# **How to Choose the VTG 1999 3M Scientific Anglers 20lb 100 yd. Fly Line Backing for Fly Fishing**
When it comes to fly fishing, selecting the right backing line is just as crucial as choosing the perfect fly rod or reel. The **VTG 1999 3M Scientific Anglers 20lb 100 yd. Fly Line Backing** is a classic and reliable option that has stood the test of time. Whether you’re targeting large saltwater species or powerful freshwater fish, this backing line provides the strength and durability needed to handle aggressive runs.
In this guide, we’ll break down the key features of this backing line, its benefits, and how to determine if it’s the right choice for your fly fishing setup.
## **What Is Fly Line Backing & Why Is It Important?**
Fly line backing serves two primary purposes:
1. **Extra Line Capacity** – Most fly reels don’t have enough space for just a fly line. Backing adds extra length (usually 100-300 yards) to prevent running out of line when a fish makes a long run.
2. **Shock Absorption** – High-quality backing, like the **3M Scientific Anglers 20lb**, helps absorb sudden surges from strong fish, reducing the risk of break-offs.
## **Key Features of the VTG 1999 3M Scientific Anglers 20lb Backing**
### **1. Superior Strength & Durability**
With a **20lb test strength**, this backing is designed to withstand the toughest fights. The **3M Dacron** material ensures abrasion resistance, making it ideal for saltwater species like tarpon, bonefish, and even large trout.
### **2. Smooth & Tangle-Free Performance**
Unlike cheap nylon alternatives, this backing is **braided for smoothness**, reducing friction and preventing tangles when a fish takes a long run.
### **3. Vintage Reliability (1999 Production)**
The **VTG (Vintage) 1999** label indicates that this backing was manufactured during a time when 3M’s Scientific Anglers division was producing some of the most trusted fly fishing products. Many anglers consider this era’s backing to be among the best ever made.
### **4. 100-Yard Spool Length**
A **100-yard spool** is sufficient for most freshwater applications. If you’re targeting bigger saltwater species, you may need to double up or opt for a longer backing setup.
## **Who Should Use This Backing?**
This backing is ideal for:
– **Trout & Salmon Anglers** – Provides enough strength for strong runs in rivers.
– **Saltwater Fly Fishermen** – The 20lb test is great for species like redfish, snook, and striped bass.
– **Vintage Gear Enthusiasts** – If you appreciate classic, high-quality fly fishing gear, this is a must-have.
## **How to Choose the Right Backing for Your Setup**
Before purchasing, consider:
– **Reel Capacity** – Ensure your reel can hold **100 yards of 20lb backing + your fly line**.
– **Target Species** – For larger fish, consider a higher-test backing (30-50lb).
– **Knot Strength** – Use an **Albright or Bimini Twist knot** to attach backing to the fly line securely.
## **Final Verdict: Is This Backing Worth It?**
The **VTG 1999 3M Scientific Anglers 20lb 100 yd. Fly Line Backing** remains a top choice for anglers who value **reliability, strength, and smooth performance**. While modern alternatives exist, this vintage backing offers a proven track record for serious fly fishermen.
If you’re looking for a **trusted, high-performance backing** that won’t let you down when a trophy fish strikes, this is an excellent option.
