Fellow Fishers, Never used leadcore but have seen several shows where it is used. I have a few questions so please be patient. First is a mono backer used on the reel first and then tie the leadcore to it? How is the leader tied to the leadcore, is a barrel swivel used? and lastly, are you using floating lures or can a diving lure also be used and will the depth of the diving lure be affected? Any help is deeply appreciated. Thanks
