Yeah, I like the rub on it's own. Has a nice sweet kick.
I've used too much salt in the past, but have adjusted my own rub to 2pt pep to 1 pt salt and just use less rub overall.
I love trying new ones but have yet to find one that WOWs me. I love starting out with a simple Santa Maria style base (like I listed in my OP) and then adding little touches to that.
