The problem we, and the manufacturers run into is the lack of standardization in the industry. For example, I consider my home house medium oil. When I bowled in Florida what that called medium was dry to me. Which standard is the manufacturer to use to describe a medium condition, the one from Florida or the one for my area. Either way, one of them is going to be wrong and not match up.
The only thing I like about Brunswick is their charts. If I’ve thrown one of their balls, a quick glance at the chart will show me what is stronger, weaker, longer, shorter, etc.
I’m like you Joe, haven’t bought a new ball in years, just try something used. Probably why so many bowlers are enamored about one company or the other, it’s almost impossible to jump from one to the other without causing overlap with what you already have or getting a different reaction than what you expected.
