Have to agree with Wino on this one. EK, for eg, have opted for fuel dumping on their A330-200 because of some of their hot and high destinations and the all important single engine climb out in the G/A.
They do allow for overweight landings, in an emergency provided you meet the approach climb criteria and complete the overweight landing checklist, which calls for a V/S at touchdown for no greater than 360 ft/min.
keep smiling.
