Symmetrical VS Asymmetrical Bowling Balls [Find the Best Choice]

When it comes to choosing between symmetrical and asymmetrical bowling balls

  • Symmetrical bowling balls are more spherical in shape and have a balanced core. However asymmetrical bowling balls are less spherical and come with an imbalanced core. 
  • When you release a symmetrical bowling ball, the motion is going to be more gradual and smoother. Whereas an asymmetrical ball comes with a sharper turn and has a stronger hook. 
  • With symmetrical bowling, you get a more diverse release angle but for asymmetrical bowling, it is much less diverse. 
  • If you are a newbie or just getting started with bowling, go for a symmetrical ball. However, for professionals and someone looking for an aggressive bowling action, choose an asymmetrical bowling ball. 

These are some of the common differences between symmetrical and asymmetrical bowling balls. To get a more detailed idea about bowling and when to choose each type of ball, keep reading this article.

Symmetrical VS Asymmetrical Bowling Balls: Detailed Comparison

Let’s dive into the detailed comparison between symmetrical and asymmetrical bowling balls. 


Symmetrical bowling balls have a core that is identical from one side to another. In contrast, the Asymmetrical bowling balls have an imbalanced core structure which causes one side to be different from the other. 

For symmetrical balls, the core is more balanced and that’s why you get an overall rounded shape. 

Asymmetrical bowling balls have a more lopsided core design. This leads it to have a more pronounced and sharper motion when thrown. 


Symmetrical bowling balls have a more uniform roll whereas asymmetric bowling balls have a more angular and longer roll. 

Due to the uniform roll of the symmetric ball, you get an easier hold of the ball and that’s why it has a smoother motion. Its uniform roll also means that it flares less than asymmetrical balls.

However, the asymmetric ball’s angular roll ensures better control and precision when released. This is why you can get a quicker response to friction. Further, asymmetric bowling balls also tend to read the lane earlier. In addition to this, it tends to flare more which provides a stronger overall hook potential. 

Release Angle:

You get a wider range of release angles and styles from symmetrical bowling balls in comparison to asymmetric balls. This is because of its uniform core shape and the easiness of holding

Of course, releasing angle variation depends on your skills but if you are looking for a multi-angle release then a symmetric bowling ball is the way to go. 

Suitable For:

Symmetrical balls are the best option if you are just getting started with bowling. However, asymmetrical balls are better suited for professionals and someone with experience in bowling.

Due to easier grip and uniform core, symmetrical balls are better for newbies. If you don’t know how to aim in bowling, you can get started with symmetrical balls. It is effective for maintaining predictability at the breakpoint. 

Besides, if you are a bowler with higher rev rates and seeking a stronger backend reaction then symmetrical balls are the best choice for you. 

Whereas, asymmetrical balls are best for bowlers seeking a more pronounced and sharper motion. This is because it is effective for creating a stronger backend reaction on the lane. 

Besides, if you are someone who likes a more aggressive bowling action and early hook then asymmetrical balls are what you should go for.

Symmetrical VS Asymmetrical Bowling Balls: When to Choose What? 

The difference between symmetrical and asymmetrical bowling balls is in their core. One has it uniform whereas the other has it off-center. 

Symmetrical bowling balls are used on lighter oil conditions whereas asymmetrical balls are better for heavier oil conditions where early roll and increased flare are required. 

If you want to maintain predictability at the breakpoint then go for asymmetrical bowling balls but for a stronger backend reaction on the lane, asymmetrical bowling ball is the better option. 

For bowlers looking for a smoother release, symmetric balls are the way to go. However, for asymmetric bowling balls, asymmetrical balls offer a stronger overall hook.

So, if you are just getting started or someone who wants a predictable and more gradual motion then symmetrical is the way to go. But if you prefer a faster response to friction, sharper angle of entry on challenging lane conditions and a violent down lane motion then asymmetric balls should be the choice. 

Frequently Asked Questions (FAQs):

Do Asymmetrical Balls Hook More?

Yes, asymmetrical balls hook more. In fact, the more asymmetrical a ball is specifically rated as, the more the total differential developed to produce greater hook potential. This will lead to a stronger, quicker, and sharper reaction in the mid-lane than symmetrical balls. 

Is the Phaze 2 Symmetrical or Asymmetrical?

Phase 2 is a symmetrical bowling ball. It comes with one of the best coverstock in the industry i.e. TX-16 solid reactive coverstock. This along with the innovative core technology makes it have the strongest motion of any symmetrical ball in the world. 

Why is Phaze 2 So Good?

Phaze 2 is good because of its innovative core and coverstock technology. Its improvement in the overall core structure can be observed easily. Besides, the ball itself is very strong and can carry itself through the pins. 


In conclusion, the difference between symmetrical and asymmetrical bowling balls lies in their core and rolling motion. But whether you should go for asymmetrical or symmetrical depends on your preference. For someone looking for a more gradual and smoother motion, symmetrical is the way to go. But if you want a stronger hook and sharper reaction, an asymmetrical bowling ball is the better choice.
