Can you catch BRs with small hooks? Sure. I've caught them on hooks as small as #2 circles. However, as SS just said, they have huge mouths. When I'm targeting them, I use big baits and use big hooks because I use big baits. Like Loy, my normal hook size is 14/0 to 16/0, with 15/0 and 16/0 preferred. I've caught reds on hooks as large as 20/0. All my hooks are in-line circles, not offset. Some fish will still get hooked deep. I use a pair of extra long Harbor Freight needle nose pliers for that. If I can't unhook them with that, I cut the leader. Remember, these are fish that eat crabs, hardheads and other sharp things for a living. A swallowed hook isn't going to bother them.
