Striking technique for sailfish and marlin
Be sure to set the drag to almost free spool with the clicker on when trolling using natural baits. Be alert for a sudden jerky motion from the rod tip because this will signal that the billfish has struck the bait with its bill and will be coming back to take it. Give a 5 second drop-back for marlin or sailfish when he strikes a natural bait like ballyhoo or flying fish. This will give time for the billfish to seize the bait, turn around and swallow the bait.
When using artificial lures like Kona heads or Zuckers, no drop-back is necessary. Instead you should set the hook immediately before the billfish drops the lure.
