After some other opinions.
I tried my County Dressage saddle on Latte tonight, as i'm hankering to ride in a dressage saddle again.
It seems to fit pretty darn good, except the back curves up and the last part of the panels doesn't sit on her back.
However it is pretty balanced. I'm planning on riding in it in a week or two to see how it feels, but i'm just not sure if it will be a problem or not.
No biggie if it is, have another saddle that fits.
