The 100% fluorocarbon fishing line with the highest breaking strain that has yet been tested by the EFTTA. With productiontuned knot strength as well as many other advantages such as high resistance to abrasion, high density, sensitivity, high feed-back, castability (tippet), durability, and low visibility, the STROFT FC1 is ideal for all angling-leader needs. It can also be used as a main line, regrettably at a price.
