Best to keep the Mrs happy. Nothing stresses out a woman in party planning mode more than having to keep pizza hut on the stand by for a dozen or so pizzas.
Nothing against experimenting before hand though. If you can fit in a small hog cook before hand then give it a go. If you're comfortable with a hog cook after that then give it a shot for the party but if not best to keep to what you already know and have experience with.
