Voted for the GR7/9
Being ex-RAF there was no competition. The GR will always be preferred by Brits, the AV8 by Americans. Not that we are the majority but that's what will likely come of it. The AV8 has always been the Marines Harrier.
However any Harrier will rock, be it Marine, RAF or Navy, as long as justice is done to the aircraft.
Will start saving now for it :)
