These specs are factory reference for the model, compiled from manufacturer publications and other sources and provided as is. They may contain errors or describe a different production run, and they say nothing about the condition of any individual used ball — surface prep, resurfacing, plugging, and drilling all change how a ball behaves relative to its published numbers.
