The BB's are all still going strong with not a hint of mysterious noises yet. In fact they are getting BETTER with age rather than worse. My single speed spins the cranks backwards for something like 5 or 7 turns from a gentle pedal tap.
Unfortunately the op indicated he has the outboard bearings of the Hollowtech II BB. I dont think they have been around 10 years. I do miss the old heavy, well sealed un-# type but we must move on, mustn't we.
