I was looking into this also for price and handling reasons. Co Poly will be very abrasion resistant, sometimes even more than fluorocarbon, but it will not be as sensitive. At many times it will have better handling. There are some good inexpensive Fluorocarbon lines, Seagaur makes really good lines, and they are inexpensive and they are all on sale on Tackle Warehouse for the 25 Days of Christmas sale. Red Label is very inexpensive, there are mixed opinions on it. Invizx is also fairly inexpensive, not so much as Red Label, but it has better opinions in terms of use as a mainline. It is soft and supple, which is why it's a good option if you are worried about handling (I also like Berkley Trilene Professional Grade 100% Fluorocarbon XL if you are worried about handling, but it cost slightly more). Abrazx is also on sale, and is stiffer than Invizx, but it is also more sensitive and abrasion resistant. There are plenty of quality choices that are fairly economical when it comes to fluorocarbon line.
