For a while there I was really gung ho about pizza and doing many experiments. I am just one of the many members here who chose to document a lot of what I did back then. If you look, there are lots of very active members on this board making every style of pizza known to man. There is such a wealth of pizza knowledge on this forum. As you, I also benefit greatly from everyone's work. I can always learn something new from any thread, whether I want to or not. I hope that you continue to document what you are doing with your new oven. As long as you are having fun, which it sounds like, and there are friends to enjoy your pizza, then you are successful. We are all here for the same reason, a journey to better pizza and pizza nirvana. I myself, still feel like a beginner many days and struggle just the same. I'm not kidding.
Yes, tinker and mod the oven if you have to. If you are passionate about pizza, and it sounds like you are, you will find one way or another to keep tweaking and get better. I'm very excited to hear that there will be a wfo in your future. No matter what oven you end up with, you'll have fun learning how to get the most out of it. But let me just say that if you think that you may end up doing mostly NP pizza, then please do get a low dome oven. You'll find a way to make it work for the other foods you want to make in it. It will just be easier. Trust me. But if NP isn't your thing, then any oven will do. Having a low dome oven will just make doing NP easier.
As far as hijacking a thread, I am guilty of that many times. It is common on this forum, so don't worry about it too much. The mods will move things around if they need to.
