Barry, WFOs have a multi-directional heat aspect that produces slightly better NY pies than home ovens, but, with your setup, you can make something very close to this. And, although you can obviously get these results without bromated flour, as you're seeing Marlon doing, if you do have access to bromated flour, use it. I don't know how long Marlon's been doing this, but getting this kind of crumb with unbromated flour isn't something you achieve overnight. Bromate will trim that learning curve considerably.
