Lines in this section have hard surface coatings on them, and they are relatively linpy like mono-filament lines. These lines have improved abrasion resistance, and easiness in handling. Because of the hardness, you may use these lines on bait casting reels. For bait casting reels, please choose JP line # 1.0 or thicker. Too thin line will casuse dig-in and backlash, to break lines in casting. Please tie mono-filament top shot for both more abrasion resistance and shock resistance.
