Not long ago 471 got quite a lot of new F. This month I saw a few times maybe 3-4 so you might be lucky.
Even if old F, I prefer to fly day time so I keep booking 471. I could never sleep well on 475 as it might take at least 4-5 hours after take off then get only a few hours before they wake me up again. My favorite is 476 leaving SYD around 10am and new F but I do see old F showing up from time to time.
