OK here is a little bit about the lines and what they are made of.
Polyamide (nylon) is the most common.
Co-polymer refers to the merging of two monomer molecules to form a larger copolymer molecule. This process is known as polymerisation. The exact details of such a process are often proprietry and are not available in the public domain. The main thing to remember is that such lines are thinner for the same strength than nylon. They are also more abrasion and shock resistant.
Fluorocarbon refers to lines made from PVDF (polyvinylidene fluoride). These lines are heavier than nylon and copolymer and also have a refractive index close to that of water. That means that when immersed in water, fluorocarbon lines are less visible.
There are many different fluorocarbon lines on the market, some of the cheaper ones having poor knot strength and a tendency to retain memory.
Be careful with your knots when using fluorocarbon. It doesn't like knots that have lots of "bends" in the knot's structure such as grinners or uni knots. A simple 4 turn half blood knot is best for attatching a fly. A two turn water knot, many have found to be the best way of joining fluorocarbon or forming droppers. Always apply spit when tightening these knots.
Fluorocarbon lines do not biodegrade by the way. They will stay as they are - unless burned - for thousands of years. It's best to carry a small rubbish bag, making sure all offcuts of fluorocarbon go in there.
