Some guy that knows of a guy who knows a guy that catches halis told me:
Spectra ok
Which flouro or mono, who cares......fisherman choice
He uses circle hooks with increased hook up since he went to them.
Usually fishes a treble stinger
Fishes with reels IN gear. No waiting, if the Hali hit it , it is likely hooked.
No gut hooked fish by letting them "run" with it.
Enjoy and don't over think it. Its just fishing.
