I use 5/0 octopus hooks. There was actually a study done using different hook sizes for fluke. The study was designed to explore which hooks caught well and helped to minimize the catch of undersized fluke. 5/0 was found to be that size. When you fish with smaller hooks you get more gut hooked fish and more undersized fish. When you get up to 7/0 you start reducing your catch of keeper size fish.
I used to use 4/0 Kahle hooks. They are thought to cause less gut hooking then traditional hooks. I have gotten away from using them because if we do deep hook a fluke, they are harder to safely remove from the fish. With a 5/0 octopus hook I can slip a finger in the gill arch and quickly dislodge the hook without causing undo damage to the fish.
