I have run lead core from Buffalo to the Ohio Islands, lead core is a huge part of my program. I will run 3-5 colors in the shallower waters of the western basin and 3-10 colors around my home waters in Ny State depending on how deep we are fishing. Don't ever discount lead core as an old school technique, I will run lead core over dipsys any day. I'm a Prostaffer for Torpedo Divers and have eliminated my dipsy program using the Torpedo Divers, they are so much easier to use.
