I knew that would draw some fire. Most of us have tangled a feisty king into a rigger, but most of the time those fish are close to the boat and up high and even can be netted. Run wire back 200 ft and anything can get into it. Of course the same is true with braid, but braid is not apt to cut mono. I'm in no way implying that wire will not take fish. I just wanted to point out the Con. Whatever works best for you.
A few years ago on a different site, guys were switching rigger wire to braid because they said the wire spooked the fish. A short time later the same ones were singing the praise of wire divers. Spooked on the riggers but not on the divers.
