Overview
Piscifun's fly line backing is an 8-strand braided polyester line built to sit between your fly reel and fly line, adding reel capacity and cushioning for long runs. It's offered in 20lb and 30lb test with several high-visibility color options.
The braid construction is designed to resist abrasion and stay smooth against rod guides, with minimal stretch to keep it sensitive when a fish is peeling line. Choosing between the two line weights comes down to species: 20lb suits trout and bass, while 30lb is built for salmon, pike and other larger or saltwater fish.
- 8-strand hollow braided polyester
- 20lb and 30lb test options
- Low-stretch, abrasion-resistant construction
- Multiple high-visibility colors
Who it's for
Fits fly anglers spooling up a reel who need backing to fill capacity and cushion a long, hard run. Freshwater anglers chasing trout and bass will want the lighter 20lb option; those after salmon, pike or saltwater species should look at 30lb.
Strengths and trade-offs
Drawn from this product's published specifications.
- Low stretch keeps feel direct during a run
- Smooth braid reduces guide friction
- Two test weights to match freshwater or larger species
- High-visibility color options
- No published reviews yet to confirm long-term wear
- Choosing the wrong test weight for your target species could undersize the line
Performance notes
The 8-strand hollow braid is what gives the line its low stretch and smooth finish, keeping friction down as it runs through the rod guides during a fast take. Because it holds its round profile under the coating, it packs consistently on the reel arbor rather than flattening out over time.
