My hook size for general fishing is 10/0 although I’ll use 5/0 for rig and elephant fish and been using 1/0 circle hooks for kahawai etc Had some cheap 7/0 hooks off trademe that bent really easily and PierMaster had a 5/0 bend out on a big skate at kaikoura. Also had a 10/0 bend at the kaikoura wharf but I’m pretty sure that was from pulling the stingray up the stairs with the gaff. Sabiki hooks and small trout hooks don’t take much to bend I’m still looking for some small size 10 or 12 trout hooks that wont bend so easily. I think I read somewhere about a guy fighting an eagle ray on 6kg for something like 6 hours.
