From my expirience the trout stocked in Pennsyltucky ain't too bright. I mean they are fish - trout even but I guess no one ever told them what the real trout is supposed to do. For firat few days after stocking I mostly use streamers. Sometime I will tie a midge of very small nyph as a dropper. Most hits will come on the streamer. After few days I will start switching to more and more nymphs and even some dries.
I gues it takes few days for the fish to switch from ground horse diet to the food real trout is supposed to eat...

And when it all fails then you can always join taboons of power bait fisherman...
