, so it gets used a lot. Having the kettle as a companion does give more options with company, though. Food for thought, I hope.
