What pound test line do you use?
Why Go Light?
Technique over Technology
You see it comes down to a simple game of physics despite all the marketing that takes place on the subject. Lines are "tested" to uncover their breaking points, or how many pounds of tension they can undergo before snapping. In monofilament line it really comes down to line diameter, the thicker the line the more tension it can endure.
Braided line is definitely stronger but also tends to stretch as well as slip from open reel spools creating nasty knots as pictured above and lesser sensitivity. The perfect line is super thin, strong, and majorly sensitive (walleye and steelhead guys know what I mean). Here comes science.
What About Tension?
Tension is the force applied to any point of a line when both terminal ends are applying force unto the line. The thicker the line the more tension it can withstand without breaking. Even the lightest of line may surprise you in how durable it can be when used correctly. The bigger part of the equation is the rod your using. The "softer" the rod the lighter the line you'll be able to use, and here's why:
As noted by Newton's 3rd law every force is counteracted by an equal and opposite force. The fishing line is pulled by the fish and also equally pulled by the fisherman (in literal terms, the rod) But the secret lies in the bending action of the rod. It's also the reason you keep your tip up while playing the fish.
