Craig, It sounds crazy, but as I told Chau earlier, I dont like burning money, which is what I equate burning wood with. I have no problem with the investments to get there, but when the fuel has little to no direct effect on the finished product, why spend the money. I have burned ash,red oak, maple, poplar, birch, hickory, apple, white oak, pine during warmup, and I am sure a couple others that are slipping my mind right now, and none have ever come close to giving me this wood tastes good, or this wood sucks. IMO it is nothing like BBQ, there is very very litle flavor contribution to a pizza given to it from the wood. When you get yours going you will see the line between smoke and superheated air about 5 inches off your oven floor. There is just no smoke there. As long as you wood is dry, and you have plenty of it, you should be happy. The one disclaimer I have is that there may be some noxious wood out there that I have not encountered that will add an undesireable tatse to pizza, but i have not found it. Thats all I got. -marc
