YGK XBraid Absorber Fluorocarbon Shock Fishing Leader YGK XBraid FC Absorber is a hard, tough fluorocarbon leader with a unique softness to the line through YGKs manufacturing process, resulting in the ultimate fluorocarbon leader. On the outside, surface hardness makes the fluorocarbon tough and abrasion resistant, but the added softness increases its flexibility and knot tying ability. This fluorocarbon has extremely low visibility underwater due to its high refractive index which renders it almost invisible underwater. Also, the density of the fluorocarbon allows for extremely good sensitivity, ensuring you feel everything thats happening down the business end and it sinks, keeping a direct line between you and your lure or bait. YGK XBraid FC Absorber is a great leader when you need high abrasion resistance and toughness, whether that means youre fishing around reefs and rocks or youre up against angry fish, or if you need a near invisible presentation on wary fish. Great knot strength, super strong. Made in Japan.
