I have been to Como several times in the evenings with my dad when I was a little kid to fish for carp, never even had a bite. Lafarge on the other hand has a very large population that don't seem too shy. I've never gear fished for them so I don't know if the weights or anything would spook them. Coming in behind the people that feed the ducks with bread as the carp move in to get the left overs after the ducks are gone has proved to be the best time as long as the area isn't too busy. Throwing bread flies over top of them is your best bet in this situation. If you find a school and they aren't really feeding, dropping a small back or brown nymph in front of their faces or making them chase a small olive, black or brown leech can stir up a few chasers. These fish a great fighters and can sure be way more fun than those stocked trout, just remember to have a lot of backing!
