# **How to Choose Scientific Anglers Dacron Fly Line Backing, 20lb / 100 Yards – White – 545458**
When it comes to fly fishing, every component of your setup plays a crucial role in ensuring a successful and enjoyable experience. One often overlooked yet essential part is the backing line. The **Scientific Anglers Dacron Fly Line Backing (20lb / 100 yards, White – 545458)** is a trusted choice among anglers for its durability, strength, and reliability. In this guide, we’ll explore why this backing line is an excellent option and how to choose the right one for your needs.
## **What Is Fly Line Backing?**
Fly line backing serves as an additional length of line that sits between your fly reel and the fly line. Its primary purpose is to provide extra length when a strong fish makes a long run, preventing the loss of your fly line. Additionally, backing helps fill the reel spool, ensuring smooth line retrieval and reducing memory coils in the fly line.
## **Why Choose Scientific Anglers Dacron Backing?**
### **1. Strength & Durability**
The **20lb Dacron backing** is strong enough to handle large freshwater and saltwater species, including trout, bass, and even tarpon. Dacron (polyester) is known for its abrasion resistance, ensuring it won’t fray easily when rubbing against rocks or structure.
### **2. Smooth & Tangle-Free Performance**
Unlike some cheaper alternatives, Scientific Anglers’ Dacron backing is tightly woven, reducing the risk of tangles and ensuring smooth casting and retrieval. The **white color** also makes it easy to see against the water, helping you track line movement.
### **3. Consistent Diameter & Reliability**
A uniform diameter ensures smooth winding on the reel, preventing uneven spooling that can lead to casting issues. Scientific Anglers maintains high manufacturing standards, so you can trust this backing to perform consistently.
### **4. Saltwater & Freshwater Compatibility**
Dacron is resistant to UV rays and saltwater corrosion, making it a versatile choice for all fishing environments. Whether you’re targeting steelhead in rivers or bonefish on the flats, this backing won’t degrade over time.
## **How to Choose the Right Backing for Your Setup**
### **1. Consider Your Target Species**
– **Smaller fish (trout, panfish):** 20lb backing with 50-75 yards is usually sufficient.
– **Large freshwater/saltwater fish (salmon, tarpon, stripers):** Opt for 20-30lb backing with 100+ yards for extra insurance.
### **2. Match It to Your Reel Capacity**
Check your reel’s specifications to ensure the backing and fly line fit properly. Overfilling can cause casting issues, while underfilling may lead to poor line retrieval.
### **3. Check Compatibility with Fly Line**
Ensure the backing diameter complements your fly line weight. The **20lb Dacron backing** works well with most 4-10 weight fly lines.
### **4. Knot Strength & Ease of Attachment**
The Scientific Anglers Dacron backing holds knots securely, whether using an **Albright knot** (for attaching backing to fly line) or an **arbor knot** (for securing backing to the reel).
## **Final Thoughts**
Choosing the right backing is just as important as selecting the perfect fly line or rod. The **Scientific Anglers Dacron Fly Line Backing (20lb / 100 yards – White – 545458)** offers strength, reliability, and smooth performance, making it an excellent choice for both beginners and seasoned anglers.
