I love fly fishing for smallies, and do it a lot.
I use a 6, 7 or 8 wt. rod depending on conditions and how big a fly I want to toss.
I've become a fan of Temple Forks rods, though about half my rods are St. Croix.
I also really like Lamson reels - very often close to if not the lightest for the size, great drag and not over-the-top pricing.
Lines are kind of whatever works - I have an Airflo streamer on one rod, A Rio Clouser on another, a Scientific Angler Hover line on another, a Rio Versitip on my 10 ft. 7 wt. and a Scientific Anglers GPX sinking line on one of my 8 wt. rods...horses for courses...
Flies...I'm not a fly fishing purist, so I try to learn from what works when I throw gear...so a lot of my ties resemble what works there - I tie baitfish that look like Rapalas, crayfish looking flies that resemble plastic baits, and use a lot of common flies like woolly buggers, poppers and things like that.
Consider Thin Mints in larger sizes, and Take a look at a Slump Buster...but then tie it bigger.
