Supposedly the story is the ball is not spinning the same numbers now as when it was tested and approved by the USBC. It’s symmetrical so this is not a mass bias issue.
The RG is 254/255 for 15#/14# - so for there to be an illegal issue that’s a huge jump to below 246
The diff is 050/051 for 15#/14# so once again that’s a huge jump to get above 060 to make it illegal
Maybe it’s not illegal - maybe it’s just spinning substantially differently?
