Here’s a detailed breakdown of Scientific Anglers Dacron Fly Line Backing (30lb, Bulk Spool ~5000 yards):
Key Features:
– Material: High-quality Dacron (polyester), known for durability, low stretch, and resistance to abrasion/UV damage.
– Strength: 30-pound test — suitable for large freshwater/saltwater game fish (e.g., tarpon, salmon, or big trout setups).
– Length: ~5,000 yards (bulk spool) — ample for multiple reels or heavy-duty applications.
– Diameter: ~0.022 inches (typical for 30lb Dacron).
– Color: Usually white or off-white (high visibility for backing management).
Use Cases:
1. Fly Reel Backing: Adds extra line capacity under the fly line to prevent spool exhaustion when fighting strong fish.
2. Shock Absorption: Dacron’s slight stretch helps cushion hard runs.
3. Saltwater/Freshwater: Resists rot and performs well in both environments.
Pros:
✅ Reliable Strength: 30lb rating handles aggressive fish.
✅ Bulk Value: ~5,000 yards is cost-effective for frequent anglers or shops.
✅ Low Memory: Stays supple, reducing tangles.
Cons:
⚠️ Thicker Than Braid: Less backing capacity vs. thinner options (e.g., gel-spun).
⚠️ Minimal Stretch: Less shock absorption than nylon (but more than braid).
Typical Applications:
– Large Arbor Fly Reels: Fills space before attaching fly line.
– Big Game Setup: Paired with 8–12wt fly rods for marlin, tuna, etc.
– Backing for Spey Lines: Covers long-distance casting needs.
Alternatives:
– Gel-Spun (e.g., SpiderWire): Thinner but pricier; higher capacity.
– Nylon Backing: More stretch, but less durable long-term.
Final Notes:
Scientific Anglers’ Dacron is a trusted, no-frills backing for anglers prioritizing strength and longevity. The 5,000-yard bulk spool is ideal for guides or DIY rigging.
