Agree wholeheartedly.
I would eat
before you get on the plane and try to get to sleep asap. The sector is relatively short and arriving early morning in SYD is brutal. No matter how good the crew, it usually takes at least 1.5hrs to get the meal service done.
You can probably afford to eat on the plane leaving LHR, but your strategy of gettng to sleep and then waking early into SIN is admirable (never managed it myself).
If I break in SIN (which is my preferred method), I usually try to get on the morning QF departure from SIN which gets you into SYD in the evening. This is not available if you are using miles (unless you partner them).
I find coming back much easier.
