PS I put this post out here so that this wouldn't fill up a little drilling post I was doing, I was at the section of WHICH WEIGHTHOLEs Work and what they do. I didn't want that to get overwhelmed with the WHY Weightholes work.
WHY? Because I don't care! I just want to know where to put them to do certain things to the ball!
