I flew one back in 1996 when we were evaluating them for Lancs Aero Club. I liked it from the point of view of visibility, quietness and general handling, but was worried about how they'd take a constant bashing from Barton's not-quite-bowling-green surface.
Plus, you can't stall them. Dangling there with the nose at an absurd angle and all it does is waffle about losing height at a steady rate. The instructors didnt like it because of that characteristic. In the end we didnt get any. But a nice little thing. Would have done to replace the Grobs but not the PA28s.
