Have you ever seen a square horizontal smoker with a flat roof?
I never have.
Its an interesting discussion, I dont know who is right or wrong
I have a hexagonal offset stick burner that has a flat roof. I love it. I have never had any black stuff fall the top. I also have a rack in the middle. It's much hotter up top so it acts like a broiler. Great for setting sauces.
