I believe you guys. I was just reporting, to the shock of no one, that Easton denied this. They claimed it was all the grip that was the cause if there was any
Since there is no industry regulation on how bat weights are measured, they can claim anything they want. For example, Anderson uses a method more in line with "swing weight" used by golf club manufacturers. As a consumer, the important thing is understanding that a "20 oz" bat from Brand A may feel significantly different than a "20 oz" bat from Brand B. Trust what feels right to your DD over what the numbers on the sticker say.
