JD,
I think the biggest difference between Fishing BM's and Kings is depth. While we pretty much , as DR would say, "Ring the Dinner Bell" for the BM (bounce bottom) it's a different story for the kings. Starting early in the morning you may want to start fishing as shallow as 30 to 60 feet on the downriggers and then as the day gets brighter with sunlight gradually start working down deeper. And while finding bait is always a good thing, I don't think it is as important for Kings as it is for Black mouth. Those BM's are residents and are pretty much always searching for food, the Kings are migrating through and are going to pretty much follow a path to where they are going and will feed as the opportunity arises. Pretty much all your BM tactics should produce kings as well. Herring, Hootchies, Bucktails, Coyote's, Sonic Edge, Silver Horde's whatever.

Good luck out there, they should be coming soon!
