So we are moving in a few weeks so just doing research right now. I have been making pizza in my Performer with darn good results. Only thing I have been doing is raising the stone about the grate. I do plan on purchasing a Pizza Que but I got to thinking about another option - what about putting the Pizza Que on my WSM with the charcoal raised up to the lower level just below the top grate. I ask this because I hear about the rollers melting on the Performers. Problem is maybe that my WSM is the 18" model, is that too small for the fire to get around the stone?
