# **How to Choose Scientific Anglers Dacron Fly Line Backing: 20lb & 30lb, 100-5000 YD**
As an angler, selecting the right backing for your fly line is crucial for maximizing performance and durability. **Scientific Anglers Dacron Fly Line Backing** is a top-tier choice for anglers who demand strength, reliability, and smooth casting. Whether you’re targeting large saltwater species or freshwater giants, choosing the right pound test (20lb or 30lb) and length (100 to 5000 yards) can make all the difference.
In this guide, we’ll break down the key factors to consider when selecting **Scientific Anglers Dacron Backing**, ensuring you make the best choice for your fishing needs.

## **Understanding Dacron Backing: Why It Matters**
Backing serves two primary purposes:
1. **Provides Extra Line Capacity** – When a strong fish makes a long run, your fly line alone may not be enough. Backing ensures you have sufficient line to prevent break-offs.
2. **Protects Your Fly Line** – By filling the reel spool, backing prevents the fly line from coiling too tightly, reducing memory and improving casting performance.
**Scientific Anglers Dacron Backing** is made from high-quality polyester (Dacron), known for its strength, abrasion resistance, and minimal stretch. Unlike cheaper alternatives, it won’t degrade quickly under UV exposure or saltwater conditions.

## **Choosing the Right Pound Test: 20lb vs. 30lb**
The strength of your backing depends on the species you’re targeting and the drag settings of your reel.
### **20lb Dacron Backing – Best For:**
– **Medium-sized freshwater fish** (trout, bass, pike)
– **Light saltwater species** (bonefish, redfish)
– **Smaller reels** where thinner diameter is preferred
### **30lb Dacron Backing – Best For:**
– **Large freshwater & saltwater species** (salmon, steelhead, tarpon, permit)
– **Heavy-duty setups** where extra abrasion resistance is needed
– **Big-game fishing** where long, powerful runs are expected
**Pro Tip:** If you’re unsure, **30lb is the safer choice** for most saltwater and big-fish applications.

## **Selecting the Correct Length (100YD to 5000YD)**
The amount of backing you need depends on your reel size and fly line weight. Here’s a quick reference:
| **Reel Size (Fly Line Weight)** | **Recommended Backing Length** |
|——————————–|——————————-|
| Small (3-5wt) | 50-150 YD (20lb) |
| Medium (6-8wt) | 150-250 YD (20lb or 30lb) |
| Large (9-12wt) | 300-500 YD (30lb) |
| Extra Large (12wt+) | 500-1000+ YD (30lb) |
| Big Game / Offshore | 3000-5000 YD (30lb) |
**Key Considerations:**
– **Saltwater anglers** often need more backing (300-1000+ YD) due to long runs from species like tarpon and tuna.
– **Freshwater anglers** targeting trout or bass may only need 100-250 YD.
– **Offshore & big-game anglers** should opt for **3000-5000 YD spools** for heavy-duty applications.
