I was just offered a 767 class. Would any of you 767 guys be willing to give some updated insight on QOL?

Does the international flying go senior? Could a junior CVG FO avoid a month full of domestic night-flying? Can you sleep on the 4hr stopovers? I'm trying to imagine up to 17 days in a row of flying all night and sleeping all day... and it seems kinda rough. On long international flights, where does the 3rd pilot rest? Is it possible to sleep? How many credit hours are you averaging monthly these days? Good crews?

Also, will KF allow you to hold out for a 747 class?
