Unless I misread, no one has mentioned Robert Lewis 123 Mixture yet??? Fox's Bankers Blend? These are both extremely good Cigar Leaf blends that should be on anyone's short list of blends to try containing cigar leaf. GLP Robusto is also a great choice of course, particularly with some age. I have about a half pound left of the first run of Robusto from 2002 and I can say that at ten years old, this stuff is as smooth as a baby's bottom. Another decent one that no one has mentioned is Pipeworks&Wilke's Churchill. While milder than the others I have mentioned, Churchill has a very dry (not sweet) taste that reminds me of an earthy cigar like La Flor Dominicana makes.
