By "yellow" do you mean sulphers? Light Cahills? IAE- for trout I go in to Cade's Cove to park and then hike as far as possible (Horseshoe bend?) and then wade and fish upstream back to the car. Is that correct? Abram's is supposed to be "the stream" since it is a limestone. I was also thinking about the Middle Prong of the Little River- how would the two compare to one another? Thanks.
BTW: I've read that a dry and nymph combo works well, maybe a #12 Light Cahill and #16 PT nymph. Have you tried it and does it work well?
