I think 6/0 is a size better suited to bar fishing. I agree with the rest as far as size is concerned- sizes 2, 1, and 1/0 are my favourites. Octopus style in Owner and Gammies for me, although chums do not need finesse hooks or top-notch gear. Chum gear needs to be strong.
As for the bending out of hooks, here's some thoughts:
1) you could be horsing in the fish. Check your drag. This is common with those who are getting used to braided line.
2) check the wire strength of the hook. Some are fine wire, others 2x and 3x strong. It should be on the package label. I prefer 2x strong, as a hook that is too thick-wired creates more resistance when setting the hook. Think syringe needles; a fine- gauge needle goes in my arm (butt, etc.) easily, but bends once I start jumping around. A heavier-gauge needle is more difficult to penetrate the skin and takes one of those hefty nurses to use (Nurse Helga Bagahammers), but stays straight throughout the battle.
Yeah, it's just like that. Now I feel faint. I'm gonna lie down. I hate needles.
Hope this helps.
