Don't overlook the North River as well. Nice campground up there right on the water. I usually fish the North River and maybe see 2 other folks on it on a crowded day.
As for flies, Elk Hair Caddis, Royal Wolf and Stimulator (I actually use a the yellow sally stone pattern (from Dave Hughes Essential Trout Flies), very similar to the Stimulator, just smaller with out the palmer hackle). All sized 14 to 18, with 16 being my first bet.
On nymphs, of course you have to use a Tellico Nymph up there, prince nymph, hairs ear, black / yellow stones, olive / green beadheads / caddis larvae work. Sames sizes.
You can also drop a small brassie off of the drys.
