Line you're having trouble with doesn’t last on the reel long. If there’s any question about the strength diminishing, it should be replaced. That said, you can keep line on a reel for a long time if that reel has not been used much, and if it hasn’t lost any basic strength due to abuse or exposure. (You can do this if you keep your rods out of the sunlight and in a controlled environment when not being used.) A Unique Molecular Bond One very reliable line is Yo-Zuri Hybrid. I use it both as a primary fishing line, meaning that I fill a reel spool up with it, and I especially use it in various strengths as a leader tied via a Double Line Uni Knot to braided (microfilament) line. It’s a very good main fishing line, and an excellent leader line. A lot of anglers are unfamiliar with this product, and many don’t know that Yo-Zuri, which is well known for high-quality, realistic-looking, hard-bodied surface and diving plugs, also makes fishing line. In fact, they have 100 percent fluorocarbon leader and fishing lines as well as the Hybrid product. As the name suggests, Hybrid is a monofilament resulting from the marriage of nylon and fluorocarbon. According to Yo-Zuri, nylon and fluorocarbon are molecularly bonded during extrusion, which is when these different materials are drawn through an extruder into a single strand during manufacturing. The company claims that Hybrid is the first and only line of this type, and superior to nylon lines that are coated with fluorocarbon, which acts as waterproofing. The Best Characteristics of Both Nylon line absorbs water when it is wet, and its characteristics change from a dry to wet state. Fluorocarbon does not absorb water and its characteristics remain the same. Nylon line has some amount of stretch, and is generally fairly flexible and easily castable. Fluorocarbon, as a rule, is less flexible and more problematic for casting, but its high refractive index means that it is much less visible in the water. Merging the two materials into Hybrid has produced an eminently castable line (especially good on baitcasting reels) with low visibility, low stretch (which translates into good sensitivity), and very good abrasion resistance. In my experience, it has also been a very durable line that lasts a long time if cared for properly. The line floats, so it also works well with surface and floating/diving lures, which is sometimes not the case with a pure fluorocarbon product. Actual Strength Is Greater Than Labeled Yo-Zuri Hybrid is made in 4- through 40-pound-test in three colors: low-vis (clear), smoke, and camo-green. I’ve mainly used smoke, which looks translucent gray, but also fished with the green line. Yo-Zuri also makes Hybrid Ultra Soft line, intended for use with spinning tackle, which I have not used. One note of caution is that Hybrid breaks at a much higher strength than what the label says. The 4-pound product, for example, breaks at 8.5 pounds (!), 10 breaks at 16.5, and 20 breaks at 26; these numbers were determined through independent testing by the International Game Fish Association. I take actual breaking strength into consideration when deciding what to use as a main line or as a leader. Eight-, 15-, and 20-pound-test have been my primary choices. I use 8- or 12-pound-test as a leader on spinning tackle equipped with 10-pound-test braided line.
