Very true. I noted that CofG affects inverted behavior and pitch coupling back a few posts, too. How did you set yours up with the high stab to get very little coupling? Were you at hands off inverted (and upright, of course) level flight or did you keep a bit of forward stick for inverted? If necessary, one can also raise or lower the ailerons a turn or two (at the clevis) to adjust the trim. As Eric noted, vertical uplines and down lines also become involved. Complicated thing, this perfection in flying...

On your lightweight ones what did you use for dihedral? Straight in line with only the taper creating dihedral, flat top of wing or somewhere in between these two?
