I use one of two. Either a 6.5 ft Orvis, 4 wgt or a 7.25 ft Bamboo, 4 wgt. I used to use an 8 footer, but I got hung up too often so I went to the shorter rods. I use the 8 footer and a nine footer(5 wgt) on the Clinch and when I go to Michigan.
As for reels I use an Orvis large arbor with two spools. One for dry flies and one for wets, nymphs and streamers
