Sanding the ball may or may not make it hook more. There is more to getting more hook than grabbing the next rougher sandpaper. If you want to adjust the surface, let a pro shop do the work. You can also destroy a ball if you don't know what you are doing. Not to confuse matters. But if the ball is already biting into the lane too much, it can also hook less. The ball can hook out or roll out and stop hooking before it reaches the pocket. What surface adjustment is necessary is dependent on how you roll the ball, the lane surface, the lane oil patterns, etc. So, what is right for your center could be totally different from day to day or definately in a different center.
