Damned, I should have written "self-made rub", because I can't really try or compare all those mentioned commercial rubs, since they are not available here (I only have that one can of Yardbird, which I got as a present by a fellow brethren).
The butt glitter seems to be promising, but we don't have celery seeds and mustard powder, so I'll have to put that one on hold.
Smokey is already prepared for tomorrow's 3-way session, and the lineup still is
#1 Lemon Pepper
#2 Carolina PP Butt Rub (featuring cumin)
#3 Austrian "Schweinsbratl" (featuring caraway)
I know about the discussion rub or not, simple S&P (or the slightly more advanced lemon pepper) would do the job as well, but typical rubs definitely add to the overall experience, and there is no doubt about the bark when the rub contains sugar as well.
