I am going with new or newer. I always get at least 2 - 3 new balls every year. I do have a couple of balls that will be 2 years old in a couple of months that do still kick, so I am keeping those for now. I sell my used ones for a minimal price. I personally know that the covers take a beating when you bowl as much as I do, even though I clean them regularly. I also get pretty good deals on new stuff, so I cant loose, then just win a jackpot and its paid for.
