What Our Gearhead(R) Experts Are Saying:"I fished the X-Fly Parachute Mayfly Assortment through a full BWO hatch, from the first adults hatching to the spinner fall at dusk, and never had to swap patterns. The hi-vis parachute made it easy to track even as light faded."A full mayfly hatch runs through several distinct stages, and the Rainy's X-Fly Parachute Mayfly Assortment is designed to match every single one of them without forcing you to switch flies mid-float. We love fishing a pattern this versatile, whether trout are eating a freshly hatched adult, an egg-laying female, or a spent spinner drifting lifelessly on the surface. The tail relies on Rainy's Mayfly Tube Bodiz for a realistic silhouette that also happens to be hollow, helping the fly float naturally on the water. A hi vis foam parachute and hackle add extra buoyancy and visibility, and with a couple of sizes each in BWO, PMD, and Adams Gray, six flies cover the major mayfly hatches as both a specific match and a general attractor.
