Trout Tips: Does fly line color matter?

Editor's note: The following is exerpted from TU's book, "Trout Tips," which is available online for overnight delivery.

Some people think it's best to have a fly line you can see, so a yellow or orange line is a great thing. You can better watch your loops form as you cast, and then mend the line effectively as you fish. Great. 

Other say that trout will sense a bright line, even as it is being cast overhead. Remember, the cone of vision for a trout extends up... and out ... and even a bit beyond them, since their eyes are not forward-facing, like human eyes. 

So what's it going to be? Better line control or stealth? The best answer is probably both. Go with as dull or natural of a colored line that you can see, because trout do see fly lines, and they do spook on bright ones. 

But they also spook on bad casts and bad drifts.
