King Rigs
Kingfish or Trolley Rigs are very popular on the OBX piers. The beaches slope very gently down there, and these rigs help present a live bait to it's best advantage.
The Spanish Mackerel and Blues are hard on your baits, and not very sporting on a 30# trolling outfit, but the occasional Kingfish, Cobia or in my case last year, 9' Hammerhead, will get the blood pumping.
I personally think that Maryland and Delaware coastal anglers are missing a real thrill, when they ignore the mighty Cobia.
