Thanks to all for the input.

I've been flying the G103 Twin II Acro. (I guess the Acro is a wasted
distinction these days.) It does indeed sound very similar to the
ASK21.

I'm glad to hear the rudder and ailerons are better balanced. I do
sometimes have trouble with my coordination in the 103.

Just a few more flights and lots of book time between me and the test.
