I picked up some Bad Byron's Butt Rub yesterday, along. Hearing mixed reviews about it, I was hoping I would find it on the positive side. Using the Smokenator 1000 and Kingsford Charcoal along with pecan chips, I put a small butt (3.6lb) onto my Weber Kettle charcoal grill. Using my Maverick ET-732 thermometer, I was able to keep my temps between 230-240 degrees. I foiled the butt once it hit 170 degrees and when it hit 203 degrees (total cook time was just under 6 hours), I wrapped it in a towel and placed it into my cooler for close to an hour. I was able to pull it apart rather easily and have to say that I was pleased with the rub.
Here's my Q-view:
