After cleaning after every set, hot water bath every 50 games, my Big One is starting to loss it's steam on med-heavy conditions with 150 games on it. If I polished it, would it become a med-dry ball, and replace it with the IO for the heavier stuff. Or should I just trade it in for the IO. My med-dry ball right now is an old polished R2. Just want to know if polishing this ball at this point is worth the effort.
