Beast Hooks with TwistLOCK Centering-Pin Spring (CPS) are designed for weedless-style rigging of larger plastics like big swimbaits, flukes, tubes and creature baits. With its TwistLOCK Centering-Pin Spring (CPS — patent pending) attached to the hook eye, baits can be permanently secured by inserting the pin in the center of the nose of a soft plastic, which can then be screwed onto the TwistLOCK coil spring to rig perfect every time! Different Size springs are matched to hook size to maximize holding power. Quick-drop shank below eye allows for rigging fat-headed baits and maximum gap allows for improved hook sets because of better bait clearance. The non-movable weight attached (5130W) not only helps to sink or swim a rigged bait down into the strike zone, but because the weight is positioned so low on the shank, it provides a keel effect. As a result, when rigging large swimbaits weedless-style, plastics swim naturally.
