i prefer a tuna circle hook with two short lengths of wire,one for the swivel and the other to a treble stinger for trolling livies. i hook the bait through the nose with the circle hook,it is hard for them to get off and they troll straight and when a spaniard swollows the lot the circle hook lodges in the corner of it's jaw bone with the treble usually in it's throat and the short trace usually stops his mates chopping at the swivel
