The #4X102Z is the flagship of the RonZ® line. This size and series is a favorite for targeting large tuna and other big game species. With a casting weight of 4 oz. it will go the distance needed, even when cast with heavy braid and leader. The rate at which this bait sinks makes for ideal action and speed on the drop. On Spinning gear this bait can be dropped to 200ft with little effort. Fish find this sinking action irresistible. Picking up where the 3X Series leaves off, the 4X102 is Ideally suited for Larger Tuna and other large game fish over the 100lb mark.
