Ray - it's definitely worth a try...
Our first go at using it was last year at the Pork expo QLossal. We shot up our butts and our whole hog with Butcher and wound up with a 2nd place hog and 3rd in pork.
There are pretty good teams using this stuff including the Butcher BBQ team itself which scored 1st in pork at the Jack last year. Give David a ring...great product and really top notch customer service.
