Scientific Anglers XTS Gel Spun Backing – 50lb ／ 250 yards – Yellow – 673076
The Scientific Anglers XTS Gel Spun Backing (50lb / 250 yards – Yellow – 673076) is a high-performance backing designed for fly fishing. Here’s a breakdown of its key features:
Key Features:
1. Material: Gel-spun polyethylene (GSP) – known for its exceptional strength-to-diameter ratio, low stretch, and abrasion resistance.
2. Strength: Rated for 50-pound test, making it suitable for large saltwater or freshwater species (e.g., tarpon, salmon, musky).
3. Length: 250 yards – provides ample backing capacity for most fly reels, even when targeting powerful fish.
4. Color: Yellow – highly visible for easy monitoring of line payout during runs.
5. Low Diameter: Thinner than traditional Dacron backing, allowing more yardage on the reel without bulk.
6. Knot Strength: Gel-spun fibers hold knots well when tied correctly (recommended knots: Albright, Bimini Twist, or FG Knot).
Best Uses:
– Saltwater Fly Fishing (tarpon, permit, bonefish, etc.)
– Big Game Freshwater (steelhead, salmon, pike)
– Situations requiring long runs where extra line capacity is critical.
Pros vs. Cons:
| Pros | Cons |
|———-|———-|
| High strength for its diameter | Slippery texture requires secure knots |
| Minimal stretch for solid hooksets | Can be harder to handle than Dacron |
| More yardage fits on reels | Not as cushioning as nylon/Dacron |
| Resists water absorption | |
Tips for Use:
– Use a backing-to-fly line loop connection (e.g., braided loop or nail knot) for smooth performance.
– Pre-treat knots with UV resin or superglue to prevent slippage.
– Pair with a quality fly line (e.g., Scientific Anglers Amplitude series for saltwater).
Alternatives:
– Dacron Backing (cheaper, more forgiving, but bulkier).
– Cortland Micron (similar GSP option).
This backing is ideal for anglers needing max strength in minimal space, especially in saltwater or heavy-current scenarios. Would you like recommendations for specific setups (reel/line pairings)?
