I can find a good smoke in many genres of blends or single leaf, but now and then I run up on a blend that is too harsh to be flavorful. I'm not talking about tongue bite, though sometimes that comes with it. I'm talking about a flavor that just tastes like bite. I've run into this with a Mac Baren blend or two, one a mixture of about eight tobaccos, years ago, that I haven't seen since. I got a little of that with Half-and-Half which surprised me since most of the codger blends are pretty friendly. Have you come upon blends that just seem to have an unfriendly attitude? Interestingly, this doesn't usually happen with strong blends; they're strong but not harsh usually.
