Digital BW, The Print

I work in RGB all the way through my workflow, especially when I used 
to have PS7 and use 8bit for everything.  I now have PSCS so no 
problems there!  

8bit RGB allows you to do more destructive adjustments than 8bit grey 
even though all 3 channels have exactly the same numbers in the 
channels.

You shouldn't need to go RGB-GS-RGB.
