Thought I would share a pattern I have great success with locally. It has been very deadly in the spring and summer on slower waters. I would think it could work well on some sections of the Clinch. I fish this both as a emergent and like a small wet fly.
Hook: Mustad 3906 size 18 - 12
Tail: 3 strands moose mane
Body: Built up with muskrat then covered with stripped peacock hearl
Thorax: Peacock hearl
Wing: 2 grizzly hackle tips
On the fly pictured I tied the tail about twice as long as called for. I do this on this fly about half the time. I think it works as a trigger point.
