I will be travelling on a few QF flights on my upcoming AA Oneworld award. I'd appreciate info about best seats of onboard 762/763/332. I'll most likely be on

QF 020 MNL-SYD 763
QF 439 SYD-MEL 762
QF 481 MEL-PER 332
QF 139 PER-CGK 763

The international 763 seems to be a no brainer - 1A through 5A as they are single seats. Does 1A offer better legroom than the rest (it is taken or blocked on the seatmap at the moment on QF 020, available on QF 139)

SYD-MEL on the 762 is a short flight, but are the bulkheads etc. any better than others on the Qantas 767-200?

Finally the A330-200, any recommendations for this one?

Thanks for your help.
