Hung out with my brother on Saturday night. He's been using a NBBD for almost a decade. Asked him about the need for even heat across the grill. He said "There are advantages to having different heat zones!" He feels that having the ability to increase or decrease the heat applied to a particular piece of meat without having to mess with the overall temperature of the smoker is a big advantage. He gets the approximate temp he wants, then when it's mop time he rotates pieces to different parts of the cooking surface. And I gotta tell ya, his BBQ is great. So... I see so much effort on these forums devoted to evening out the temperature. Are there any long-timers here who prefer uneven heat, who see it as useful & beneficial?
