Frequently Asked Questions
The Palomar knot consistently tests at 95–100% of line strength on mono, fluorocarbon, and braid — making it the strongest all-around knot. The FG knot achieves 95–100% specifically for connecting braid to a fluorocarbon or mono leader. For leader connections, the Alberto knot is nearly as strong and easier to tie.
Always use the Palomar with braid. The Improved Clinch knot tests at only 50–65% efficiency with braid because braid does not compress like monofilament. The Palomar (and Uni knot) work much better with braid's slick, non-compressible surface.
The FG Knot is the gold standard — it tests at 95–100% and has a thin, smooth profile that passes easily through rod guides. The Alberto Knot is a good alternative at 90–95% efficiency and is easier to tie. The Double Uni Knot is the easiest option at 80–85% and is reliable for most fishing applications.
Friction heat generated when cinching a dry knot can weaken the line by 10–20%. Monofilament and fluorocarbon are especially vulnerable. Always wet the knot with saliva or water before pulling it tight. This reduces friction, allows the coils to seat properly, and preserves the line's rated breaking strength.
