Ah, I know what you mean but when I was having a pole around the owner asked me if I flew gliders. I said yes and he said 'I can tell, you know what the rudder is for.' I thought it handled OK but I didn't do anything extreme in it being as it wasn't mine.
Have you ever flown a 150 Aerobat? Now that does have a twitchy rudder. You kind of sail through the air chasing the slip ball around.
