Sunline FC Lake Biwa Guide Special was designed specifically for catching big mama bass on spinning tackle.  Sunline FC Guide Special is super soft, super strong, special fluorocarbon line designed by guides on Lake Biwa, one of the foremost lakes for big bass in Japan.  Lake Biwa Guide Special goes to the limit in eliminating shock, which used to be the weak point of fluorocarbon lines, while retaining the same level of abrasion resistance and high specific gravity.
