The Intelligent Backlead by Korda is one of the best and safest top lead systems ever designed. This top lead is very easy to attach and detach to the main line. By pressing the eye of the top lead into the rubber, you prevent the top lead from falling off the line during the retrieve. Should it happen that the top lead gets stuck in an obstacle during the retrieve, the top lead can easily be released from the rubber. The eye of the top lead is made of a very smooth material, so the system slides easily over the main line. Of course, this top lead also ensures that your main line lies tight over the bottom.
