Sunday I bowled with my nephew in an adult youth tourney.
I used the Dark Star during the set and my nephew used a Cell.my nephew who is left handed threw a 676 series for his set and I used the Dark Star shooting a 791.
This ball is awesome! It is so sick when it hits the pins. It is very predictable with no over under.
I drilled it with the pin next to the ring finger and cg kicked out. Almost a 5x3 w / the weight hole 5 5/8 from center of grip through the cg. Down next to thumb about 3-4 inches away from the thumb. This gives it some flare on the back.
I wrapped a ten pin in the tenth frame of the third game just missing 800 out of the box.
This ball is going to help strengthen your arsenal for sure.
