Helios 3F 4-Weight, 10' Fly Rods offer enhanced accuracy and feel at mid-range distances. When line control and mending are important, you want to fish a light line, and you need the accuracy to toss a streamer up and across to a far bank, the Helios 3F 104-4 is an exceptional choice with the length you need for mending and drift control, and the 3F feel and responsiveness to allow you to detect subtle takes. Whether you're swinging flies in the current or nymphing the run at your feet, this rod offers a big advantage over shorter fly rods. No cast ever thrown is identical to any other cast ever thrown. The variables of caster, rod, and conditions are too great. Helios 3F was designed to significantly reduce the variables at the point of release, focusing the energy of the cast to the intended target. No matter what happens behind you, the energy of the forward cast is crisply released through a tight window created by the most significant reduction in horizontal and vertical tip frequency ever conceived. It is a rifle in a world of muskets and it autocorrects the variables of the cast to the target with incomparable precision.
