Orvis Helios 3 Fly Rod
3F is accuracy with finesse, a dry fly angler's dream. 3D is accuracy with power at distance for pinpoint delivery of larger flies. The difference is taper and stiffness, but the design foundation of accuracy remains constant
These rods are amazing! The technology packed into them really does make a difference in tracking and line control. Usually we are critical of the marketing blather, but the Helios 3 rods really live up to their claims of accuracy.
