Having the ability or being able to select the amount of fuel or ords at the rearm pad would be a good idea for those that enjoy the challenge of flying with 1 ride as long as they can.
For example, Up a plane with 3/4 fuel for a hi alt air sweep or land and rearm for 1/4 fuel fast base defense, then to up 3/4 fuel w/rockets to attack..... all with 1 aircraft or 1 life.....etc.
Staying alive is just as much fun as doing the hunting and doing it with 1 aircraft is very challenging.
