Dear @bonzo75 : Sorry to disturb you again but I re-read your posts and some information from your blog linked first by M Lavigne and unfortunatelly I can't find any single FACT/spec/measure that in any way could explain the FOUNDATION of all what you posted and that could change some of us opinions on that cartridge.
@mikelavigne , " then maybe understand the tech to see how it did what it did. "
Well that explain very clear our differences. My approach/common sense works different.
