Wow, surprised to see Margate listed here. I love it. ONe of my favorites.
As for h8ing a particular tobacco, I really didn't dig GL Pease Cumberland. The Virginias in it were OK, but the dark-fired Kentucky just made it harsh and unpleasant for my palate.
The only tobacco that I have honestly hated (and threw out) is McClelland's bulk "Special Black." It's a black cavendish tobacco with what I think is a vanilla/nut flavor. To me it tasted almost exactly like those incense sticks your hippie roommate burned in college -- all mushroomy and chemical-tasting. Yuk!
