whew..releived.. when I used the diamond ultra fine last time I had visions of being crucified by SRP for using such a barbaric method. But I have found that a clean dia hone works way faster and will polish up good using all the regular stones afterwards. In my case I use ceramics which IMO take longer to get a really keen polished edge, and then AOx on strop is definitely needed before final strop. I also found water on dia, and also on ceramics work really well.
