Orvis set out on an adventure to make the world's lightest fly rod. Along the way, they also made the world's best. The new Helios 4 weight is so innovative and, frankly, so far ahead of all other fly rods it skips generations in how fly rods should feel, cast, and fish. This 4 weight is so sublimely light, incredibly responsive, deadly accurate, and just plain easy and enjoyable to cast that to compare it to other graphite rods is like comparing graphite to bamboo. There is no comparison. The 4 weight Helios rods are that good, and everyone is noticing.
