Phenix Axis Conventional Rods are built with the latest materials and design for the strongest, lightest rods available. Our composite blends of S-Glass and T-16 carbon fiber offer powerful strength-to-weight ratios, while multi-helix construction makes our rods perfect for saltwater. With thin diameters and light materials, Phenix Axis Conventional Rods offer superior strength, responsiveness, and castability. The 7&';2" 2X Heavy and 3X Heavy are considered rail rods with a longer foregrip. You may ask yourself "Why would I want a rod that long and that heavy?" The longer rod is necessary for a rail rod because so much of the rod is fore grip. When the fore grip is put on the rail, you may have only 4-5 feet of the rod actually fighting the fish. The more rod you have outside the rail, on the water side of the rail, the more the fish has to fight. This makes it much easier for the angler to fight the fish because the fulcrum is now the rail and not your arms. All Rods are packaged with extreme care! Rods over 8&'; do not qualify for free shipping. Being fisherman ourselves we take pride in not having rods break during shipping, to ensure they&';ll be enjoyed and fished. We make sure every rod is wrapped tightly with bubble wrap in the crucial areas and are suspended in a thick rod tube, to keep from being crushed or banged around.
