My general formula for bream on soft, hard and vibes are
1. Structure with Oysters that have been busted open. Some oyster positions will not be a feeding ground for bream due to tide and location
2. Overcast day. The more overcast the better as they have good eyes and will very shy on lures. if its a bright day, i use a dark lure. if its an over cast day i will use something a little more vibrant
3. I give a spot 5-10 casts then move on. Even if decent follows occur, bream are shy if they arnt agressive enough to bite after a few cast and a follow, they wont bite.
4. Will have a minimum of two rods setup for bream from a boat. One is soft plastic, my favour right now is the ZMAN CrawZ. I toss it at the structure and let it just float down. The other rod is a hardbody or a metal vibe. Favourite right now is Ecogear Zs. Note the casting limits of your rod, you want a rod that will action your vibe or hardbodies. Too stiff of a rod and your lure will lack action. My favourite rod right now is a 1-3 Powerbream from nitro...
5. Early morning or late afternoon are the most productive for me. Water temperature at about 16-19° is ideal for me.
6. Persistence and movement is key, keep moving and keep trying.
