A Speed Swivel but with an extra ring in between. This creates extra flexibility between the swivel and the speedclip. As a result, the anti-tangle sleeve (this is also presented on our website), which is slid over the speedclip, lies directly on the bottom.
This ring also provides extra flexibility and turning ability so that the carp is less likely to realize that something is not right with the hookbait. The optimal presentation as far as we are concerned and after all, it is the details that can make the difference.
