I too have read about the yellow tone of CR200, im also aware of its grain, it may be less grainy if shot at a slower speed do you think?
Some people suggest that it was a bad batch causing the yellowing, what was the expiry date on your film #2?
Others are waiting for new stock to be available, and the newest stock i see expires in 2015.
As far as provia goes, some people use filters when shooting it, but i feel it is a pretty neutral film. Provia 50 appears to be significantly different than provia 100.
