Not sure of durability yet but so far so good(i dented 3 2008 exogrids). The bat is basically the same thing as the '08 just with a few minor improvements. It has a coating over the carbon handle so that doesnt scratch up and a coating over the barrell so the paint wont chip (big problem with 07 and 08 exos) overall a great bat with amazing pop. somewhat top heavy but i like it from both sides of the plate.
