Have only flown the usual spammies for powered so can't really compete with some of the above but gliding
ASW 19 Just slid through the air like a hot knife through butter.
ASK 21 Two seat trainer but I used to love flying it solo. It ran as if on rails.
ASK 8. Would stay up with no effort at all. I remember spending half an hour or so one winter just circling around a guy's garden fire at about 1200'. Also did all my silver in an '8 so it has to be the good old 8 for me. Wonderful a/c. Have also flown the K18 which was a better performer but just not so chuckable as an 8. Light as a feather, I was 30% of it's take off weight....
