# **How to Choose Fly Fishing Fly Line Backing: 30lb Test, 100 Yards (30.3 Metre) Spool “Dac Back”**
Fly fishing is an art that requires precision, patience, and the right gear. One often overlooked but essential component of your setup is the **fly line backing**. If you’re targeting large, powerful fish, having the right backing can mean the difference between landing your dream catch and losing it to a snapped line.
In this guide, we’ll explore how to choose the best **30lb test, 100-yard (30.3-metre) Dacron backing spool** for your fly fishing needs, ensuring you’re well-equipped for your next adventure.

## **Why Do You Need Fly Line Backing?**
Backing serves two primary purposes:
1. **Extra Line Capacity** – Fly reels have limited space, and backing provides additional length when a strong fish makes a long run. Without it, you risk being spooled (running out of line).
2. **Shock Absorption** – Quality backing helps absorb sudden bursts of energy when a fish surges, reducing stress on your fly line and leader.
For **30lb test backing**, you get a strong yet manageable line that balances durability and flexibility, making it ideal for freshwater and light saltwater applications.

## **Key Factors When Choosing Fly Line Backing**
### **1. Material: Dacron (Polyester) vs. Gel-Spun Polyethylene (GSP)**
– **Dacron (Dac Back)** – The most common choice, Dacron is affordable, abrasion-resistant, and has low stretch, making it reliable for most fishing scenarios.
– **Gel-Spun Polyethylene (GSP)** – Stronger and thinner than Dacron but more expensive. Best for saltwater or when maximum line capacity is needed.
For most anglers, **30lb Dacron backing** is the perfect balance of strength, affordability, and performance.
### **2. Breaking Strength (30lb Test)**
– A **30lb test** is strong enough for most freshwater species (trout, bass, pike) and smaller saltwater fish.
– If targeting larger saltwater species (tarpon, tuna), consider upgrading to **50lb+**.
### **3. Length (100 Yards / 30.3 Metres)**
– A **100-yard spool** is standard for most fly reels, providing enough reserve for long runs.
– For bigger game fish, some anglers opt for **150-200 yards**.
### **4. Diameter & Line Capacity**
– Thinner backing allows more line on the reel but may sacrifice abrasion resistance.
– **Dacron 30lb** offers a good middle ground—durable without taking up excessive space.
### **5. Color & Visibility**
– Bright colors (yellow, orange) help track line movement when a fish runs.
– Some anglers prefer muted tones for stealth in clear water.

## **How to Spool Backing Onto Your Fly Reel**
1. **Secure the Backing** – Tie an arbor knot to the reel spool.
2. **Wind Evenly** – Use a line winder or have a partner hold the spool to prevent twists.
