I usually cast when i am targetting big sharks and i have never really tried just dropping it down for them so i dont know. I usually take three rods with me when i go. I use my smaller one for kahawai and yellow eyed mullet, then i have my two 12ft rods that i use for bigger fish. And alot of people do overhead cast at night when there is no tourists or other people coming out. If you are targeting sharks at this time of year there are not as many around now compared to in summer. I havnt fished there for a couple weeks now but last time i was there i heard a couple red cod were being caught so the number of them being caught will just increase.
