They are obviously really easy to use but one problem I\'ve found is that when you set say a 1 hook flapper for rock fishing, and the hook gets caught on rock,kelp etc the bottom snood swivel crimp can be dragged down toward the lead as you pull out of the snag. The crimp won\'t slide back into position and can damage the line. To get around this I\'ve started using 2 crimps below the swivel, and although it does improve things it still doesn\'t prevent it happening all the time.
