Frequently Asked Questions (FAQs)
1. What is the strongest fishing line material?
Modern synthetic fiber-based braided line is the strongest fishing line on the market, and over 10 times stronger than steel, which brings along its own benefits and limitations. Because it's thinner, you can fit way more of it on a spool, enabling use with much smaller spools and reels than with other lines.
2. What is the strongest thinnest fishing line?
Braid. Braid is very strong for its diameter, and it has virtually no stretch. Because it's the thinnest of the line types (by breaking strength) and very soft, it casts well. Because it's the most opaque and visible of the line types, many anglers choose mono or fluoro in clear water.
3. Which brand of fishing line is the strongest?
You'll most likely have to cut the line and probably lose your lure if either of these gets stuck. When it came to strength, the SpiderWire Stealth Blue Camo-Braid was the clear winner. It was by far the toughest line we tested, proving to have great abrasion resistance and fighting power.
