Seaguar Pink Label 100% fluorocarbon leader material is made from exclusive Seaguar resins. Pink Label is soft and supple with superior strength, abrasion resistance and minimal stretch. It's also lightweight and buoyant, so it can cast farther and perform better underwater than other fluorocarbon lines. The pink color is one of the first colors to disappear in water making it even more invisible than other colored or non colored lines. We have had bites where they would only bite pink label, it's worth a try if you haven't already.
