The ASW 20 seems to have a reputation for bad behavior in some configurations. Is this reputation deserved or overblown? What has been the experience of those who have owned and flown the glider? Are some variants of the 20 better or worse in terms of handling characteristics?

You may have hit the nail when you posted "Some Configurations". Don't put in full landing flaps on an early 20 until you are on final and have the field made. You will be rewarded with the ability to land anywhere. With full flaps it is like flaring a hang glider. Do a weight and balance before you fly if you suspect any undocumented lead in the tail. Using Gerhard's CG recommendation mine stalled and flew like a trainer. I flew a friends 20 and the handling was like balancing on a pin so rigging may be an issue on some of these older ships.
Also, The notion that the 27 is "overrated" is silly. If you get a chance, fly them both and you will go with the 27.
