Maybe you should ask this on the relevant fora? The only downside of OZ in F is the small video screens but otherwise it's a pretty good all round premium product. Just take PJs that are two sizes larger than you'd normally take. The lounge isn't as opulent as some but is quite up to the task of feeding and lubricating you before the flight. Haven't flown Air China's F but its J/C was as good as any with lots of leg room. Apparently NH doesn't let you take the sweater or PJs...very anal airline.
