Thin Mint Tungsten Bead - A favorite. Cast it to the bank, strip it back and see what happens! Widely effective for trout, char, salmon, bass and bream. It sinks fast! You can also jig it slowly in stillwater. You should have some of these in various sizes in your box.
Use this fly when nothing else works and always pick up fish. Great on trout and smallmouth bass.
Previously only found this fly in this quality at LL Bean but at $1 more per fly. Will be purchasing from DiscountFlies from now on.
