I was fishing with 6lb Nitlon leader recently and catching Whiting, Bream, Flathead, School Jew etc on Bloodworm Squidgy Wrigglers when I hooked a reasonably big Flathead (70 cm +) and lost it when it sawed through the leader at the boat with a single head shake before I could get the net under it. It had completely inhaled the Wriggler so my leader was running over the rasping bottom jaw.
Although I prefer to fish as light as possible I resent losing decent fish so decided I had better buy some more 12lb Nitlon Fluorocarbon Leader (I’ve nearly run out) but before I did I thought that I would conduct some tests to compare the abrasion resistance of the lines that I currently use for leader.
I dragged some 12lb Berkley Vanish, 12lb Nitlon and 15lb Black Magic Tough Fluorocarbon Leader from side to side (to simulate a big Flathead shaking its head) over the 90 degree rough edge of my bench vice jaw and found that although there wasn’t much difference between all three lines the 12lb Vanish was harder to break and scuffed up quite a bit before it actually let go.
I have always suspected clever marketing and popular perception allows fishing line manufacturers to charge a premium for “leader” material that is no better (if not worse) than plain old Berkley Vanish which sells for less than a quarter of the price.
How ‘bout that.
