Aust,
There's nothing really wrong with the Skipper school's fleet, it's just they get a hell of a lot of work (which I think is the case with the Tomahawks too) and they're getting a bit tired.
New windscreens on the C172s would be nice if nothing else.
Something else I didn't mention in my previous post, where else would you get to legally fly at 500 feet past the city in the open cockpit of an Agcat?
