Interchangeable and made of pure tungsten, our new Dark Matter Balancing Weights are an absolute innovation in the sector: they have been designed to be placed on top of a size 11 swivel and to counterbalance a floating bait rigged on the rig. They are ideal for use in combination with Chod, Hinge Stiff, and Spinner rigs, offering a valid alternative to tungsten paste. Made of pure tungsten, with a much denser consistency compared to other rubber products containing tungsten, they have an incredible size/weight ratio that helps give a cleaner look to the final rig. Dark Matter Balancing Weights can be used to counterbalance most rigs with pop-ups and floating baits, a particularly useful feature since achieving the necessary weight to sink the pop-up with Naked Chod rigs can be difficult. They can be quickly replaced, making them perfect when trying to balance rigs; they do not wear out and are reusable, so they will last forever if not lost. They are available in 5 different weights (from 0.30 g to 0.50 g), and each has a laser-engraved identification number indicating its weight—for example, the 0.30 g weight shows the number 30. A "mixed pack" containing 15 weights (three of each size) is also available, allowing you to try all the weights to find the one that suits your chosen rig. Additional information: Freshwater shrimp are attracted to tungsten, and anglers fishing waters inhabited by this species are aware of this. Dark Matter Balancing Weights are the perfect solution to this problem: shrimp will not be able to remove the weights from the rig. Tip: They fit ALL Korda size 11 swivels. Every effort has been made to control the tolerance of Korda size 11 swivels; however, manual insertion remains difficult. For this reason, we recommend using a Krimp tool to correctly insert the Dark Matter Balancing Weight onto the swivel. Note: They may not be compatible with size 11 swivels from other brands as dimensions may vary. Tungsten is a very rigid material with little flexibility, which makes it incompatible with larger swivels.
