You seem to know the answers well and they don't seem to mean much. Not sure a meaningful answer can be given or accepted after the fact.
The original steel balls are the cheapest and easiest to replace part of the bearings, that is if they should ever need replacement. If the other parts ever need replacement, the cones may or not be easy or cheap; the cups -- new hub time. The ceramic will inevitably wear the cups and cones faster than steel. The original bearings as delivered were exceptionally functional and durable if maintained, but you don't seem to ride any of your bikes very much. Is durability really an issue?

Dredging up an old dead thread to publicly anguish over a small done deal must be about something other than hypothetical damage and wear. Perhaps it's mostly about needing an "excuse to upgrade" which is off topic for this forum and to which I cannot speak. Good luck.
My plan was simply to try out the ceramic bearings and see if I actually noticed anything different - I can easily change them back - probably within an hour or two
Thanks for the comments
As a PS - I just discovered the 600 hub is actually designed with a bit of extra spacing - I put 11 balls in - I really should have put in 10.

So I've now got two extra balls (ouch)
