Heavy gear is quite commonly used by livebaiters in the seaway, still doesn’t seem to matter much to the real big fish, though if you hook them away from structure you are in with a chance. I’ve been busted off multiple times on 50lb overhead gear, there some big kings in there, biggest I have seen went 23kg(1.7m). Also big cod, sharks, groper will give you some grief if you hook them. It’ll be interesting to see how you go.
