i like darker flies in the winter time. bwo nymphs, black fly larva, black zebra midges, small black caddis on the watauga, brown san juans, pheasant tails, etc. of course, most of these flies are in the summer/spring arsenal as well. the bwo nymph is my go to soho fly, followed by the black fly larva for the flat water sections.
