Thanks Simon, I specially value your discussions, being that we're from the same neck of the woods. To answer your questions, my top 5 fruits would be: purple mangosteen, soursop, sugar apple, mangoes and chico (sorry, I don't know any of the scientific names).
I'm currently growing mangoes, atemoyas, cherimoyas, dragon fruits, guavas, chicos, sugar apples, a joboticaba and miracle fruit. I'll upload pictures later.
