Factory finish is 4000. If the problem is the backend is too strong, you can take it to a lower grit, which would make the ball start up a little sooner and should mellow the ball (make it arc more).
Take it back to the pro shop and ask them to throw a coat of polish, which would delay the hook.
Maybe the ball is drilled too strong for where you are using it, so either leave it in the bag for heavier oil or get it redrilled.
