These leads come to you straight as pictured. They can be bent into a banana shape if desired - trim and twist the brass end wires to suit yourself and fish them between 2 and 10 feet depth in front of a lure to make it run deeper or in front of a spinner to prevent line twist. Unlike an anti-kink vane these can be put on in a matter of seconds as an afterthought, they don't have to be built into the rig before you start fishing. The simplest ideas are always the best.
