Please don’t make the mistake of using cheap low quality swivels. If the swivel fails you won’t just lose the fish, you will lose the lure or rig too. A few quality swivels can cost as much as a bag of cheap ones, but one lure can cost much more. Quality swivels often state their strength on the packet, very helpful when tying a rig
Rolling swivels with round eyes are the most popular swivels used in freshwater fishing. Available in a range of sizes from 2 to 14, with 14 being very small and 2 being big. Size 8 is common in Carp fishing with many rig and feeders using eights. For light ledgering and general silvers fishing, size 12 is a common small size to use.
