In the days,matter of fact,earlier than Garbo described: We used straight wire,with two single eagle claw 3/0 cadmium coated hooks that we would allow to rust a bit before using.. We would sharpen them up,cause back then we didn't have those fancy presharpened sumbeetches they have today,attaching one hook at the front of dorsal and the other near the anal fin.. That worked WELL when water was super clear.. Then we started attaching mono to the wire with Albright (which isn't the best knot but when attaching to wire without a swivel which would be more hardware for the king to see,it worked,especially since your running line or 50 shock would break before that 80 would).. This rig worked GREAT for kings,we had to upsize a bit when cobia started showing up in numbers off Frisco around 78,but the same general rig..
PS I don't remember but a FEW and I mean a FEW out of hundreds caught with this rig that were foul hooked like a treble would do.. They were hooked in the roof of the mouth or the corner of the jaw.. Which would be a rarity nowadays..
I talked to a friend of mine that I fished with yrs ago using this rig,and he as well as I don't understand the need for all the trebles nowadays..
