Joe,
The thing to remember about sanding or using abralon is to know the basic premise of ball surface. The lower the grit, the more surface the ball will have. So, if you are wanting the ball to grab the lane and roll earlier, then you want to go for a lower grit. If you have a flood, then I would go 500 (just like the Infinite One oob). If you have a good MED/Heavy, then go for around 1000 or so. The lighter the condition, the shinier you want the ball and the less surface you want so that the ball can get down the lane without burning off all energy it may have. More oil calls for more surface and vice versa. Of course this is only basic and depends on how you throw the ball (speed, tilt, rotation, etc). For basic cleaning, I would go 1000, 2000, 4000 in order to get dirt and bring you back to whatever surface you are looking for.
