The 'friendly' refueller will give you the opinion of which one of the basta*d organisations makes him have to get off his bum more than twice a day to refuel those damn aeroplanes.
Honestly bigpela go out there and check them all out and make your mind up, over the years i've flown at least once all the schools at archer and the quality of the instructors is pretty much the same across the boards, it's just a matter of what sort of aircraft you want to fly, and how much you want to pay for them.
