I don't know if all the information about fluoro's invisibility is true.

But, I decided a few years ago to try it. I mean, if it's less visible, you can use a heavier tippet size and still catch lots of fish. I fish mainly in a very clear lake, that holds lots of big fish. Less visible and heavier are things that would help me in my fishing.

So, that's what I did. I went to heavier fluorocarbon (from 4# mono to 8# fluoro). Since I switched to fluorocarbon tippet I've caught more fish, had fewer breakoffs, and landed the larger fish faster with less stress on the fish (still killed the biggest one, though, but I'm hoping she was near her end anyway) .

Now, maybe all the hype about fluorocarbon being less visible is untrue. Maybe I could have just used heavier mono and still caught the same fish. That would mean that the concept of tippet visibility is less important than I've (and many others have) always believed.

I like my results, which admittedly are anecdotal, so I'll keep using it.
