Are you meaning blends we recommend as "must try" or blends we hope to try ourselves? Most of what I want to try involves time. I'm fascinated by how things change over time. Most of these "good" tobaccos get better with age as is so with cigars, wine, all sin stuff pretty much. I, however, do not get better with age which is why, I suppose, I like things that do.
My #1 want to try is Smokers Haven Krumble Kake, I've been told more than a few times that I "have to try it it"... enough times that I've come to agree.

Pretty much all the really good Virginia, VaPer, and Lat blends pre '80's
