Cornell and Diehls Montford Point Marine is the most flavorful, most "grab you by the front of the shirt and kick the living crap out of you while it nails your girlfriend and steals your lunch money" blend. Seriously. I could only smoke tiny bowls of that stuff, and even when I did I had to take one or two breaks throughout the bowl from the nicotine buzz. Safe Harbor Flake, also by Cornell and Diehl, is pretty tasty and has a good nic kick too. MacBaren Golden Extra is a good choice too.
