Big CVs are always good to have, the danger comes when people become trapped into thinking 'Big or nothing', and some thing is always better than nothing as the RN showed in the Falklands. As much as I want to see the CVFs in service I would accept a larger number of smaller ships (eg 30,000tons) if the alternative was cancellation. Four Victorious sized CVs would provide a more flexible solution as they can be in twice as many places as two ships can (including in dock for repairs).
