Yes, Pete we need to catch up.
As far the difference in the two types of isolators it depends on several things.
Who you ask, which ones you use/try, how much hassle vs difference in performance you might get. At one time the optical was more expensive. Not so sure now. People who I trust feel that from their experience the none optical ones work just as good if using the right ones. Of course who knows what might be introduced in a few years if at all.
When I get the chance I will post a link to the CA thread.
