Richard Cielec suggests shimano plastic pulleys for a campy rehab. I worry that there is the issue that the bad vibes from the pulleys are going to rub off on the jockey cage, and eventually travel up to the parallelogram and make the rivets come lose, causing slop in the campy derailleur.
My personal preference would be to use cheap Suntour plastic pulleys for a campy rehab. These pulleys have the correct attitude for a campy bike. If the logos bother you THAT MUCH, then 30 seconds with a dremel should make them into "no-name" plastic pulleys. Moreover, the vibes from the pulleys won't shake your rivets loose ... *grin*.
