I had a span drilled an inch to short once. Yup, 1 whole inch. He said he would have to order another ball, and have it ready the next week. I said, I would still take the ball, if he gave to me for his cost. He happily complied. So, I had him plug it and re-drill. Doesn't hurt the ball at all. I suggest trying to get the balls at cost. Then decide what you want to do with the balls from there.
