Drennan E-Sox DropShot Fluorocarbon Leader, E-Sox Dropshot Fluorocarbon makes an ideal leader material. It is supple enough to ensure a lure behaves naturally, yet stiff enough to avoid tangles. As it is made from 100% fluorocarbon it has a very similar refractive index to water, making it almost invisible and therefore much harder for a fish to detect. Dropshot Fluorocarbon Leader has exceptional abrasion resistance and high knot strength for its given diameter. It also works well with braided reel lines. Four breaking strains are available, each on handy 50m spools.
