No stone yet, can't find one that I like. Looking for one that's at least 16", most that I see are 14 and too thin.
For now I use a round pizza sheet and precook the skin for 1 minute (I know, blasphemy).
I'll probably get a stone and peels after the kitchen's done.
I do like that grate you have your pizza on. Hate it when I put the pizza on the counter and the underside gets soft.
Some guys have luck with a steel plate cut to size.
Yeah the cooling grate is nice when doing more than one pizza. Keeps it from getting soggy.
