The micro-Spey has its own action for swinging and mending smaller trout streamers and wets. The two shortest trout rods have a slower action designed for short casts as compared to more conventional models. The basic saltwater models have a faster action designed for bigger flies, bigger fish, and windy conditions. The new Clearwaters improved the rod blank materials using a blend of standard, intermediate, and high modulus graphite depending on the rod model. The rods have between 10 and 15% improved strength, depending on the exact rod model. The Clearwater 763-4 is an exceptional small stream rod that provides the delicacy and precision of a higher priced premium rod. When high mountain streams or spring creeks call, the medium action Clearwater 763-4 answers with all the performance, casting pleasure, and feel you would expect from an Orvis designed rod.The new Clearwater Rod Series is not just a cosmetic face-lift, but a complete overhaul from the ground up by our Vermont rod designers. Everything has changed except the value. It's still the best fly rod you can buy for the money, but with a significant upgrade in performance and looks in a comprehensive series that covers every angler from small stream addicts to Skagit slinging two-handers. Each rod was designed with a purpose-built profile and action to handle the kind of fishing the rod model would be traditionally used for, from medium-action small stream rods to medium-fast freshwater rods and fast-action big game rods.
