Most equipment that gets taken into battle routinely has very different requirements than stuff. Bowling Ball Reviews - Bowling This Month. For over 2. 0 years, Bowling This Month has provided its readers with detailed and accurate bowling ball reviews of thousands of balls from most of bowling’s major manufacturers. This process started in 1. Our journey continues to this day as we constantly strive to help our readers make the most informed bowling ball purchasing decisions possible. BTM’s ball review process is 2. Our bowling ball review process has evolved over the years, as has ball technology itself. It has been our constant goal to provide as much information as possible to our readers so that they can make the most informed choices possible. All of the changes involved in this evolution have one thing in common: they were made with you, the reader, in mind. Readers themselves have suggested many of the changes. Others were made because it became apparent to us that our readers were being deprived of information that we were capable of providing. Some came about because a method or idea was agreed upon by most or all of the ball manufacturers, enabling us to be as consistent with our rating systems as possible. How we test and review bowling balls. In 2. 00. 2, through a general consensus of bowlers, manufacturers, and pro shops, we implemented our current ball testing process of using three different testers and four different oil patterns. Our three testers have delivery styles that cover the spectrum from stroker to tweener to cranker.
![]() Our standard testing oil patterns consist of dry, medium, and oily house shots and also includes one Sport- compliant condition. We feel that this testing methodology is more comprehensive and reliable than simply having one bowler testing balls on one or two oil patterns. ![]() Our newest bowling ball reviews are featured below. To find older reviews, please use the At- a- Glance Comparison Table or search for them using the site search box. Tired of just guessing with your bowling ball purchasing decisions? We drill and test hundreds of bowling balls per year to give our subscribers the best information available anywhere on the latest bowling balls to hit the market. That's why we've been the trusted partner of thousands of pro shops, coaches, and serious bowlers for over 2.

I've been a subscriber for many years now and along the way also discovered their articles could help my bowling techniques. We use standard oil patterns that are freshly- applied using a state- of- the- art Kegel oiling machine, we have standard testers, and we use standard layouts on each test ball. Additional details about the testing process are provided below. Testing environment. All ball testing is performed on Brunswick Anvi. Lane synthetic lanes. The lanes are double- stripped and then freshly oiled using a state- of- the- art Kegel lane machine. Four Kegel oil patterns are used for all bowling ball reviews: Oily: Kegel High Street (4. Medium: Kegel Main Street (4. Dry: Kegel Easy Street (3. Sport: Kegel Winding Road (3. Please visit Kegel’s pattern library website for more information on these and other Kegel oil patterns. Each ball is thrown on at least three of the four oil patterns. The reason we don’t always test on all four patterns is because we will sometimes omit the testing on the pattern that a given ball was obviously not designed for. For example, we might skip testing a low- performance urethane ball on our oily pattern, as it would obviously perform very poorly for all bowlers since this isn’t the type of pattern a low performance urethane ball is best suited for. We double- strip and then freshly oil for all testing. Our bowling ball testers. Each ball is tested by the same three testers. The testers all have different styles and they are referred to in the reviews as Stroker, Tweener, and Cranker. Understanding which tester’s style is most similar to yours will allow you to get the most out of our reviews and help you in making more informed choices when purchasing a ball. The three testers’ styles are summarized below. Stroker’s style. Ball speed: 1. MPHRev rate: 2. 25 RPMAxis rotation: 4. Axis tilt: 2. 0 deg. PAP: 3. 8. 75. This type of player will frequently play farther outside on the lane than a higher rev player. Norm Duke and Mika Kouivuniemi are examples of strokers. Tweener’s style. Ball speed: 1. MPHRev rate: 3. 20 RPMAxis rotation: 6. Axis tilt: 1. 0 deg. PAP: 4. 5. This type of player typically has a fairly high rev rate and good ball speed. Chris Barnes and Bill O’Neill are examples of tweeners. Cranker’s style. Ball speed: 1. MPHRev rate: 4. 50 RPMAxis rotation: 7. Axis tilt: 1. 5 deg. PAP: 4. 5. Crankers generally play deeper on the lane than a lower rev player. Bowlers like Sean Rash and Tommy Jones would fit this profile. All of the bowler parameter values shown above were obtained at or near the release point. When comparing the testers’ styles to your own, please keep in mind that ball speeds displayed on automatic scoring systems are measured near the pins and are typically 2- 3 MPH lower than release ball speeds due to the ball slowing down from friction as it travels down the lane. Our standard drilling layouts. Each of the three testers has a standard layout that is used on each test ball. These layouts are summarized below. Stroker’s layout. Tweener’s layout. Cranker’s layout. The above images show the approximate locations of the pin, CG, and mass bias locators relative to each tester’s specific PAP. Please remember that these layouts might look different for you due to differences in PAP. Make sure that you always work with a qualified pro shop professional to layout your equipment with respect to your PAP. If you are new to Bowling This Month, you might naturally have some questions about the various terms and ratings found in our bowling ball reviews. If this sounds like you, you’re in the right place. This article will walk through each of the elements of a BTM bowling ball review, explaining the terminology as we go. Bowler ratings table. Our bowling ball reviews begin with a summary table of the testers’ ratings on each of our four test patterns. An example tester ratings table is shown below. The Bowler Ratings table shows each tester’s ratings of the ball on our four test oil patterns. Ratings are from 1 to 1. These ratings represent each tester’s general opinion of their ball reaction on our test patterns. If any of the oil patterns have ratings of “NA”, this means that we chose not to test the ball on that particular pattern. As mentioned above, we do this in situations where a ball is obviously not suited for a particular pattern. General info table. Immediately after the tester ratings table is a table showing general information about the bowling ball. We split the general information into two sections: coverstock and core. Coverstock specs. Name: This is simply the manufacturer- supplied name of the ball’s coverstock. If the coverstock doesn’t have a name, we’ll typically print “NA”. Type: This is the high- level classification of the coverstock’s composition. The most common coverstock types are reactive solid, reactive pearl, reactive hybrid, particle, and urethane. Box finish: The surface finish of the ball when it comes out of the box. While we do often alter the surface of the balls during testing, all of our ratings are based on balls thrown at the box finish. Color: The color or color combination of the coverstock, as provided by the manufacturer. Core specs. Name: The manufacturer- supplied name of the ball’s core. If a core doesn’t have a name, we’ll print “NA”. Type: The high- level classification of the ball’s core geometry. All cores are broadly classified as either symmetrical or asymmetrical. RG: RG stands for radius of gyration and the value shown is always the ball’s minimum radius of gyration. RG is a measure of a ball’s resistance to changes in rotational speed. Technically, radius of gyration is equal to the square root of the ball’s mass moment of inertia divided by its mass. In practice, radius of gyration is measured experimentally using an RG swing, but it can also be calculated from a ball’s CAD model. RG is typically expressed in units of inches and the current USBC limits for RG are 2. Medium RG balls are harder to spin, so most bowlers will see a slight “loping” action through the heads. High RG balls are the hardest to spin since more of their mass is located farther from the center of the ball. Therefore, bowlers will usually see longer loping and later revving action when throwing a high RG ball. Total diff.: Total differential is the difference between the ball’s maximum and minimum RGs. Total differential is a strong indicator of a core’s overall strength and track flare potential. Flare is created as the ball migrates from its release axis. Large flare can noticeably reduce the length potential of the ball. Larger flare is generally considered an asset for playing oilier lanes, because the ball is presenting a fresh, dry surface on all successive revolutions. When the ball crosses from the oilier boards to the drier boards, the ball surface bonds with the drier lane to increase the coefficient of friction, which causes earlier hook and greater total hook. That is, earlier and greater hook when compared to a smaller flaring ball. Smaller flaring balls give the bowler better length and later hook. The maximum allowable total differential per USBC rules is 0. Symmetrical balls have an intermediate differential of 0. Intermediate differential is also an indicator of a core’s overall strength and track flare potential, but generally to a lesser extent than total differential. Balls with higher intermediate differentials generally have more versatility in how they can be drilled for the bowler. This can be both good or bad, depending on the skill level of the ball driller.
