I just saw Weber Rub in the store for first time and picked it up.
They only had BBQ Sweet and Tangy. I tried it on Pork Chops and it tasted pretty good. I like the some of the pork rubs I make better, but it was a nice blend.
I've used a lot of thier seasoning mixes. The Chicago Steak is good and the Savory Salmon is excellent. You can get the marinade packets at Sam's pretty cheap, and they are very good too.
