I understand the difference in characterisitics between mono and flouracarbon but what are the characteristics of copolymer line as compaired to the other two? :-/

Welcome aboard!

Copolymers are a blend of more than one monofilament (nylon) or fluorocarbon component. For example, Yo-Zuri Hybrid is a bonded (not coated) nylon/ fluorocarbon blend. Hybrid Ultra Soft has a higher proportion of nylon which makes it softer (less memory). Copolymers tend to over-test (breaking strength), but are often stiffer (more memory) than single component monofilaments. There always seems to be trade-offs when searching for the magic formula.

p.s. I know you originally placed this post in the Professor's section. To ask him a question, send a personal message (PM) as Glenn describes here:

Roadwarrior, the copolymer lines are touted for their LOW memory as compaired to monos. From this site:  http://www.tackletour.com/reviewsufixdna.html    "The Sufix DNA line casts easily and has a very nice feel to it.  It's extremely smooth and glides off the spool going through the rod guides quickly and with little friction.  What allows the superb castability is due to a few factors.  First the DNA line has low memory, as Copolymer lines are known to have low spool memory because they are generally limp. With a low memory and soft fishing line, casting the distance is not a problem."

I understand a copolymer has characteristics of both mono and flouro, but which sinking characteristic does it have?  Does it sink like flouro, or float like mono?  

For some reason I can't find an answer in all of my searches and I feel this is a pretty important characteristic.
