imho the ball makes a great difference in the bowler. For example,the virtual gravity is the ball of the next year i believe. I have never seen a ball with this profound appeal in the years i have been bowling.the honor scores and averages are blooming like wild flowers.usually you see the better bowlers with the high end monsters do well,I have seen seniors using this ball where they were only using the same ball they had used for the last 10 years and bowling well with it.
Thats just one ball ,but I know for me ,my avg. has gone up quite a bit since i my balls were stolen and i had to rethink my line up. Not only my avg.,but also my confidence in my ability and in my equipment.I am not really a better bowler.I know this for many reasons,spares,shot consistency,ability to close when needed.I have achieved a greater propensity for bigger games though .I am sure that this is largely in part to having better equipment.I use the same ball as 4 other people in adjacent lanes i shoot 240 they shoot 279.Lanes change i cant throw the same line or make proper ball change i shoot 170 they shoot 240.
Balls do make a great difference and have made bad bowlers better,but they cant make a bad bowler a good bowler,only practice and knowledge can truly do that .How many of us could shoot 230 on the cheetah with plastic,or even with their favorite ball.
