I'm also a fan of the Simply Marvelous rubs. You can even buy a sampler that has five different flavors, and the containers hold enough to last you a while. All that I've tried so far have been great. Even the spicy rubs on the list have a touch of bite, but nothing severe at all. And, if you do decide to make it hotter, just add some cayenne.
