Since the breaklines and structure are the actual migration routes of the fish, and Breaks offer "cover" and location identification for the fish, we must present the lure or bait directly over the Breaks and Breaklines on structure. If the Breakline is located 20ft. deep, we present the lure at 18 to 20ft. deep. When the fish are neutral or dormant, we present the lure or bait over their sanctuary in deep water. Trolling at the proper depth and speed is the fastest way to find the productive Breaks and Breaklines.
