FWIW, there are a few blends I keep around because I really like the flavor (what little there is) and aroma but they just seem like an airy, watered down smoke. (Incidentally, all of them are Cavendish blends.) It's like you're sucking warm air with the tiniest hint of flavor. These are the ones where I mix a coin of some vaguely similar SG rope in with a bowl of said tobacco. Seems to do the trick almost every time. So what I'm driving at is if you try it a few times and there's no hope for it, try adulterating it with a little rope.
