Trolling is better for sure.i have seen poeple casting from there boats to the outer break wall.sometimes the browns there will use the outer breakwall to trap a school of baitfish and feed.if your there earlly in spring or water temps are cold i have had better luck with rapalas,smithwicks , ect.and better luck with spoons as the water temp warms up.pay attention to the wind direction there i personally have better catches trolling into the wind.the browns last year you couldnt keep of your lines and the salmon where there as well.it was a really good year there last year with the salmon being there that earlly.i just moved to oswego permentally.good luck
