I'm from Western PA also. I generally use spinning outfits and rooster tails early in the season, but I think I'll go with flies this year. I fish stocked rainbows in Thorn, Buffalo, Connoquenessing, and Bonnie Brook. I fish Thorn the most and it is mostly mud bottom, with some brush. It averages about 3 feet, with some riffles. In the past, I'va caught trout there using wolly buggers, mickey finns, and copper johns, and Clouser minnows in the pools. I've found that in the evening they bite grasshoppers really well. Hope this helps.
