g'day Ferris, thanks for your reply.
Thanks also to Scott, it feels a bit creepy to talk to somebody not hiding behind a mask here! What you seem to be saying is the only factor you consider is how you can process the flight. What would you do if a VFR flight requested approval to fly in G airspace above 10,000 (where he requires one, but you don't really give a buggar if he has one)???
