Ah... our all time favourite pin. Allow me to add mine which is the 0.900 silver variant. As for the writeup... well, my por writing skills getting so much attention is kind of embarrasing. However, due to the crash the article was pretty messed up. So I decided to take it off the site for the moment. But sooner or later it will be available for download as a PDF document under the link provided above. Cheers, Monty
