Does anybody know approximately how long it will take a ball to pick up lane shine after it was hand sanded to 360 grit? A friend of mine sanded a teammates balls down to this dreadful grit because they are dull OOB, and I assume he was drunk at the time. Tonight during league, my teammate shot one of his best series in a few weeks and attributed it to the sanding, but in reality, it was because he was on his spare game. He tore apart the right side of the lane by the end of game one, and wont listen to anything I say about it. I would really like to know how long I have to play deeper than my comfort zone to stay out of this crap.
