I have yet to use these. But, a good old fishermen neighbor of mine gave me some to try. He said he used to kill the fish in the bay with them. And that they are some of the best baits to use. The packs he gave me came with some big heads and he said to spray some WD/40 on them. I believe he said to jig them with a popping cork. He has a lot of info and said a lot of things so I might have mixed some of the techniques up here. I’ll have to have him refresh me before I try.
