I have had great success with the blends- I like the Bold & Sweet BBQ's. I can for sure taste different profiles. The Gromet didn't taste all that unique to me. Haven't tried Savory or Bourbon yet. I am for sure going to get some bourbon, as my wife and I make a smoked bourbon caramel chocolate cake- and I want to try cooking the whole cake on the smoker!
I also enjoy just getting several bags of the single woods, and blending them myself. For briskets and beef, I do oak, mesquite, hickory, and a little pecan (from another brand). For a lighter taste, I've done maple and apple, with some oak or alder in there.
Their descriptions on the website, and recommended meat pairings, are pretty helpful. You can't go wrong with some hickory and oak to start out with.
