Trying to decide and would like some input. Chris King's quality is hard to deny, the bike currently has a FSA on it.

I know it is overkill, but I am even considering the FSA Orbit Z ceramic over the steel ball bearings. It just seems strange to make bearings out of ceramic and remain with a softer material for the races (steel).

Also, as far as serviceability, are all three the same?

What are your opinions?
