I made the exact same choice. Moved to the Me fly widebody instead of my command at my loco. I can only say I regret it, my current job while paying much more is horribly tiring, I fly easily 1200 block hours a year. I am at almost 7 years still no chance at command while hundreds of DEC joined every year some flying 737. Id say get your command then move as a captain to the Middle East, dont be stupid, your chances at command are very low here atleast in The best airline in the world. After a few years you want to leave and eventually youll go back home which in my case is Europe and my widebody rating is useless.
