I just purchased a KettlePizza, and asked Weber if the high heat would have any negative effect on the Performer. (Plastic table) Their response was that the KettlePizza was not a Weber Product, and they had no comment.
So, I bought a used kettle for my KettlePizza. Have, however noticed several photos of one being used on Performers?
(Guess it doesn't hurt to have a WSM, a Performer, and a Kettle for pizza and a rotisserie, eh?
