Plastic seals, in my experience, will keep the bearings almost as clean as rubber sheilds but once plastic sheilds are broken in, they will provide almost zero rolling resistance.
My Acer ceramics are better now after 3 years than they were when they were new...the more you run them the better they get! They spin forever and show absolutly zero wear. I also have very little time as far as maintenance goes into them. I ran them for over three years in my TC3. They lasted 3 race seasons practicing of 1-2 days per week in the off season and I probably cleaned them less than 4 times a year...and this is after running on a carpet track that isn't too well maintained!
