My first batch was a mess with the bayou classic and having just cracked one I think I can trace some of the issues back to the boil (too high of boil and a minor boil over). With that said my second batch was a little better. I had the tank regulator cranked wide open with a half twist back, then I set the air flow apperature to have the most constricted setting, then managed temp with the valve on the connecting hose. This allowed me to get to a boil quickly and maintain a rolling boil.
But I doubt there is any magical combination to the three. So, set two them and tweak the last for control.
