I'm still not sure I got that, but I would recommend the average bowler goes to somebody familiar who is knowledgeable in such matters and says something like;
Average Bowler said:
Hey, Pro Shop guy, I'm looking for a new ball.
to which said Pro Shop Guy should respond by inquiring as to the new balls purpose, something like;
Pro Shop Guy said:
Sure, what do you want it to do?
Average Bowler said:
I'm finding I can't get my current ball to turn enough in <specific circumstance>, can I get something with more hook?
Our illustrious Pro Shop Guy should then ask a few questions about conditions, preferences, and shot style (if they're not familiar). From this information, they go and talk you through the options that they've got, hopefully they'll tell you what the theory is they're working on, why they think that will be best for you, and then voila, they recommend a ball.
I used to work in a computer shop many years ago. People rarely came in and told me exactly what they wanted, I usually got "I want to buy a computer, please", or "I need a new MODEM". Only enthusiasts or wannabe's ever came in with specifics, and as the expert selling the products I'd tell them if I thought that their request wasn't going to meet their goal, and that was most of the time.
So I asked questions and made a recommendation that suited their unique requirements
So the moral of my story is, you need to talk to a knowledgeable and experienced professional (specialty pro-shop operator or one of the big brand staffers), and describe what you're looking for. There will never be a generic comparison of balls, because the value depends on the bowler and their ability. Unless every manufacturer agreed on a standard test pattern (always tested a new ball with the same shot, the same drilling, and the exact same delivery) you never get a baseline.
