Red dubbing with copper wire and soft hackle — the Welsh pattern name means 'red and black,' and it works because the people who tied it knew exactly what their rivers produced.
Fish this when
Spring and autumn on spate rivers in broken water. Fish it on the swing or dead-drift, working it through the current with gentle movement.
Why it works
Red and black are high-contrast colours visible in murky water. Soft hackle creates animation. Welsh rivers are limestone streams where this pattern is proven.
