I was just there this last weekend. The WMA was kind to me. 6 decent fish in the 4 hours I spend up there between Saturday evening + Sunday morning. Unicoi outfitters told me the lightning bug nymph was working so I got myself one. Caught me the biggest fish of the trip.
I don't know of anyone who does the guided trips for wild trout like Hunter did a lot of. But Unicoi has several good guides for private waters up that way. Good Luck.
