I use 60g white Sea Rock metals re-rigged with a single assist off the head, back treble removed. Cast with 305 Daiwa Seajigger rod and 3500 Daiwa Seagate highspeed reel. Got big sambos, countless bonnies but yet to snare a kingy....
Have also experimented with my bigger casting rig 8'3" Zenaq Fokeeto Trevally (PE6-8), Stella 10000 and 65lb braid using Maria 110g metal jigs re-rigged with an assist hook off the nose. No results as yet, not from lack of trying.
Casting around Sydney northern beaches ledges.
