# **How to Choose the Scientific Anglers Amplitude Smooth Redfish (Cold) Fly Line – WF9F – 138468**
When it comes to fly fishing for redfish in colder conditions, having the right fly line can make all the difference. The **Scientific Anglers Amplitude Smooth Redfish (Cold) Fly Line – WF9F – 138468** is specifically designed to enhance performance in chilly waters while maintaining the precision and durability needed for targeting redfish. In this guide, we’ll break down the key features of this fly line and help you determine if it’s the right choice for your next fishing adventure.
## **Understanding the WF9F Line Weight & Taper**
The **WF9F (Weight Forward, Floating)** designation means this line is optimized for quick, powerful casts—essential when targeting large, fast-moving redfish. The weight-forward taper allows for smooth energy transfer, making it easier to turn over bulky flies even in windy conditions.
– **Weight Forward (WF) Design**: Provides better distance and accuracy compared to double-taper lines.
– **Floating (F) Line**: Ideal for shallow-water redfish fishing, allowing flies to stay on the surface.
## **Cold Weather Performance**
One of the standout features of this line is its **cold-water formulation**. Standard fly lines can stiffen in low temperatures, reducing casting efficiency. The **Amplitude Smooth Redfish (Cold) line** is engineered with a specialized core and coating that remains supple even in chilly conditions.
– **Low-Memory Coating**: Prevents coiling and ensures smooth casts.
– **Enhanced Cold Resistance**: Maintains flexibility in water temperatures as low as 40°F (4°C).
## **Durability & Smoothness**
Scientific Anglers is known for its high-quality fly lines, and the **Amplitude Smooth series** is no exception. This line features:
– **AST (Advanced Shooting Technology) Coating**: Reduces friction for longer, smoother casts.
– **Textured Surface (Optional)**: Some anglers prefer textured lines for reduced friction, but the **Smooth version** offers a quieter presentation—ideal for spooky redfish.
## **Best Applications for the WF9F Redfish Line**
This line excels in:
– **Cold-Water Redfish**: Designed for fall and winter fishing when water temperatures drop.
– **Shallow Flats & Marshes**: The floating line keeps flies on the surface, perfect for sight fishing.
– **Windy Conditions**: The WF9F taper cuts through wind better than lighter lines.
## **How It Compares to Other Redfish Lines**
While many fly lines target redfish, the **Amplitude Smooth Redfish (Cold) WF9F** stands out due to its:
– **Superior cold-weather performance** compared to standard tropical lines.
– **Exceptional durability**—resistant to abrasion from oyster beds and rough terrain.
– **Optimized taper** for casting large, heavy flies with ease.
## **Final Verdict: Is This the Right Line for You?**
If you frequently fish for redfish in **cooler climates** or during **early morning/late season outings**, the **Scientific Anglers Amplitude Smooth Redfish (Cold) WF9F** is an excellent choice. Its specialized cold-water construction, smooth casting performance, and durability make it a top-tier option for serious anglers.
For those who fish in **warmer waters**, Scientific Anglers also offers a **tropical version** of this line. However, if cold resistance is a priority, the **138468 model** is the way to go.
### **Where to Buy**
You can find the **Scientific Anglers Amplitude Smooth Redfish (Cold) Fly Line – WF9F – 138468** at leading tackle shops or online retailers like **KyleBooker Fishing Gear**.
**Pro Tip**: Pair this line with a **9-weight rod** and a sturdy saltwater reel for the best performance.
