The Cortland 333HT WF10F Rocket Taper / Green Line / New Old Stock is a high-quality fly line with specific characteristics that cater to anglers looking for performance and durability. Here’s a breakdown of its key features:

1. Cortland 333HT (High-Temperature) Series:
– Designed for durability in warm conditions (e.g., tropical saltwater or hot summer climates).
– Resists softening and retains stiffness better than standard lines when exposed to heat.

2. WF10F (Weight Forward, Floating 10-Weight):
– Weight Forward (WF): Optimized for longer casts, with a heavier front section to load the rod efficiently.
– Floating (F): Stays on the water’s surface, ideal for dry flies, poppers, and saltwater applications.
– 10-Weight: Suited for larger fish (e.g., tarpon, bass, pike) or windy conditions.

3. Rocket Taper:
– A specialized weight-forward taper with a short, aggressive front section for quick loading and powerful turnover of large flies or wind-resistant patterns.
– Great for punching casts into the wind or targeting fast-moving fish.

4. Green Line:
– The classic Cortland “pea green” color, which is highly visible in most conditions but not overly bright (good for not spooking fish).

5. New Old Stock (NOS):
– Indicates the line is unused but from an older production run (possibly discontinued or vintage).
– Cortland 333HT lines are well-regarded, so NOS can be a great find if the line has been stored properly (no cracks, sticky coating, or memory issues).

Best Uses:
– Saltwater fishing (bonefish, tarpon, permit, striped bass).
– Big freshwater species (pike, musky, large trout with streamers).
– Windy conditions where extra power is needed.

Care Tips for NOS Fly Lines:
– Inspect for cracks or stiffness (older lines may need conditioning).
– Clean with mild soap and water, then apply a fly line dressing if needed.
– Store away from UV light and extreme temperatures.

If you’re looking to buy or sell this line, its value depends on condition—unused NOS in good shape can be desirable for anglers who prefer classic Cortland performance. Let me know if you’d like help evaluating it further!
