RIO Premier Lightline fly lines are designed for slower action light rods especially glass, bamboo and slower "classic" action graphite rods.
RIO Lightline fly lines are available in both weight forward and double taper designs. Everything about the Lightline fly line has a slower action rod in mind. True line size so no "over loading" of classic action rods and a short front taper for perfect load control at short distances.
Fly lines have gotten so specfic these days and the Lightline is really classic line and taper design built with modern slickness and durability. Relax and enjoy slower rods in old school trout fishing situations like classic wet fly fishing and spring creek presentation style fishing.
