i like using anything that the fish cant eat. Best thing to buy is a blender. Blend up chicken livers and shad so there just a liquid and spread it around where you fish. The smell draws them in and they will find Ur bait. ill fill the blender about half up with small shad and blend them to a liquid and add a little water if i have to. if you bait with something they can eat they will come in eat your bait and leave. feed works good like u said but draws alot of carp and it doesn't take the carp long to clean up the bottom and eat all Ur feed. If you fish heavy current chum in a bag or bucket under your boat and fish downstream of the chum.
