The Helios 3F 6-Weight, 9-Foot Fly Rod is an excellent choice for carp or small stream streamer fishing when roll casting comes into play. The 906-4 is a great rod for quick, precise casts to smallmouth bass and crappie. This is an excellent all around rod for the angler who likes variety and needs an accurate rod to deliver the fly in tight windows. 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.
