One exception to the blended overly moist rule of thumb are my blends, available from 4noggins. I purposely created them to be drier than other blends, since I've found that drier tobacco smoked better, and offers more flavor when smoked slow. In fact, if you try one of my blends, smoke a few bowls As IS. Then, if you feel it's too dry, load your pipe, cup your hand around the bowl, and breathe into the bowl 4-6 times. This should result in the perfect moisture level. Normal rehydration methods will ruin my blends.
