I dont know, I know I told him to make sure he weighed it all out but I didnt stand there and watch as I was browsing the pro shop. I can find out if you'd like..
You seem pretty concerned about it. I guarantee you even if it did weigh out to be illegal, there are plenty more people using illegal balls every day that dont even know it. Dont take that the wrong way, if it weighs out bad I would definitely be punching a hole in it. I have bowled Nationals now for 4 years and I've never had anything weigh out bad, going again the first weekend in April.
