This fly worked exceptionally well on the Bighorn River during a mayfly hatch. The CDC material gave it a natural wiggle that attracted fish consistently. A reliable choice for nymphing in high mayfly seasons.
Sean Taylor –
I’ve used several nymph patterns in rivers with strong mayfly activity, and this one stands out. The movement under water is realistic and fish respond quickly. A solid addition to my fly box.
Alexandra Walsh –
Caught multiple trout on this pattern during a spring hatch. The undulation mimics the natural movement of mayfly nymphs, making it effective even in fast currents.
