Q: Person1: I usually bowl with an eight ball . I like the control of a light ball . I can spin it more , so that the ball hooks .
Person2:Well . I like them a little heavier . I don't have as much control , usually bowling straight , but the extra momentum compensates for that .
Person1: Well , let's see which technique is better . I think I'll go up first ... Yes ! I hit a strike . I knocked them all down on my first bowl .
Person2:Well done . You got them all . You get 10 points and your next two bowls are added to this frame's score . I'II dry my ball off and try to knock them all down as well .
Person1: Good start . You knocked eight pins down . But you are left with a 7,10 split . Unless you can bowl a UFO-ball on this bowl , it is going to be impossible .
Person2:I certainly can try ... No ! It went straight through the wickets .
