This fish had probably never seen a rig. That is the only reason it was easier to catch than anything at home.
Carp remember being caught. It lasts about a week, and in some fish up to a year. They also learn it from the fish around them.
So the rig that worked on a wild lake in Italy is not a better rig. Those fish had not learned it yet. Take it home and expect the same, and you will blank.
What to do with that at home: change what the fish have learned to fear, not the rig. On a pressured water a strong fresh flavour can read as danger. A washed out bait reads as safe food.
Send this to whoever you are going away with next.
