I recently shot some Scala and billagee@redsilver.com (accidently) rated it ASA 100. I had 
the lab pullprocess it to make up for this. Ihave seen Scala rated at 
its intended speed of ASA 200. The only discernible diffewrence I saw 
was that pulled film had a definite green cast to it. This might be a 
clue as to what makes up the processing chemistry. I have since made 
enlarged negs of some of these slides. They print beautifully.
