Very interested in this thread, as I'm looking for a new pizza oven myself. At my old house, I had a built in Chicago Brick Oven. It was wonderful for Neopolitan style, and fire roasted meats and veggies, but no question the 5 plus hours to get up to temp and heat in the bricks etc. meant it was kind of a weekend party trick...no where near used as much as I intended.
I don't want to derail the thread from the OPs's questions, but anyone have experience with so called hybrid ovens. Is it primarily one fuel or the other, or goes the gas help to get heat sink in the refractory faster, then you add wood for the flavor?
