my nephew douglas used this ball in the illinois pepsi tournament. he finished in second place out of 150 bowlers. he is only 11 years old. he shot 169,176,208 with 159 pins of handicap for a grand total of 712. the shot was a medium oil 38 feet down with clean back ends. this ball works very well in this conduction. great product looking forward to future balls from 900 global.
