I've used McCoy Line, for the most part, for many years. I try others, but just keep coming back. McCoy Mean Green is super strong, and HIGHLY abrasion resistant. It casts forever, and has virtually no memory.
I've never cared for fluorocarbons, but McCoy Fluoro100 is the exception. Fantastic line. Made in the USA.
I have used all sorts of fluro line in my years of fishing. I was recently given some to try out from Lyle of southwest customs. I will be spooling all my reels with the mean green fluro! The line has superb sensitivity an I can feel even the smallest of bumps on my line! I will be recommending this line to all my fishing buddies. Great line McCoy!
