I stopped using RB also. In BIAB, I export each regeneration of the RT as a wav to a folder and then bring those files into Studio One.

A while back Rustyspoon (Misha) explained partial regen, but I didn't really see the benefit because the workflow seemed the same to me, just with shorter RT's. And I never know exactly what I want until after I record and comp vocals in the DAW and start listening to everything together.
