I did type another whole reply to you popay last night, but the forum got its knickers in a twist and it was lost....
However, the last two posts allude to the point I was making in that I don't see anywhere in the JARs that says you
cannot divert wherever you want to as long as you don't break the 60 min rule from a suitable airfield (not necessarily your destination alternate) . Having other airfields that are suitable between your destination and destination alternate would suffice, so that if you lost an engine you could then divert to one of these, no problem (well, other than the engine!)
