Thank you for your comments. I had contacted Morich Tech Services as suggested by kotm. They replied to my email in less than 24 hours with the exact target weight hole location and explanations on the idea of target weight system. Two thumbs up for Morich Tech Services!
With the target weight hole in place, the ball reacts somewhat better down the lane and provides a slightly firmer read at the breakpoint. The next thing I want to try is to restore the ball surface to box condition (bad decision in polishing it up to high gloss) and see if it could handle more oil, any idea on how to bring it back to original box finish? I believe Brunswick Factory Compound is not available in my area but I do have access to Track and Progrip/Degree stuff. For those who have experimented with different surface on your S&A, what would be the best surface preparation for medium to heavy and heavy oil condition?
