One thing to keep in mind is if you change up air flow, you'll need to re-learn your settings. I got one of the Smokeware caps, and I'm sure adjusting it is different than the daisy wheel. I've only done 2 cooks, so there was no relearning. However, I am having a heck of a time dialing the thing in. Every adjustment I make seems to ping-pong the temp up or down 20 or 30 degrees.
