I agree with all the recent comments above and whilst my first post might not have been as clear as it should have been ( I had been up since 0130 that morning) at least it seems to have turned the discussion to a sensible and consensus view.
By the nature of the problems we are now considering, a split second decision will inevitably be required and because each is unique no drill or guidance will ever be provided. These situations are exactly the ones that we as aircrew are paid "high" salaries to deal with using our best judgement. I will emphasise again though, you need to be convinced that your a/c wont fly (or at least won't fly very far) to justify stopping above V1.
