Opti-Mex rigs are pre-tied using the highest quality 100% Fluorocarbon Opti-mex hooklink. The light refractive properties of fluorocarbon are very similar identical to that of water making them almost invisible. Excellent anti-tangle properties, they feature a slightly in-turned hook point design, ideal for fishing over gravel and particularly well suited to bottom baits or snowman style set ups.
