Here is my all time killer for Nymphing for trout in rivers and slaying Pan-fish in stillwater... I use my 3wt when casting it...sinks very slowly, tie it up size #12-16 and dub it up with course kip tail which makes it extremely buggy appearance, the buggier the better, make it with different types of tails... I guess it resembles a dragon fly nymph, stone fly or clinger nymph... I use 4 basic colors dark gray, brown, olive and black ...On Cape Cod, I troll on the numerous Kettle ponds with a float tube and extra long leader .... fish just can't stand it and have to inhale it
