If my time zone calculations are right, your play time may correspond better with the Austrailians' and New Zealanders' peak time than EU peak time. So have you considered Tonberry or Behemoth? I've heard those have a lot of Oceanic players.

(They're JP servers, so I'm not sure how your ping would be. And while they're said to have a sizeable English speaking population, I'm sure there's still more Japanese speaking players there. But they may be worth considering if their peak time matches your usual play time.)
