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 centre of the nose of a soft plastic, which can then be screwed onto the TwistLOCK coil spring to rig perfect everytime! 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 (as opposed to rolling or flipping where weights are inserted inside soft baits). Ideal for both fresh and saltwater fishing.
