Agreed!I wouldn't totally rule out Kentucky, give it time.
I really didn't like HH Old Dark Fired. It was like smoking clods of earth that had diesel spilled on it. Grim. I didn't even managed to finish the bowl.
However, Coniston Cut Plug Unscented is a semi-regular one for me, and that's 75% dark fired.
Likewise, many Virginias taste of nothing, almost like hot air to me, but some are excellent. For me, Full Virginia Flake was tasteless, but Germain's Brown Flake is superb. Writing off whole genres because of one or two disappointing blends could rob you of some favourites.
