oh yeah, my top five:

Yellow(Perla) stonefly nymph
Snowshoe Caddis(tan,if I had to pick a color)
Snowshoe Sulfur(sulfurs are too numerous in PA,
this one gets used for 2 months)
Black Ant
Submerger(a scruffy soft hackle wet fly)

still, if you tried to part me from the other 760 or so patterns in my vest,
I would have to kill you.....
