Scientific Anglers Spey Lite Integrated Scandi Fly Line

Designed for light double-handed trout spey and switch rods. With a relatively long front taper for more delicate deliveries, the Scandi Lite is ideal for smaller streams and rivers. Available in grain weights from 150-420 in 30g increments, this two-colored line features a textured, black marker at the end of the head that serves as a visible, and audible, notification on where to begin your cast. From riffling dries for spring steelhead to swinging streamers for trout, the Scandi Lite is Spey on a smaller scale. 

Can be used on single-handed rods as well.
