Oh I don't, I'd be willing to try almost anything usually, but I just don't trust Ebonite made covers at the moment so that eliminates Hammer, Ebonite, and Columbia. As a college student and married my budget is much thinner these days so I don't have the resources I had before to take the chance that my purchase might not last. I just spent 375 on 2 balls that are now paperweights, and were as before I worked in a shop so that wasn't that big of a financial loss I've never experienced this with Storm, Rotogrip, Brunswick, or Morich equipment.
