Ive just started using 3/0 , only cause the store had run out of 2/0 ….
I now use a 3/0 with a 2/0 as sliding keeper , until the last of my old hooks are used up
Ive never had any probs losing fish ….came close when a large conger bent a hook and fell off once beached ……
Just make sure they are sharp …..
Good value for money is K-Mart …50 hooks for $10 ….
