Well I tried 3000 grit. I have mixed feelings about the surface. I like the reaction I see, but I have never thrown so many 9 counts in my life. I am getting "robbed" on so many shots it is ridicous. I do feel like I can find the pocket easier though, and I have more recovery on misses outside than I previously had. I think this is a ball that works best with polish. I am going to try 500 polished and see how it does on Sunday
