There are no real secrets to fishing the Clinch, I grew up fishing this behind Wolf. Two flys is all a man really needs out there. Bead Head Pts and midges. Yes everyone knows about the zebra midges.
Try this out for a midge, black tungsent bead, with a olive V rib for a body. I tie and fish them also in black. you can put a little dubbing behind the bead if you wish, sometimes it makes a difference other times it doesn't matter.
Floro is a must and tungsten is worth the extra price.
