Denise, you are correct. You might get good grain and sharpness in 35mm but at a severe price in speed. If you want decent speed, then you pay the grain price.

Also, I am working on home brew high speed emulsions, but so far the results have not matched expectations. The best is about ISO 100 with a 1 micron grain. I know that I can do better, but it will take time.
