For those who might take issue with Johns7022's views, the importance is that such views challenge the conventions and lead to vigorous and robust discussion .. all of which should be useful for Tech Log's educational interests.
We take your point John T, but our poster johns7022 is but our old friend ssg (if it's not he's got a twin) who started the following thread and droned on endlessly about the same dreary issue, and displayed a total lack of knowledge, or acceptance of the views of the professionals, to whom this is their daily bread and butter. The ground has been well plowed, perhaps the threads could be merged.
