The swivel completes your entire set up and is actually the last connection between you and the carp. Therefore, it just has to be absolutely reliable. These new swivels are the same size as the previous version, but the max pull and the reliability are increased. In addition, the swivels have a non-reflective coating, so they are hardly noticeable underwater. The Size 8 Swivel has round eyes, which makes them stronger than swivels with angular eyes. The swivels fit perfectly in the Inline Leads, Lead Clips, Running Rigs, Shok Beads and Rubbers of Korda.
