I have a Cimarron also, and the 'gas assist', from my experience, is absolutely no good for keeping temps. The fire comes out nice and ORANGE, which means serious creosote issues. Unless I'm ready to toss the meat, I would not use the "Log Lighter" for anything but firein' her up.
KC, you've got the 'Deluxe' - very nice!
