The Amplitude Infinity "Black Box" Edition is our staff's preferred line for the Sage X 590-4. It has an excellent range loading easy at close range for point blank casts, but seems not get clunky when we need to reach out there for long shots with a #16 Caddis and lay the fly down soft. Streamers... no problem.  Double Nymph rigs... no problem. The Infinity is a line that can fish short, long, and everywhere in between. Hence the name.

Sage X - 9' 5 Weight Single Hand Fly Rods 

This is our BEST SELLING primo kick ass 5 weight rod of all time. If you had one rod to rule them all, the Sage X 590-4 would be it. Fast action, yet touchy enough to do all the fishy stuff like mending, feeding, and short roll casts. It's light in hand but yields tremendous power when necessary.

While supplies last, nothing else dollar for dollar can hang with the deal we have on the remaining inventory of 5 weight rods. Red's Fly Shop still has some remaining because of our huge inventory while most other shops are sold out.  


The X rods all-new fast action taper built with our KonneticHD Technology delivers greater blank recovery and a crisper tip stop - creating tighter, more efficient loops throughout all ranges of casting styles. This taper allows you to dig deeper into the rod and access the lower sections, shifting power closer to the angler. Decreased lateral and medial movement and vibrations in the blank result in a more accurate and efficient presentation, resulting in a performance driven, forgiving fast action blank - refining the energy between angler, rod, line, and fly.

Tighter loops. It's what we all strive for. A tight loop is accurate, efficient, easily controlled, and a way to command the water in front of you. Ushering in a new era of performance fast action fly rods, the X will dramatically enhance the way you fish through superior loop control. With our innovative KonneticHD Technology came new inspiration and opportunities in rod design. 

KonneticHD Technology is the next era in performance graphite rods. Optimizing our graphite-to-resin ratio, we have created a higher density (HD) fiber composite, resulting in lighter, stronger blanks which deliver unmatched recovery, energy transfer, and line/loop control. Building upon proprietary construction techniques developed for Konnetic Technology, KonneticHD gives us an elevated platform to achieve new levels in rod design.


KonneticHD creates amplified strength-to-weight and stiffness-to-weight ratios as needed within the rod blank. Optimized fiber-to-fiber energy transfer along the length of the blank minimizes both lateral and medial vibrations, delivering accuracy in an easy loading blank with quick recovery, a crisp tip stop, and enhanced line feel for complete loop control. The highest energy transferring material we have ever created, opening new doors for our R&D Team to experiment with construction techniques, taper designs, and action profiles.
