Funny you ask I have one friend who is THE WORST fisherman you've ever seen but according to him he's caught every fish in the sea, using every technique, every bait, all gear, all locations... plenty of massive kingfish.. yft, shark etc etc
So we went fishing at a kingy spot a few wks ago - first time i'd fished for decent fish with him. Don't even ask about the squiding lets just say it wasn't cheap and another bloke has 8 beautiful prong holes in the back of his neck.
anyway, I knew he'd never caught a king.. as luck would have it his line goes off first. my god it was hilarious as 2 of us watched him trying to skull drag it up, panicking on 50buck jarvis walker junk with no rod mvt. No tips were offered. he got busted. Prop about 50cm king. Next day he gets spooled thrice on reels worth i'd say $30 with about 4lb ten yr old line maybe 50m of line and about a kilo of drag. You should see the MONSTERS he nearly caught!!!
Next day he brings a handline as he's buggered all his reels. This fish pulled hard so I go for the gloves but he declines them. I put 1 on anyway and offer to hold the line while he puts a glove on but no, can't do that! Maybe i'm a %%%%%, but I took alot of joy in watching him cut his hands! With the gloves on he did get this fish up and it was a good fish, 88cm.
But personally id have to say catching kings on handlines isn't much fun. Unless you just want to eat em. But make sure you have gloves!
