Description Description Hide Show This all-round leader line features Sunlines signature Triple Resin Processing (TRP) , which fills the microscopic gaps between the molecules to create an ultra-smooth profile. This specialized treatment significantly enhances abrasion resistance against rough structure, teeth, and rocks while improving knot tying slickness . With a high specific gravity of 1.78 , it cuts through the water column quickly and sinks faster than standard monofilament. It maintains a light refractive index very close to water, making it virtually invisible underwater to prevent spooking line-shy fish. It is engineered with low initial elasticity to ensure high sensitivity for detecting subtle bites, while still retaining just enough flexibility to absorb heavy shocks.
