RS2

Key points

Minimalism: Highly effective for selective trout rising during heavy, technical hatches (such as BWOs or PMDs).
Vulnerability: Mimics the insect during the brief window when its wings are wet and folded.
Tying: Uses beaver or synthetic dubbing and micro-fibetts tails for a clean silhouette.
