Although Denny is a recognized expert on balls and their use and drilling, I read that same article and have a big problem with this exact recommendation. No, I don't have any personal experience with a V2 particle, but I'd think that's an awfully poor design that needed that treatment to work properly. Also Denny, as an Ebonite staff memeber and professional tester, gets his balls a little cheaper than we do; so he would not hesitate to do this.
That said, a light scuffing with a ScotchBrite every 3 games will not wear a high percenatge of its cover away. Besides, if it makes a ball last longer well, in these days of ball's dying every 50-100 games, I think that would be a good thing. Scotchbrite-ing your V2P after every 6-9 games would seem to be sufficient, as long as it was cleaned fairly well after each use, which you should do with a dull ball anyway.
