This is exactly what I'm saying,4 years ago I bought a pound bag of Smokers Pride and promptly soaked it in scotch,let it dry a bit and have been working on it since.In short I would say that any "crap" tobacco would be supplies for future mixes and blends.That is also why I agree with your other post on humidity measures,pipe smoking can be simple or you can make it a full fledged hobby and science.I would recomend reading the reviews and find flavor profiles that appeal to you and if you find you dont like one or two try to pick out what it is you don't like and try to find a mix to make it better.A little bit of chemistry is fun.
