# **How to Choose Fly Fishing Line Backing: Terylene Fly Line & Braided Backing Line (20/30 LB)**
Fly fishing is an art that requires precision, patience, and the right gear. One often overlooked but essential component of your setup is the **backing line**. Whether you’re targeting large trout, salmon, or saltwater species, choosing the right backing can make a significant difference in your fishing success. In this guide, we’ll explore the differences between **Terylene fly line backing** and **braided backing line (20/30 LB)**, helping you make an informed decision for your next fishing adventure.
## **Why Do You Need Backing Line?**
Backing serves two primary purposes in fly fishing:
1. **Extra Line Capacity** – Fly reels have limited space, and backing provides additional length in case a strong fish makes a long run.
2. **Improved Reel Performance** – Proper backing ensures your fly line sits at the optimal position on the reel, preventing slippage and improving retrieval.
Without backing, you risk losing both your fly line and a trophy fish.
## **Types of Backing: Terylene vs. Braided**
### **1. Terylene Fly Line Backing**
Terylene (also known as Dacron) is a **synthetic polyester material** widely used in fly fishing backing due to its durability and affordability.
**Pros:**
– **High Strength-to-Diameter Ratio** – Offers excellent strength without excessive bulk.
– **Low Stretch** – Provides better hook-setting power compared to nylon.
– **UV & Abrasion Resistant** – Holds up well in both freshwater and saltwater conditions.
– **Smooth Winding** – Prevents tangles and ensures smooth casting.
**Best For:**
– Anglers who need a **reliable, budget-friendly** backing option.
– Freshwater fishing where extreme strength isn’t always necessary.
### **2. Braided Backing Line (20/30 LB)**
Braided backing is made from **high-performance polyethylene (HDPE) fibers**, such as Spectra or Dyneema, offering superior strength and thin diameter.
**Pros:**
– **Extreme Strength** – 20-30 LB braided backing can handle powerful saltwater species.
– **Thinner Diameter** – Allows more backing on the reel compared to Terylene.
– **Near-Zero Stretch** – Ensures solid hook sets and better control over big fish.
– **Knot Strength** – Braided fibers hold knots securely, reducing break-offs.
**Best For:**
– **Saltwater fly fishing** (tarpon, bonefish, permit).
– Anglers targeting **large freshwater species** (steelhead, salmon).
## **How to Choose the Right Backing for Your Needs?**
### **1. Consider the Fish Species**
– **Small trout/panfish?** Terylene (20 LB) is sufficient.
– **Saltwater gamefish?** Opt for **30 LB braided backing** for extra security.
### **2. Check Your Reel Capacity**
– Braided backing takes up less space, allowing more yardage.
– Terylene is bulkier but works well for standard freshwater setups.
### **3. Knot Compatibility**
– Terylene is easier to knot (Albright, Arbor knots work well).
– Braided backing may require **specialized knots** (e.g., Bimini Twist).
### **4. Budget vs. Performance**
– Terylene is **more affordable** and great for casual anglers.
– Braided backing is **premium-priced** but offers unmatched strength.
## **Final Thoughts**
Choosing the right backing line depends on your target species, reel capacity, and budget. **Terylene backing** is an excellent all-around choice for freshwater anglers, while **braided backing (20/30 LB)** is ideal for saltwater and big-game scenarios.
