What seed to choose

Following on from my last thread link I'd like some suggestions for what grass seed to use to repair the damage caused by the earth works (photos to follow). The area with the grass I was trying to kill off will be skimmed back to remove the grass and roots and some drainage worked into the wetter areas which will leave about half of this lawn area destroyed. I'll be bringing in about 16 tonnes (more if required) of top soil to replace what has been removed and to cover the diggers damage so I'll need a seed that can do the new area and to overseed the existing, surviving area.

Suggestions please.
