My old LS-3 was set up so the stick position was about the same at min
sink (straight ahead, not turning), best L/D, and--from memory--80
kts. Took a tape measure with me a few times and measured the distance
between the stick and instrument panel. That's probably a better
indication of drag caused by control deflection (if that's what you're
worried about) than trim position. I flew it mostly using the flaps,
with a little elevator to initiate the pull up and push over if I was
in a hurry. The push over at the top of a steep zoomie by going full
negative flaps, then popping them down into thermaling position as I
turned was a wonderfully smooth feeling. Thermaling itself was
whatever combination of stick and flap that worked. The end result was
the CG on the aft limit (dry). Performed really well but was pitch
sensitive in gusty thermals. I was told that was an issue with that
airfoild, shared by other gliders that used it (PIK, Nimbus II, et
al.).

I followed UH's (and Herr Waibel's) advice when I got my ASW 24 and
set the CG about 2/3 to 3/4 back in the range. Flies and performs
great. Which is good because I don't have nearly as much time to
fiddle with gliders as I did in earlier times.
