Yes, I am happy to report that some of my cuttings have 'taken' and have produced some roots, that are now visible.
All of my cuttings? No, nor would I expect that either. My loss rates were a little higher than expected, but this could be due to a slight difference in my method of keeping them - rather than cover them with plastic, I regularly sprayed with water morning and evening.
Of the plants varieties that were not successful, I will try again, maybe trying something different, or maybe not. Plenty of time to decide.
