I have always been astonished by campy bottom brackets. They are soooo smooth, even after thousands of (maintained) miles. Of course, I'm astonished by Phils too.

Maybe I'm just easily astonished.

but then again, I'm not astonished by Shimano cartridge bottom brackets after thousands of miles. Nor FSA's. matter of fact, I have a couple of hotrod OMAS bottom brackets that are, um...non-astonishing, to put it charitably.
