It's just got to be Windjammer for me. Excellent VaPer that is robust and slightly boozy, but never harsh. Great out of tin, and benefits from age enough to make it jarring it for a length of time worthwhile.
But I would say that Barbary Coast is a close second for me. I'm a burley guy through and through, and BC scratches an itch that, for me at least, is fairly unique to it. I wish Gl Pease had more burley-centric blends, because the ones they do have tend to be quite good.
I'd also like to say that Stratford is a very underrated blend. Another great VaPer.
