The Shimano Poison Ultima Casting Rod represents the pinnacle of rod building technology, bringing Shimano's premium JDM offering to the North American market. Advanced blank construction, revolutionary guide and grip systems, and scientifically optimized designs combine to create a rod that delivers unmatched performance for serious tournament anglers. The foundation of the Poison Ultima is the advanced blank construction that blends Spiral-X Core and Hi-Power X technologies. Spiral-X Core wraps the blank in multiple layers of carbon fiber at opposing angles to create incredible multi-directional strength while maintaining an incredibly light weight. Hi-Power X further reinforces the blank with additional layers that dramatically increase twist resistance, ensuring maximum power transfer during hooksets and fights. The result is a blank that feels light and responsive in hand but delivers the backbone and power needed to control big fish. The X-Guide system unlocks the full potential of these advanced blanks by dramatically decreasing overall weight and providing heightened casting performance. The strategically positioned guides reduce blank stress and optimize line flow for longer, more accurate casts with less effort. X Solid Hi-Power tip construction provides exceptional sensitivity and durability in the tip section, allowing you to detect the lightest bites while maintaining the strength to handle aggressive hooksets. The Full Carbon Monocoque grip is a game-changer for sensitivity. Traditional EVA or cork grips dampen vibrations, but the one-piece carbon construction transmits the slightest vibrations directly to your hand-you'll feel bottom composition changes, light taps, and subtle bites that other rods simply can't detect. The grip shapes were developed by scientifically analyzing tournament anglers' movement and holding posture, resulting in ergonomic designs that reduce fatigue and elevate performance during long days on the wa
