Smoother, tougher, and even more sensitive than previous versions, the new and improved Berkley Fire Line Fused Superline outperforms conventional braided lines in numerous areas. Thanks to the unique 8-carrier thermal fusion process that fuses all 8 strands into one, this new generation of Fireline achieves strength and abrasion resistance 5x greater than that seen on other 8-carrier braids. The smooth and supple nature of the line allows for incredible casting distance, while the low-stretch properties and ultra-thin diameter offer sensitivity that is second to none.
