Fly pattern
Mass Attack
Howard Croston's custom caddis dry pattern. Designed by the 2019 World Champion, this pattern utilizes a foam strip and deer hair wing to float high in turbulent rivers, acting as a highly visible indicator fly for dry-dropper setups.
Key points
•
Flotation: A foam strip underbody keeps it dry and floating even when dragged by heavy droppers.
•
Silhouette: Replicates the tent-winged profile of adult caddisflies.
•
Versatility: Equally productive on lakes and fast mountain streams.
