I originally had CRB set to send no referer and then added sites where they needed a referer into RefControl, (which was set to the default of
Normal - Send Referer), but then I changed RefControl to
Forge and CRB to set the referer as the destination, (Mode 1, equivalent to RefControl
Forge mode).
That seems to make all the sites that I've visited happy and I don't need any site specific settings in RefControl, (at least for any sites I've frequented so far).
I also run
ProxyTool so that when/if I hit a site that requires something more, I'll have the info available to input into RefControl.
