Some balls require more maintenance than others, and some, even with the proper maintenance, do not hold up as well as others. Ebonite's newest generation of oil-absorbing covers (GB on The One series, Traxion on the NV line, Violent on various Hammers,...) doesn't seem to hold up as well as some other covers. Powerkoil18 and Activator from Brunswick, Superflex, Accutread, Soaker, and pretty much all of Visionary's and Lanemasters' covers seem to hold up extremely well. If you can't get 300+ games, if not 500+ out of those covers, you're doing something wrong.
It's not all new balls, but you are picking up a lot of equipment from Ebonite-owned brands, thus I think you will see more or the short-lifespan covers than if you looked at other brands as well.
