This is the problem with you guys and gals. Getting all excited over which piece of heavy metal you fly should be the last thing you concern yourselves with. Where are you going to live? What standard of living will you enjoy / deplore? What options will you have down the road?
Personally, I would rather be bonded in the right seat getting real flying experience somewhere than choking on the Hong Kong pollution in a crappy little apartment with no money in my pocket. On trips as an SO, you are little more than a passenger in a pilot uniform. You will not even be allowed to do a walk-around so you can drool on the big-iron you "fly".
Honestly, the only people even considering this route should be those with little or no flying time who will do their indentured-servitude in HKG before trying to get a base as an FO. As of the current bid, the only bases available to FOs are in Oz (plenty) and Toronto (which will be full shortly as more SOs and FFOs become eligible). There are no base slots available in the UK/EU, New Zealand, or the USA.
