What is fishing line made of?
Machman has nailed this. All i will add is my own quick explanations. Firstly mono, this is generally nylon, in on big strand, they can determine its breaking strain by its diameter it produces, different colors are simply due to different dyes added. Co-polymer lines are you’re best option, tough, abrasion resistant and with just the right amount of stretch, they are made up of more than one strand of polymer type plastic, and bonded together, i suggest a quality co-polymer line like sufix, or stren. Then there’s fluorocarbon lines, in theory these should 100% fluorocarbon, but often they aren’t and instead are made of a co-polymer, coated with a fluorocarbon resin (fluorine). Real fluorocarbon burns with a yellow smoky flame, coated burns with a blue flame, like most other co-polymers. http://www.cabelas.com/cabelas/en/templa…
