A Forums member sent me an admirable selection of samples of tobacco, and one of them is Old Dark Fired flake, Mac Barens I presume. I kept reading about these both in themselves and as part of other blends. The MacB version is Virginia and burley, and boy, is it good! I have a weakness for full-strength tobaccos, although I don't pursue them just for an experience or for high nicotine. This is just a fine, smooth, robust smoke that really follows through the entire bowl. It has real base notes but also a sweetness and timbre between the Virginias and the burley that is deeply pleasing. It may not be everyone's thing, but I think it will make a lot of pipe smokers happy. Full strength doesn't have to be harsh or intimidating. Go slow at first and find out how you do, but this might be a pleasant surprise.
