V's Tungsten Diver Damsel Barbless is a versatile, electric-blue damsel-style nymph with a tungsten bead and soft partridge hackle. The bead drives the fly down quickly, while the hackle provides movement during pauses and a controlled retrieve.
Fish it around stillwater weed beds and deeper margins, allowing it to sink before twitching it close to the bottom. A slow figure-of-eight gives a steadier damsel-like action. The bright blue is an attractor trigger, so reduce retrieve speed if trout follow without taking. It is tied on a strong Ahrex hook. Give it time at the right depth and be ready for the rod to lock up.
