You wouldn't like it with a finer grit.
Much faster to burn.
I have several from numerous manufacturers in 5 3/4 and 8"
I like the Foley-Belsaw 60-80 grit the best.
These pictures show why I would like a finer grit (all three are from when the wheel was brand new - little has changed in the last 3 1/2 years of use):
As all can see I don't clean my chains.
