MY all time fav is the Chook gut, used in conjunction with a Chicken Pellet berley.
Having said that, A live hardyhead will advance the esky tally by 40cm plus Bream. Live Herring will do it as well.
For light gear fishing for Bream, I would add a leader of about 1mtr of 20lb line. Use the Chook gut and have a plentiful supply of 2/0's on hand. They will swallow the hooks down to their ' vent ", and it is faster and easier to break the hook off, tie a new one on, and retrieve the hook during the cleaning process.
Fresh strips of Bonito will outperform just about any other bait. ssshhh !
All of the above mention baits are used .. ' un-weighted ".
Bring on Winter.............
