 However, when tournaments use the more conventional oil patterns, where the oil is laid from the foul line to about 40 feet, and is dry up to the pin rack, spinning loses its advantage since friction exists.Carry is also a more reliable and consistent technique of knocking pins down on the first ball, as spinning is less predictable in terms of pin deflection, and at times can result in odd leaves - including the 5-pin and wash-outs when missing the 1-pin.A no-thumb delivery involves inserting only two fingers into the bowling ball, leaving the thumb on the outside of the ball, in an effort to create more revolutions and greater hook.
