# **How to Choose Scientific Anglers XTS Gel Spun Backing – 50lb / 500 Yards – Yellow – 673069**

As an angler, selecting the right backing for your fly reel is crucial for maximizing performance, especially when targeting large, hard-fighting fish. The **Scientific Anglers XTS Gel Spun Backing** is a top-tier choice for anglers who demand strength, durability, and reliability. In this guide, we’ll break down why this backing stands out and how to choose the right one for your setup.

## **Why Choose Gel-Spun Backing?**
Backing serves two primary purposes:
1. **Extra Line Capacity** – It fills the spool so your fly line can be properly loaded.
2. **Insurance Against Big Fish** – When a powerful fish makes a long run, backing prevents you from being spooled.

Traditional Dacron backing is common, but **gel-spun polyethylene (GSP)**, like the **Scientific Anglers XTS**, offers superior strength-to-diameter ratio. This means you can fit more yards on your reel without sacrificing breaking strength.

## **Key Features of Scientific Anglers XTS Gel Spun Backing**

### **1. Exceptional Strength (50lb Test)**
With a **50lb breaking strength**, this backing is ideal for saltwater species (tarpon, tuna, sailfish) and large freshwater predators (musky, steelhead, salmon). Unlike Dacron, GSP doesn’t absorb water, maintaining its strength even after prolonged exposure.

### **2. Ultra-Thin Diameter (500 Yards Capacity)**
The **high-density polyethylene fibers** allow for an incredibly thin diameter while retaining strength. A full **500-yard spool** ensures you have enough line for long runs, even on mid-sized reels.

### **3. Bright Yellow Color for Visibility**
The **vibrant yellow hue** makes it easy to track line movement, helping you monitor fish runs and detect subtle takes in low-light conditions.

### **4. Smooth, Tangle-Free Performance**
The **XTS coating** reduces friction, ensuring smooth casting and retrieval. Unlike cheaper backings, it resists kinking and abrasion, prolonging its lifespan.

## **How to Choose the Right Backing for Your Setup**

### **1. Match Backing Strength to Your Target Species**
– **30-50lb**: Ideal for large freshwater and inshore saltwater fish.
– **50-80lb**: Best for offshore pelagics (tuna, marlin).

The **50lb XTS Gel Spun** is versatile enough for most big-game scenarios.

### **2. Consider Reel Capacity**
– **Large-Arbor Reels**: Can hold more backing due to wider spools.
– **Standard Reels**: May require thinner backing (like XTS) to maximize yardage.

Always check your reel’s specifications before purchasing.

### **3. Knot Compatibility**
Gel-spun backing can be slippery, so use **non-slip loop knots** or **Bimini twists** for secure connections to your fly line.

## **Final Verdict: Who Should Use This Backing?**
The **Scientific Anglers XTS Gel Spun Backing – 50lb / 500 Yards** is perfect for:
– **Saltwater anglers** needing abrasion resistance.
– **Big-game freshwater fishermen** targeting long-running fish.
– **Anyone seeking a high-performance, low-diameter backing.**

For anglers who refuse to compromise on quality, this backing is a **must-have** in your tackle arsenal.
