The TRENDEX® Flex-heads are specially used for bottom-jigging, spinnfishing or on a drop shot rig. The softlures move lifelike, very flexible like no other rig. The metal clip inside the lead ball can easily be removed and a flex-head hook (either normal or loaded) can be attached. If necessary the weight can be changed during the fishing. The other end of the metal clip goes to the end of the fishing line.
