THe verdict is that if you are fishing in gin clear water and the fish are line shy (the fish see your leader and stay away) you best put on some fluoro. If the fish are not line shy use mono or braid.
My theory is use what will catch fish. If they run from your line you best have a solution to make the line invisible. If copoly will work then go for it.I have seen fish scoot away from line. Heck I even seen them run from me. While I was wearing a nice white T-Shirt and a white hat on a bright day. So use what you need. Dirty water who cares. If it is clear you might want to have something in your box to throw on.
