Designed with a long head and back taper for precise presentations to spooky bones Front-weighted to quickly load a fly rod for minimum false casting Long head, and back taper for maximum casting versatility Low stretch DirectCore for hard, solid strip sets Built with RIO&';s exceptionally slick, durable SlickCast coating SureFire tricolored measuring system for increased accuracy and distance control Designed With A Long Head And Back Taper For Precise Presentations To Spooky Bones RIO&';s Elite Bonefish line has a long head and back taper to smooth out the loop, and to make long efficient casts, while the mid length front taper produces great turnover and easy presentation of typical bonefish flies. Each line is built on RIO&';s low-memory DirectCore that is extremely easy to anneal (stretch) and lies perfectly straight on the water, yet retains the stiffness needed to cast in hot conditions. In addition, this line is built with SlickCast, creating the slickest, most durable coating on the market-producing the least amount of friction ever measured in a fly line. The Bahamian colorway has its first color change at 30ft. Other lines with Surefire change at 20ft. The core strength of this line is as follows: - WF6 - WF7 = 30lb (13.6kg) - WF8 - WF9 = 45lb (20.4kg)
