I'd go for a quality groundbait (Sensas Bream, Van den Enynde Secret/Magic etc.). As stated above, bulking up with a bit of brown crumb helps keep the cost down. Fishmeal based groundbaits and pellets can also work well on venues that see lots of pellets going in.
When adding liquid try emptying the water from a can of corn, mixing with some mollasses (a superb bream additive) and then mixing away with sufficient lake water to get the correct mix.
Just to prove this works, here's a snapshot from last week!
