Sorry but I just decided to move to the "Dark Side" so I would not use color negative films much any more. However, I think I would start shooting E6 again and standardize on Fuji film as I never use Fuji slide film before. I have found that my old card board mount slides processed by Kodak go thru my projector much smoother than the plastic slide mounts used in other labs. Is the a lab out there still offers cardboard mount?
