Incredibly light and strong Improving on the original 2015 series, the Shimano 20 Game Type J Overhead Jigging Rod features Hi-Power X and the patented Spiral X Core carbon construction to reduce weight and increase strength. Spiral X Core is Shimano's most advanced blank technology and is built into the core of the rod using Nano Alloy technology and provides up to two and a half times greater strength and improved flexibility. Spiral Core X A high quality carbon tape is glued into the rod core with a high strength resin which results in increased strength in all directions. Compared to rods without Spiral Core X, the blank is 2.5 times stronger. Hi-Power X In Hi-Power X construction, the blank's outermost layer is diagonally wrapped with carbon tape, which forms an array of "X" shapes. The width of the tape, its winding angle and the part of the rod being wrapped are fine-tuned according to the target fish species. The flexibility shows Shimano to adjust these wraps during construction for precise actions, enhanced overall strength and added twist resistance. In short, Hi-Power X construction delivers sharp and crisp rod control.
