Here's my tuppence worth......
Chivenor - or "RAF Butlins" as the locals called it. Small, friendly, with little night flying, and no weekend ops, plus in a great part of the world. Also, more back seat Hawk flying than a 19 year old LAC could cope with!
Gutersloh - I was there in the late 80's. A magic time, with what seemed just about every NATO aircraft seen in the Radar pattern, visual circuit, or on the flight line most weeks. Very social too, what with a pint of "wobbly" in the "Mally" club being 50p a pop!
