Ever since Cortez let me know I'd like it (and he knows my tastes well!), I've been wanting to get my hands on some Peterson Hyde Park. I'm planning on adding to my next order. I usually smoke flakes, but I've been wanting a nice Lakeland style ready-rub that is easy and quick to load. Dark Bird's Eye usually fit that bill for me, but it is too strong (even for me) to be an all-day smoke. I find it stronger than Irish Flake, both in nicotine and flavor, and really only like to stockpile tobacco that can be smoked all day, since I leave the house with only 1 blend, which I will smoke all day.
Irish flake is a good suggestion, and so is Peterson 3P perfect plug. Both are very strong, but with the 3P, you can shave it off very fine, and rub out, which will fill your pipe with less tobacco, and not overload you as easily with nicotine. I do this often, and it really satisfies for a great smoke.
