Hi
By deep what do you mean? 70 or 150m? You have mentioned some very different species there, 30lb (15kg) will knock over any snapper, but sharks etc are a different proposition. However in saying that I pulled up a 6' bronzie from 45m a couple of weeks ago on 30lb
TLD25 with a 15-24kg live fibre on 50~80lb braid for my money.
Little bit more info could open up other rigs.
Cheers
Bill
