Old Joe Krantz will make you cry for mercy. Bayou Morning has a decent amount of nic. Exclusive and Exhausted Rooster are also candidates, but I have not tried them. I think Exclusive is similar to Bayou Morning, but with double the perique content. I have not tried Irish Flake yet either, but I have had Sterling Flake which is supposedly similar but did not seem too strong to me. Irish Flake is rated as being a bit stronger. Along with Jack Knife Plug, I really enjoyed Triple Play which has perique. Dark Birdseye is also a good Kentucky blend. Since I am rationing my Old Dark Fired, I have started dabbling with the Italian dark fireds. Sinfonia is one I really enjoy from Toscano.
