Don't know if this is any help. 
 
The reflex position on the 235 airframe (same wing as the = 320/360=20 wing) is up from the faired in with the fuselage position, which is 0=20 degrees.  -9 degrees is 0.75" (3/4") up from the fuselage.  So = you=20 could interpolate the distance to come up with the amount you are = thinking of=20 changing to.

Chris,

today I made a picture during Cruise with Autopilot at 7500ft = with=20 following configuration:
770 kg  40l in header, 20l in each wing (80l total), 75kg = and 83kg=20 for pilot and co.
Flap was on 7=C2=B0 reflex  CG 26,20"  
My design CG is 22,8  -  30,3 from firewall back,=20  horizontal was installed - 0.6=C2=B0

So it looks like if I would add more reflex than 7=C2=B0, I would = need more=20 down elevator.
So the gain with the higher reflex would be lost with the down=20 elevator....=20

Christian
