I'm headed to the Smokies at the end of March (hopefully). My fly assortment is pretty slim. I only have about 24 or so. BWO, QG and a few Pheasant tails. What else would ya'll suggest I have?

Also, What about streamer fishing? I've been told that each big hole holds a big brown. I would like to hook up on a big trout. Would it be even feasible for a fairly inexperienced fisher, like me, to try streamer fishing for one of these? Or are there better options for the big one? Or should I stick with my nymphs and dries?
