Thanks Mark - always happy to oblige our 'customers'
This Terrier would perhaps have been near the top of my favourites although, like you, the A.O.P.9 gave me the most pleasure until another stole it's place 2 weeks ago.
I was visiting Eggedford, home of many Austers,meeting Martin and was to be given a flight in WZ662 - the real A.O.P.9

However, G-AMMS the Aiglet Trainer was out of the hangar instead and I was offered that one instead - no problem - another great favourite. Not only did I get a flight in her - I was handed the controls as well, and flew her for a while

So now that's the all-time top of the list of course.
Cheers
