I get pretty even heat in mine, but then I have a fire door built into the side and all I do is hit it with the weed burner and place the deflector on top of the basket. I had my deflector made from the lid of the drum. There is a simple rebar hoop on it for ease of lifting it in and out. I get good even heat throughout. I did ribs yesterday and managed to catch them right at the "weep" it was perfect.
