This one is tough, since my three favorites come from 3 different blenders, and the 90 or so other tobaccos I like come from everywhere. Ultimately, in terms of choices, I would go to McClelland. But believe it or not, Tinderbox sells 3 of the blends I smoke most often, so if I could only get one brand forever, it would have to be Tinerbox: 1928 Special Reserve, Connoisseur, and Philosopher.
Now that may change to Sterling, since I am getting attached to Double Eagle and 1776 Tavern Blend. Where are those decision dice, anyway?
