Why not just Incorporate the lures in to the wires them selves. Have the hooks actually be part of the bait and not an attachment that can be swapped. Whether someone just twists 5 hooks on 5 lines or pour 5 resin baits on 5 lines or what. With the connections being terminal then with my reasoning it should be one bait and not 5 attached with swivels. One bait 5 hooks still less than most crank baits.
