TwistLOCK Light with Centering-Pin Spring (CPS-patent pending) is a lighter version of our TwistLOCK bass hook. With guidance from bass fishing professional and lure designer Gary Yamamoto, the TwistLOCK Light was created as the ideal hook for rigging Senko-style baits and other thinner profile plastics. With Owner's unique "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 so that any bait will rig perfectly everytime! The "Open" gap allows for more positive hook sets.
