Ten-pin bowling powerful wrist position, but has the smooth timing and slide step of a stroker. Hall of Famer Pete Weber is perhaps the best-known example of a power stroker. No-thumbers and two-handers are similar in the respect that their bowling hand's thumb is not inserted into the ball. These styles create an enormous amount of hook, are difficult to master and have very few users. The thumbless one-handed style is more difficult to execute properly compared to two-handed. Generally, no-thumbers will use a less-heavier ball (usually one to three pounds lighter than their "thumb-in" ball) to make this style easier to
Ten-pin bowling a "shovel-pitch" from the side. A conventional bowling ball is designed to roll about a generally horizontal axis, and often the core is asymmetric so that the ball can hook naturally. However, in parts of Asia, the "spinner", "helicopter" or "UFO" release is more common. A ball spinning about a generally vertical axis of rotation spins like a top down the lane, and slides straighter, regardless of oil pattern. The ball takes an unconventional path along the front pins ("deflection"), creating domino effect pin action. The spin is generated by rotating the hand counter clockwise (right-handed bowlers) until the hand
