Just got a bbqguru this week and am going to get a butt on the BGE tonight. I think I understand how it works, but I have a question about how I set the daisy wheel on top of the egg. For a normal slow and low cook, I keep it open only 1/2-1 centimeter. From reading the directions, it appears that I should be keeping it open more with the DigiQ II. Any experience here? Also, if you do keep it open wider, do you do that after the initial smoking period?
