Choice of hooks is a personal thing. For my baitfishing it’s either a size 2/0 or 4/0 wide-gape J hook, or long-shanked worm hook. I don’t get on with circles, except for ray fishing.
I match the hook size to the bait and, as this is predominantly either whole squid or black lugworms tipped with squid, the sizes mentioned suit me the best.
One thing I have been doing of late, after noticing that bites tail off once the ring of squid has been stolen, has been to leave a tag end of a centimetre or two as a baitholder. I leave the worm above that, with the hookpoint clear and the ring of squid easily taken.
Almost all of my species hunting and drift fishing is done with pre-tied feather, hokkai and sabiki rigs, and these range through size 8, 12 and 16, with larger size 2/0 feathers where I might reasonably expect to be hitting shoals of mackerel and bass. Wedges or jigs provide the weight, giving two bites of the cherry.
As always, the key is in experimentation to suit local conditions.
Experiment with hooks to find what suits you
