The more surface you put on it, the earlier it will read the midlane.
I wouldn't hesitate to put 1000 dull on it if I thought it would help, however I would change balls if I got to that point.
The surface is very tuneable, you can always put it back to factory if you don't like how it reads for you both
Its pretty low volume around here in the summer, so I took the polish off, and went from the factory OBB of 1000/polish to 3000/polish.
It gets down the lane a little better and still gets around the corner just fine for me
