Re: Choose one
Why grey?
Though red sounds very tempting aswell, but I would go for Blue: the ability to fly. It can come in handy in many situations. I.e. fly away during fights and dangeous situations, avoid busy traffic, never be late again, always a shortcut to reach destinations, easily get in high trees and buildings. I could always leave my appartment window open and just fly in instead of having to use the elevator.
