The fishing line that an angler puts on a reel can make a big difference in how much fishing success that angler will experience. It is recommended that every new fishing season be started with new line. That's why many tackle shops have line-spooling specials this time of year.
Line is measured in diameter and line-breaking strengths.
The larger the diameter, usually the higher the break-strength. There are several things to keep in mind when you're determining what line to buy. One of the first considerations is the size of the bait you will be using. If you're going to be throwing small jigs, you will want to go with a lighter line. Light line handles small lures much better.
