This is the downside of small-caps... You can't easily get rid of them...
@Jellby
I have still things to learn to understand your reply. Yes, I enjoy using - sparingly - these mixed case words with true small-caps. And the nicest they are, the hardest to go...
How do you write your mixed case word without true small-caps? Do you need four spans to describe:
mixed case? One for M, one for ixed, one for C, one for ase?
