Rolling swivels have a cylindrical central body, and the obvious difference is that if you look at how the swivel eyes are formed, both swaged tag ends that form the eyes enter, and are secure, well inside the ends of the swivel's body. This dramatically increases the overall strength of the swivel. It also allows the swivel to be reduced a little in overall size.
The Rolling Swivel is also more efficient at rotation when under heavy pressure helping to reduce line twist and tangles. This increase in quality sees a higher retail cost but is a price worth paying.
The sizing of these swivels are normally more consistent, also the strength ratings are more accurate with a size 6 Rolling Swivel being rated as having a breaking point around 40lbs, and a size 1/0 in the region of 100lbs.
Being stronger and more reliable when it comes to pressured rotation, the Rolling Swivel is a popular and reliable choice both for attaching hook lengths, but also as a main connector swivel between a shock leader and the rig when casting under power to long-range with heavy lead weights.
Again, these swivels are available in a nickel or black finish. The black is preferred as the black naturally blends in better with any surrounding ground the rig is fishing on.
