Power Pro begins with ultra-strong braided Spectra Fiber, which is treated to create an incredibly round, smooth and sensitive line. Green Power Pro is the ideal color for water types ranging from glacial and high run off river systems to all oceanic regions of the World. Green is also well suited for fishing in clear lakes to lakes that have large algae blooms. Because green is similar to many bio organisms, it blends well with the background of the typical surroundings with which a fish is familiar. Power Pro has amazing strength to size ratio.
