but people st croix fly Saying that spearcasting is as much science as it is art, we’re showing physics in motion with the new PHYSYX SPEY rods. This is a new series of five 4-piece two-handed rods ranging from 12’1” 5-weight to 12’8” 8-weight, each optimized for maximum power, accuracy and pleasure for anglers. The rods are constructed from handcrafted blanks made from St. Croix’s exotic super-high modulus high-strain SCVI carbon and refinished with additional carbon fiber material to produce individual actions with optimal levels of flex, power and strength for each rod model. MITO graphene is applied to the blanks at critical locations to further refine the stiffness and flexibility of the rod for improved strength-to-weight ratio and maximum loop stability. Other proven St. Croix technologies built into the rods include IPC, FRS, ART, SPF and TET, complementing the performance, strength and durability while further refining the smooth actions of the PHYSYX SPEY.
PHYSYX SPEY rods are crafted with premium components to deliver a great experience on the water. Starting off with what fishermen will be treated to with each cast, the front and rear grips are a modified full wells design, crafted in floor-grade cork with durable mixed-cork accents. The reel seat is a custom design that is downlocked with a machined aluminum design that features dual locking nuts. The stripping guides are premium Fuji K-series titanium with Torzite inserts, while the snake guides are durable hard chrome.
