I have an XL BGE, and love to use it for indirect cooking. I find that it is very difficult to get it up to temp in anything less than 30 mins with the placesetter. I previously heard that the BGE absorbs so much heat that putting it in cold will drop the temp quickly and will make it hard to get up to cooking temp. So, I started inserting it immediately after the charcoal was lit, waiting a few minutes, and then closing the dome. Still, it takes a terribly long time. My second thought was that maybe I don't have enough fuel in the firebox, but that doesn't seem to make much difference either. Any thoughts?
