Wing loading is a bit of a puzzle -unless you relate it to wing area.
For a rough idea of good aerobatic loadings
1000sq in =under 25 oz ft loading
1000-1500=25-30 oz ft loading
1500-2000=25-35 oz ft loading.
These are really based on a model which is not flown super slowly -such as a good 3D design.
I did a 800"arf recently for a ---------- which flew fine -till you tried for setting up a sinking or slow flying attitude.
That sucker would fall off so fast you could not believe it.
The loading was 30+oz ft.
My own scratch built stuf is way under the numbers noted above -but in arfs -those are good numbers.
