As the name implies, we designed it initially for tournament fishing, as standard old Big Game, Suffix and even Ande failed us too many times. Perfectly fine lines, until you get them near wire, then they suck. We fish the Great Lakes, and we have thousands of feet of downrigger cable, wire divers, and copper line deployed at any time. You need a tough abrasion resistant mono in those conditions. Our Tournament Mono is infused with abrasion resistant resins and coated with fluorocarbon for even more abrasion resistance.
