Choosing the bowling ball that's right for your game can be difficult, especially with so many options out there. For this reason, Roto Grip has developed Star Search™. Answer a few simple questions, and Star Search™ will suggest bowling balls that most closely match your criteria.

Current Average

Current Average would be the Average Range that best describes your scoring tempo and has the least weight when Fine-Tuning ball selection.

Ball Speed

Ball Speed refers to the speed of the ball at the time of release.

The following is a generalization of each description.
Slower: Ball speed at time of release is typically 15.0 MPH or slower
Average: Ball speed at time of release is between 15.1 MPH and 17.9 MPH
Faster: Ball speed at time of release is 18.0 MPH or greater

Rev Rate

Rev Rate is defined as the amount of rotation imparted to the ball at the time of release.

The following is a generalization of each description.
Lower: Lower Rev Rate is when the ball speed is greatly higher than the rotation. Typically Rev Rates of 240 RPMs or less would fall into this category.
Average: Average Rev Rate is when the speed of the ball and the rotation are matched. Typically Rev Rates would fall between 240 RPMs and 360 RPMs.
Faster: Faster Rev Rate is when the rotation of the ball greatly exceeds the ball speed. Typically faster Rev Rates are greater than 360 RPMs.

Axis Rotation

Axis Rotation is defined as the Direction the ball is rolling compared to the direction the ball is thrown.
Up The Back: When the direction of rotation is "end over end" and the ball is rotating the same direction as it is rolled use this measurement. If the Axis Rotation measurement is known, Up the Back is considered to be 30° or less.
In Between: When the direction of rotation is roughly 45° to the direction the ball is thrown use this measurement. The average bowler will fall into this category if the direction of rotation is unknown. If the measurement is known, In Between is considered to be any measurement between 30° to 60°.
Off the Side: When the direction of rotation is roughly 90° to the direction the ball is thrown use this measurement. If the measurement is known, Off the Side would be any measurement greater than 60°.

Lane Condition

Lane condition refers to a combination of oil length, volume, shape and the type of lane surface.

The following is a generalization of each description.
Light Short Pattern: Typically less than 36' with low volume and very strong backends
Medium-Light Short Pattern: Typically between 36' to 39', medium volume, strong backends
Medium Medium Pattern: Typically between 37' to 40', medium volume, medium backends
Medium-Heavy Medium Pattern: Typically between 38' to 41', heavy volume, medium backends
Heavy Long Pattern: Typically 40' or longer, heavy volume, weaker backends

Track

Track is defined as how close the first flare/oil ring are to the Fingers and Thumb. This measurement is used to estimate the amount of Axis Tilt the bowler imparts on the ball.
Low: Low is the measurement that should be used if the Track is 3" or more from the fingers and thumb. If axis tilt measurement is known, select Low for measurements of 25° or more.
Medium: Medium is the measurement that should be used if the Track is between 1" to 2" from the fingers and thumb. If axis tilt measurement is known, select Medium for measurements between 10° to 25°.
High: High is the measurement that should be used if the Track is within 1" from the fingers and thumb. If axis tilt measurement is known, select High for measurements of 10° or Less.

Note: It is possible to have a high tilt and still track very close to the fingers and thumb or a low tilt while tracking farther from the fingers or thumb. If the track is split between the fingers and thumb such as a typical Full Roller, please use the High measurement.
