Mahmoud,
As Brandon mentioned, they love to bite off expensive lures!
Most people here on this site will call king mackerel a by-catch of GT fishing, since, most do not want the mackerel in the first place!
The spanish mackerel we get in Australia are almost identical to king mackerel and they certainly love stick baits. I'd use slightly smaller stick baits purely to get a better hook coverage. Big mackerel love big stick baits though they can chomp large areas of wood or plastic without hooking up, so slightly smaller stick baits (with some piano wire rigged in front of the lure to prevent bite-offs) would be a start.
I find the mackerel like areas of large bombies and reefs that disturb the current flow. Also cast around shoals of bait. We do get fusiliers here and when they are around, the mackerel, plus everything else, love to eat them!
Aaron.
