So I'm looking at taking a trip SYD-RGN (and eventually back). No obvious availability in F, i.e. suites on A380 (not least because there is no F SIN to RGN) but even difficult finding J on the A380. So my question is, of the other craft flying the SYD-SIN route, which is the preferred option, 777-200, 777-300 and 777-300ER.
