Well, I haven't fished the Smokies yet, but since my plan is to fish small streams, I'm planning on going small. I love glass rods. I'm planning on bringing a 6'6" Eagle Claw Featherlight 4/5wt and my favorite rod, my Fenwick FF85 7'6" armed with a Medalist 1492AK. This should cover me for tight brushy streams and medium streams as well.
I am in the market for a short 3wt glass rod. I don't know if it's in the budget before my trip but I sure hope so.
