I haven't found anything that I care to stick to long term. Tried Plowboy's and thought it was very good, both BB and Yardbird, but you can't buy it locally here and I pretty much operate on a whim when it comes to rubs so I pick up whatever catches my eye when I go to the store. I always keep a couple of shakers of Fiesta Rib Rub in the pantry and it is sort of my fallback. My local HEB has started carrying a bigger selection of BBQ products (Blues Hog in particular), so I pick up a bottle here and there.
