Wow! those are some piggies.
For carp, I usually buy special flour (sold at local Korean fishing stores). Mix it with a tad of vanilla, for some additional scent, and it works wonders on carp. Just don't know what to do with them - since they aren't good for eating. Most of the time, release them back in the water.
I had carp bite even on trout powerbait (garlic scent).
