Any of the GL Pease Old London series tops on my list, in particular Sextant and Meridian. Mac Baren Latakia Flake and Vintage Syrian are both very good, IMO, and the Captain Earle's blends are richly deep and incredibly complex.

In somewhat related news, I tried my first bowl of the new Lane Andullo today - Cigar Leaf, Latakia, and a touch of anise in the blend. Not a lat-bomb, but plenty tasty.
