I have the 18.5 wsm and do alot of overnight cooks! I have the cyberQ and it works great at maintaining temp steadily. Sure beats getting outta bed to go outside and check the temp status.
I also just installed a nomex gasket set to further seal any leaks, with my cajun bandit door I put on last year, which is way better than original. Only downside to cyberq is occasional the interference I get (may look into a better router sometime). I also did the temp probe eyelet mod with the lamp post trick! Awesome!
BTW... it's so nice... I feel like I'm cheating!!! LOL!
