# **How to Choose Scientific Anglers Dacron Fly Line Backing (100-yrds)**
As an angler, selecting the right fly line backing is crucial for ensuring a successful and stress-free fishing experience. **Scientific Anglers Dacron Fly Line Backing (100-yrds)** is a trusted choice among fly fishermen for its durability, strength, and reliability. In this guide, we’ll explore the key factors to consider when choosing this backing and why it stands out in the market.
## **What Is Fly Line Backing?**
Fly line backing serves as an extension to your fly line, providing extra length when a strong fish makes a long run. Without backing, you risk losing your entire fly line—and potentially the fish—when a powerful species like salmon, steelhead, or saltwater gamefish takes off.
**Scientific Anglers Dacron Backing** is made from high-quality Dacron polyester, known for its abrasion resistance and low stretch. The 100-yard spool ensures you have ample line capacity for most freshwater and light saltwater applications.
## **Key Factors to Consider When Choosing Dacron Backing**
### **1. Strength & Diameter**
The **20-lb test** version of Scientific Anglers Dacron Backing is ideal for most fly fishing scenarios. It’s strong enough to handle large fish while maintaining a thin diameter, allowing more backing to fit on your reel. Thinner backing means greater line capacity, which is essential when battling hard-fighting species.
### **2. Material Quality**
Unlike cheaper alternatives, **Dacron polyester** is highly resistant to UV damage, saltwater corrosion, and abrasion. This ensures long-term performance, even after repeated use in harsh conditions.
### **3. Knot Strength & Reliability**
One of the biggest concerns with backing is knot security. Scientific Anglers Dacron Backing holds knots exceptionally well, whether you’re attaching it to your fly line with an **Albright knot** or securing it to your reel with an **arbor knot**.
### **4. Reel Compatibility**
Before purchasing, check your reel’s capacity. A **100-yard spool** is typically sufficient for most freshwater setups, but if you’re targeting big-game saltwater species, you may need additional backing.
### **5. Color & Visibility**
The bright **white color** of this backing makes it easy to track when a fish is running, helping you manage line tension effectively.
## **Why Choose Scientific Anglers Dacron Backing?**
– **Proven Durability:** Resistant to wear, UV rays, and saltwater.
– **Smooth Performance:** Minimal memory and tangling.
– **Trusted Brand:** Scientific Anglers is a leader in fly fishing innovation.
## **Final Thoughts**
When selecting **Scientific Anglers Dacron Fly Line Backing (100-yrds)**, consider your target species, reel capacity, and fishing environment. Its strength, reliability, and smooth performance make it an excellent choice for both novice and experienced anglers.
