For the most fun - Extra 230. Fun aeroplane with no vices (that I could ever find)! In the early days, a mishandled spin recovery (forgot to take off the anti-spin rudder - DOH!) simply resulted in a power-off full rudder side slip with no inclination to flick out. I could almost hear her saying "Really? You'll have to work harder than that"!
