I would go with the ceramics and the 5/3.5 strops, but I see the dilemma when optimizing for price as the strops cost a lot less, almost half.
I really like the ceramics though, and I’ve never jumped from 600 to them (always go via 800/1000) so I don’t know how manageable that jump is.
Another thought is, if you ever add the ceramics later, the 14/10 strops will be unnecessary and you won’t want to use them (my experience).
