The Scientific Anglers XTS Gel Spun Backing – 30lb / 250 yards – Yellow (Product 673120) is a high-performance backing line designed for fly fishing. Here’s a breakdown of its key features:
Key Specifications:
– Material: Gel-spun polyethylene (GSP)
– Breaking Strength: 30-pound test
– Length: 250 yards
– Color: High-visibility yellow
– Diameter: Ultra-thin (thinner than traditional Dacron backing)
– Designed For: Saltwater and big-game fly fishing
Advantages:
1. Strength & Thin Diameter:
– Gel-spun fibers provide exceptional strength-to-diameter ratio, allowing more backing capacity on reels compared to Dacron.
– Ideal for large, fast-running fish (e.g., tarpon, tuna, bonefish).
2. No Stretch:
– Minimal stretch improves sensitivity and hook-setting power.
3. Knot Strength:
– Holds knots securely (use a Bimini Twist or Albright knot for connections).
4. Abrasion Resistance:
– Durable against rough fights and reef/rock encounters.
5. High Visibility:
– Yellow color helps track line movement and detect runs.
Compatibility:
– Works with most fly reels, especially large-arbor models for saltwater/big-game setups.
– Pairs well with fly lines needing extra backing capacity (e.g., 10–12 wt setups).
Potential Considerations:
– Slippery Texture: Pre-wetting knots is recommended before tightening.
– Not for All Applications: Overkill for small freshwater fish; better suited for demanding saltwater scenarios.
Alternatives:
– Dacron Backing: Cheaper, more stretch, but bulkier (e.g., SA Standard Dacron).
– Other GSP Brands: RIO Powerflex, Cortland Micron.
Final Verdict:
A top-tier choice for anglers targeting powerful fish where maximizing reel space and strength are critical. Its thin profile and no-stretch design make it a favorite among saltwater fly fishers.
