Interesting to me was the full scale aerobatic guys regarding proper trim.
'' Get it about right and then compensate.''
It really is simply a matter of how much compensation 'in flight' you are comfortable with.
''comfortable'' meaning automatic, IE: un-thought.
My preferred set up for aerobatics is with about 3 to 5 degrees of sink (upright as well as inverted)
That way there is no such thing as 'neutral' !
Tiring but accurate.
Hmmm - hands off either way????
We found for our tastes -years back that simply altering amount of expo for up vs down elevator - allowed us to run MORE FORWARD cg's
The down elevator movement was a bit brighter than the up -around center.
Prior to split expo settings- this was done by altering the geometry of the servo linkages -which was more work but it did help
a bit of down pressure on the stick (very minute) for inverted flight -or straight down lines was accomplished easily
I was never able to eliminate the forces of gravity (unlike some) so I had to make do -
