OPST's Lazar Line epitomizes everything people love about monofilament running lines: slickness, easy shooting, and thinness. Even better, it lacks memory, the main drawback common in mono. If you like to make a cast and then kick back and enjoy the scenery while your running line is streaming out, maybe taking a bite of your sandwich as you achieve more distance than ever before, Lazar Line is for you. A new spool will have a bit of memory, but if you stretch the line and, even better, pull it through your fingers, you will see that memory disappear. Lazar Line is a low-stretch monofilament, and thanks to that and to its thin diameter, it ties neat and strong knots. We have rigorously tested it in both hot and cold conditions and have found it outstanding at any temperature. In cold conditions, initial line stretching is helpful, but not always necessary as the line stretches some as you fish.
There is more flexibility in choosing a Lazar Line size than with other parts of the system. We typically like 30-35lb on lighter rods: like single hand, trout spey, and Micro Skagit. We tend to go with 40-50lb for larger Spey and Skagit rods. In general, the thinner the running line, the less traction it will place on your guides. Therefore increasing shoot-ability.
