When I would go out I would use corn first I would toss a buch out to the area I was fishing to attract them. You can also poke holes in a can attach a rope to it and toss it to the area to keep tge scent there. I made my own blowback rigs and would attach a couple float beads to it so that when the carp sucks the corn in and blows it out before eating it the hook gets stuck good in there lip.
Some will say you need to soak the corn in strawberry koolaid but just regular canned corn works good. Cast your line out sit back and enjoy the day
