Norm, the bullet? I recently got a temp control fan for my 22" smokey mountain. Got the bbq guru digiQ. Brisket has been my favorite too.
I run the CyberQ, have been for many years... love it. I use that on a drum smoker, and used to use it on a weber kettle.
My Q buddy and teammate, and where I smoke mainly, has a 125g propane tank stick smoker, a Gateway drum smoker, Stumps stretch XL and a pit barrel. We're ramping up to do a 500g or so stick smoker build soon, well... two actually, one for him and one for my house.
what are you running? Lump or brickets? I'm gearing up to make my own lump out of almond and pecan soon. I want to have uniform sizing on my lump for a better and more controlled burn.
