Ok, so I only know from personal experience that a 100 compression ball feels different then a 90 in that it feels like a rock came off the face of a club. Im about a 16 handicap, bogey golf, and I just cant tell the difference between all of them. I usually play Titleist balls, and stay away from top flight. Anyone have any thoughts? Today I saw a volvick crystal golf ball and wonderd what the help golf companies are thinking? Is it worth the money for the Callaways phil plays with? Pro V-1's? All opinions welcomed.
