A must-have line for the serious lake angler.  Rio has incorporated proprietary lubricants and XS Technology (new for 2009) into the translucent green running line that make the line incredibily slick.  The head remains completely clear.  With an intermediate sinking rate of 1.5-2.0 inches per second (3.7 cm/s), the line is perfect for fishing subsurface and shallow shore lines - ideal when stealth is required for wary, selective fish.  Made on a low memory supple core with a coldwater coating and welded loop on the front end.
