How to deal with cracked fly lines

I have tried many of the best fly lines and wonder if they are worth the cost. All have failed me. After a short use, a series of round cracks develops in the whole front end of the line. Is it something I am doing wrong? Perhaps I have matched the wrong line to my rod. I need help.

Q I have been wondering if the modern fly lines are worth the cost. I have tried Air-Flo, Rio, Scientific Anglers and Cortland. All of them have failed me. My problem is that after a short use, a series of round cracks develops in the whole front end of the line. Is it something I am doing wrong? Perhaps I have matched the wrong line to my rod.

There is nothing wrong with any of the lines you have mentioned. All modern fly lines are excellent and will perform according to the manufacturer's specifications. In this case the problem is your casting. Probably all your trouble comes from an improper forward cast.

When we cast a fly we unroll the line; we really don't cast it the way we do a jig or lure with spinning or plug tackle. Just before the line unrolls behind you, you should come forward. You don't want to wait until the line straightens, as that will develop some slack that has to be removed. But in your case, I am sure you are coming forward too soon. In effect, you are cracking the whip. This sudden and violent unrolling of the line causes the outer coating to separate, forming ring cracks.

Try delaying your cast just a little and I am sure you'll find that all of the fly lines you mentioned are fine.
