I don't know what my favorite would be, because I only have a few fly rods. My favorite set-up for panfish that I own is my 6-1/2 foot Eagle Claw fiberglass 5 wt, Scientific Anglers Dry Cell WF-5 line, and a 6' tapered leader (size doesn't really matter for panfish. They are not particularly line-shy, and are actually on the brazen side.....)

Someday, I would like to have a 3 wt. Even used would be OK.....
