Great White
Mate I use very heavy gear and specifically target them. I only got 2 bites for the morning, the flattie and a gt. I use an 8 to 10kg baitcaster with a daiwa blacksheep and xos Softies.
I did an article on deepwater jigging for big flatties for GO FISHING MAGAZINE, it should be out this month. Have a read its got heaps of detail in it.
Cheers Rod
