I recently replaced a new chain/cassette and used the 'opportunity' to break own the Chorus hubs and re-lube. Obviously, lubing the bearings, but glopped grease on the pawls. Very quiet, so much so that I could hear others clicking - and they mostly had Shimano based wheels. After several hundred miles the click is becoming more noticable, but no where near the previous noise. Previously, just walking the bike would get stares from the clicking.
