I am married Peter, yes - but not to Continuum. They are using a somehow transparent belt which fits quite well. One could also use a VPI round belt. I am not sure about the material. We have to search for. You can move the motor unit just a little to raise the tension - but it`s all right. Experimenting here needs to dismount the arm and remove the cover.
here is a closer pic of the Continuum belt
