Yes great replies! I was looking over the aircraft even the B777-200ER would be beneficial compared to the 343,346,77W,773.
I have found operating the Airbus A330-200 to be very good on medium and long haul flights, the A300-600R is also not that bad the 332 with RR trent 772 has a burn of 42,660 as opposed to the A300-600R 41,648. On all routes that I have an A330-200 and A300-600R operating side by side the 332 has a fuel cost of around 5% less than the A300.
