Pat Dorsey's UV Scud
From Pat: "Scuds are an important food source for tailwater trout. I recommend carrying olive and orange UV Scuds in sizes 14-16. The good news is that scuds are wanted “dead or alive” so you can’t have too many!"
UV Scud Recipe:
Hook: TMC 2457 14-16
Thread: Orange or olive 6/0 Danville
Tail/antennae: Orange or olive Antron
Rib: 4X mono (try UTC mono as an alternate)
Shellback: Zip Loc Bag (try Hareline's Scud Back as an alternate)
Body: Orange or olive UV Dubbing (try Wapsi's Sow-Scud Dubbing as an alternate)
Legs: Pull the dubbing down with a bodkin. Trim the legs so they are even with hook point.
