Helios 3 Fly Rods: How to decide between D and F versions (12 of 15)
The ORVIS Helios 3 fly rods come in two different actions. Product developer Shawn Combs discusses the difference between the two actions and how to decide if your fishing conditions favor using the H3D or H3F versions. The D version favors distance and line speed and the action is faster; the F version is more for precise and more delicate casts at closer ranges. Either action gives you the most accurate fly rod you will ever cast.
