Unlike some other companies, it appears that when Brunswick re-makes a ball, as when Bowlingball.com asks for the minimum run for, such as, the Fire Quantum, Brunswick's chemical company, Bayer, uses/used the exact same resin formula and Brunswick uses the exact same core for each ball.
I think Brunswick can be depended upon to continue doing this, as near as I can tell, FWIW. I think this is a great situation.
This being so, I wonder why Columbia's chemical company, BASF, does (OK, did) not seem to be able to do the same. Balls such as the Pulse remake was not close to the same ball as the original, a great ball.
