For a little pop, you can take the same rubs you are using and grind them super fine, then use them as a finishing dust. Have you tried the Blues Hog Raspberry Chipotle sauce? My Ace Hardware has a great BBQ rub and sauce section and they carry Blues Hog and Plowboy's Yardbird.I really liked the flavor of the wings and the skin was close to perfect. It had a buttery bite through feel. It got a bit leathery on the ends though.
These wings turned out very well and had a pleasant heat on the back end. Just lacked some pop. Not quite sure what that might be. I am trying Blues Hog sauce on my next attempt.
