What sort of bake time are you looking at? I know that in my regular home ovens I'm generally around a 7 minute bake which is frustrating when you have a crowd of people. Granted I can do two at once, because I have double wall ovens, both with stones, but still. With a WFO, the temperatures you can go with can achieve such a quick bake time, that you don't have to go with many at once.
I am in awe of the guys I've seen who can juggle 5 or 6 pies in a large WFO. But they know their ovens well, hot spots, wood conditions, to dome or not to, etc.
Well, I am envious!
