Hi Peter,
10100 is not a good idea as that is right on the band edge, to avoid your signal straying out you need to be a little higher. But on 10100.8 is the Germany RTTY WX station so apart from during the day, the very bottom end is noisy as the RTTY signal is wide.
CW does take place anywhere between 10100 and 10150, though mostly between 10102 and 10130, though there are CW using above 10130 too. Here are some of the various calling frequencies or centre of activity frequencies I know of on 30m:
