I use several - Happy Holla, KCRibDoctor, Pit Boss, DoubleQ, Blues Hog. There are a bazillion locally produced rubs on the shelves in KC stores. And several of them are better than any home made. I'm an admitted rub and sauce junky. Picked up some Blues Hog Red Sauce today, vinegary, peppery, sweet, gotta smoke a butt to try it on pulled pork.
KC Masterpiece anything doesn't work for me. Poor Q.
