Here's an idea for you....
Keep the Reds, but bin the frame they are currently zooming around in and give them the Harriers instead, there's a few spare now after all...
Result...
1. A whole new dimension to the display ... up 'n' down as well as just zooming around (even though they do it so well).
2. Keeps the Harrier in service and skills current which is no bad thing, you never know when an aircraft with it's unique abilities could be needed again in anger.
3. Less skill fade to cause upsets when the ships finally (if ever) come into service.
