This curve will primarily be used in the Gulf of Mexico when bottom fishing next to heavy structure like oil platforms. When fishing, the angler needs to place a tremendous amount of drag on the fish to move it away from the structure quickly. As soon as the angler moves the fish or turns its head, he will then quickly back off the drag to the Strike position at 1/3-1/2 the breaking strength of the line. From here until he lands the fish, he will fight it with a traditional drag range and not go back into the Full position again, unless the fish begins to run back into the structure. This curves allows a very high Full position setting, but quickly backs off to a safe area at the Strike setting so that the angler does not accidentally back off too much drag. Anglers will primarily use 80# test.
