I am in the same situation as you hammer. I have 6000 total, 1000 on the NG. I was always very keen on EK but they fly 99hrs a month without fail, all layovers 24 hrs, which is completely unsustainable. My current company we fly 80hrs and that is enough for me.
EVA looks good, but command upgrade opportunities are limited as is the case with many asian carriers where you join in the right seat (Korean, China Airlines etc).
Time to command has exploded at EK, EY, QR etc. Not much out there at the moment.
