With 5 legs of Asia, I think Australia's out now? I can say the rest of the destination routes will be:
* 5- (6?) Legs of Asia - Japan, Laos, Vietnam, Another SE country ( Be it Malaysia, Indonesia, the Philippines, Singapore, East Timor? )
* 2- 3 Legs of Europe?
Choosing one of the SA, CA, & AF countries:
2 Legs of Central America or 2 Legs of South America or 2 Legs of Africa?
