What's your Bowling style?

Stroking
A Stroker releases his or her ball in smooth manner. Strokers often keep their shoulders square to the foul line and their backswing generally does not go much above parallel to the ground. This type of release reduces the ball's rate of revolution, thus decreasing its hook potential and hitting power. Strokers rely on finesse and accuracy, as opposed to crankers, who use speed and power.

Cranker

A cranker is a bowler who strives to generate revolutions using a cupped wrist or excessive wrist action. Crankers who rely on wrist action may have a high backswing and open their shoulders to generate ball speed. These bowlers often cup the wrist, but open the wrist at the top of the swing. Crankers may also muscle the ball with a bent elbow because their wrist is not strong enough to be cupped at the release. Crankers often use "late" timing, where the foot gets to the foul line before the ball; a technique known as plant and pull, hardly using any slide on their final step and pulling the ball upwards for leverage.

Tweener

A tweener (a term derived from "in-between") is a bowler that delivers the ball in a manner that falls somewhere in between stroking and cranking. This modified delivery could use a higher backswing than is normally employed by a pure stroker or a less powerful wrist position than a pure cranker. Some use the term to refer to a bowler who is simply not a "picture perfect" example of either a stroker or a cranker.

Power Stroker

This term refers to a bowler who relies on a high backswing and open shoulders to generate potential ball speed and a big hook, but uses the timing of a stroker. It can also be used to describe a stroker with a high rev rate, or a cranker with an unusually smooth release. A power stroker's release is both smooth and powerful, generating many revolutions via a wrist snap or flick of the fingers, without muscling the armswing.

Spinner

A spinner releases a ball such that it is rotating along a vertical axis (the x-axis) as it moves down the lane. Because of this motion, very little of the ball's surface touches the lane, which is what the spinner intends. The aim is for the ball to proceed until it strikes the head pin, at which time it will proceed to move down the front row of pins in the direction opposite its spin. As it moves down the row, its spin and mass deflect the pins into one another in an attempt to make them fall.

Shovel/Two-handed
A bowler can use a technique without inserting the thumb into the thumb hole to get high revolutions on the ball. The ball is often held with both hands or balanced on the forearm while the bowler executes a bent elbow backswing. The arm is never straightened and the ball is essentially pushed down the lane while the bowler rotates his hand and arm around the ball. Due to similar ball roll and revolutions to the cranker style, it is sometimes considered a variation of cranking.
