The Cortland 555 Quick Descent Fly Line is a specialized fly line designed for fast-sinking performance, making it ideal for targeting fish in deeper water columns. Here are the key features and details:
Key Features:
1. Fast-Sinking Design – Typically sinks at a rate of 5.5 to 6 inches per second (IPS), allowing quick access to deeper fish.
2. Durable Coating – Made with a high-density polymer coating for smooth casting and long-lasting performance.
3. Low-Stretch Core – Enhances sensitivity for better strike detection.
4. Weld-Looped Ends – Easy attachment to backing and leaders.
5. Versatile Use – Great for streamer fishing, deep nymphing, and saltwater applications where a fast sink rate is needed.
Specs:
– Available Weights: Ranges from 4WT to 12WT (varies by model).
– Length: Standard 90-foot length (30-foot head on some models).

– Color: Often dark green or black for low visibility underwater.
Best Uses:
– Streamer Fishing – Quickly gets flies down to trout, bass, or pike.
– Deep Nymphing – Effective for Euro-nymphing or stillwater presentations.
– Saltwater – Useful for striped bass, redfish, or other species holding deep.
Pros:
✔ Fast sink rate for deep presentations
✔ Durable construction
✔ Smooth casting performance
Cons:
✖ Not ideal for shallow water or surface fishing
✖ Requires proper retrieval techniques to avoid snags
Alternatives:
– Rio InTouch Depth Charge (similar fast-sinking line)
– Scientific Anglers Sonar Sink 25/30 (for even faster sink rates)
