Thanks for the comments guys!
Pizza_Not_War: Yeah, I was thinking about a wooden peel, but at the neapolitan pizza restaurant I worked at they used some kind of metal peel, maybe it was stainless steel... I am trying to stay true to what I know but maybe a wooden peel is the way to go.. I'll definitely take a look into that. Also the silicone mat is something I was considering, I'll also give that some thought. Thanks for your input!
Yael: I do have a scale, I am not certain how precise it is, its pretty cheap... In terms of peel size I was hoping to get large pizzas in there. I haven't gotten my oven yet so only time will tell how large of a pie I can fit in there ( I do get that you cant max it out completely) but I guess the idea was that I wanted to accommodate the maximum size of what can potentially fit in there..
I also understand that the dough trays need to be air-tight. The ones I was looking at had some complaints about that issue, but I have no idea if it their complaints are true across the board, or if the people that complained had some irregular ones. I guess ill find out if i get those dough trays.. thats really the problem with buying things online, who knows if the cheaper or even more expensive products will be satisfactory, right? I guess the answer you gave is pretty much what you'd expect.. more expensive products will probably give you more reliable results and vice versa.
Anyway, thanks for your input guys! I'll keep it in mind when I am shopping for stuff.
