I don't rub butts...:icon_devil Ok, let's start over; I don't use a rub on butts as I only use butts for Pulled Pork and it seems senseless to use a rub and them mix all the meat up. I do add some seasonings/rub to the AJ when I foil and hold in a cooler for an hour or so prior to pulling, then incorperate the AJ/rub/juices back into the PP. Ya get the flavor, but I think you get a more uniform incorperation...
For Chicken I love Plowboys Yardbird coupled with Todd's Dirt. If I wanna add some spice to my life I use Todd's Dirt and Weber's Kickin Chicken. I smoke 'em at about 240-250 in order to get a deeper longer smoke. Then I kick the heat up to 300-325 for the last 30 mins or toss on the gasser for ten minutes or so to crisp the skin.
