I don't claim to be an expert on this subject but, I would like to offer a suggestion to those that have their line broken by a fish. There are several things that causes this problem. First is that the first 14 or 16 feet of your line is damaged. Second is that a small cat has nicked your shock leader. Third is that your drag is catching. Last is that you have old line. Here is what you can do to avoid all these situations: (1) Each time before you go fishing, remove all the line from the reel opening to the tip. Then retie your new shock leader to the fishing line. (2) Each time you catch a small cat, check your shock leader to be sure that it does not have a nick in it. If it does, replace your shock leader. (3) When you get home from fishing, back your star drag off to where you have no drag, then store your equipment. (4) Replace your line at least once a year. Also, your should put one or two drops of oil in your reel every two or three months and grease your level wind at the same time if you are using a bait caster. Try these suggestions and you will never regret doing so.
