This "Uber" is not just a shad tail worm. It is a worm that has been created with various attention to detail.
The body is a streamlined shape reminiscent of a baitfish, with indentations on both sides.
The indentations allow the lure to catch the water current, suppress unintentional swinging action of the body, and stabilize the swimming posture.
The ribs installed only on the lower half of the tail are designed to fit securely into the mouth of a predator when it inhales it. The ribs reduce the water flow that the tail receives, allowing only the fluttering tail to appeal and lure the predator into predatory mode.
