Although I've never tried McCoy products, I hear a lot of positive comments about their products.  They manufacture a co-polymer, braid, and Fluorocarbon.

Has anyone here tried their products? How do you think they stack up to competitive brands for endurance, performance, and price?

Ive never had a bad experience with their co-poly.  Their fluoro is very very stiff though.

John Tanner turned me on to McCoys line about 5 years ago and I have been using it since. I use mostly the 15lb Co-Polymer and I use the 65lb and 20lb braid. I have used other lines and braids every now and then just to check them out and always go back to McCoys. I really like the co-polymer especially in cold weather because it doesn't curl up and stays really flexible. It is also a really tough line.  I really like the softness of the braided lines, they move real smooth through the line guides. I usually put new braid on at the begining of the year and use it until the next year.
