Have you ever used a hooklink that knew not to tangle? One which the fish could hardly see and one that made it more difficult than any other to eject? Open this packet and maybe for the very first time you will be.
IQ is fluorocarbon which refracts light in almost the same way as water making it almost invisible when immersed. It is stiffer than normal nylon so improving anti-tangle and anti-eject properties and now it's available in a super soft version.
