My Zilioli has Kronos levers on it, and of course the rubber is rotting away. These levers were bad to begin with, but I hate to change anything on the bike. I also have a pair of Speedy levers, which came off my other bike because they too sucked. But which are less bad? And would you swap them, or another option, look for a pair of Campy originals to go with the calipers?
