Two FRED ARCHER "RUCKUS RAISERS" on each flat line second and fourth wakes back. Fish on the front side of the wake. Then run Seawitch rigged ballyhoo on the short and long riggers. Put you a bird down the center with a Green Machine trailing about 9ft behind. Hold on, cause them "Ruckus Raisers" are gonna bring up.
If they are associated with a buoy or FAD other techniques such as live bait, drop stone, jigging etc may out produce trolling. Tell us more about the size yft you are seeing, your location, productive methods used by other fishermen etc.
