Fishing line is a key component to your fishing rig, and like so many other aspects of fishing, the options are practically endless. If you are new to fishing, the most important thing to know is that fishing line comes with a “pound test” rating. Simply put, the higher the test, the stronger the line. For example, a 4 pound test line would be weaker and more likely to break than an 8 pound or 10 pound line. You will want to choose a fishing line that is strong enough to reel in the fish you intend to catch.
