to answer. NO. For graded paper it is fine. The common complaint with putting the CC40y filter in the light path is it makes the exposure very long. IF the print is too flat you just need to increase the development time to set your negs for that light source. You can buy a new head for your enlarger from Aristogrid.com I don't know what the price is but about $150.00 You will still need to use VC filters under the lens. I don't agree that the prints turn out flat with my cold light. I would buy the newer head if I had too.
