I'd say that's fairly accurate fliion; trust me, you don't want to regularly operate into Kabul, Trivandrum, anywhere in Pakistan and exclusively fly in darkness. If you senior 777 guys take an educated guess at what your rosters will look like in the next couple of years then I can't see any junior skippers getting a chance at swapping fleets.
There are, of course, quite a few destinations around the Gulf and larger airports in India the 380 will go to, however if you look at our route map and still want the roster you've had for last 8 years of so, it's an easy decision.
Having said that, you may find that you enjoy being home more regularly when doing mostly turnarounds, I certainly do. I'm not as chronically fatigued as I was going through so many time zones and I most definitely don't miss taking the 340 West one week then East the next with no chance to get your head straight.
It comes down to a lifestyle choice.
