Can you tell me the advantage of using lead core? I've never used it but from what I can see is that you need to get the harness / spoon / plug down to a certain dept. You can do that by using a Torpedo Diver, Jet Diver, Dipsey Diver, Down Rigger or straight in line lead weight. To me the Lead Core Line is thicker than mono, fireline or wire. It would seem to me that it could spook the fish??? Fishkiller how many poles do you have on your boat?
