Destin help

[longcast]

I need some help. I do not know **** about offshore fishing. The ? I have is about trolling for kings. I ran a rig with live bait I caught at the pass and a artificial bait I had luck on last year. 2 hook up and I lost both fish. Dang it. First fish hit live bait and turned out to be a 5-6 lb shark I lost at boat due to it became unbuttoned.pissed. I have video. Second strike was artificial and was lost due to drag to tight.can someone tell me a little about trolling. Thanks. Rookie mistake.
