What's your location?
Many of us who fish kings use different tactics in different places. However, you can never go wrong with a live runner under a kite or a balloon. If available, ribbon fish are awesome drifted or slow trolled. I also like a live horse ballyhoo drifted at mid-water with a release sinker. And the old reliable white bucktail still produces. Make sure you chum heavy.
Good luck!
