Question
what is the major difference between a symmetrical and a  assymmetrical ball and how would you determine or some factors which to consider in choosing? is one significantly better than the other in your opinion?

Answer
Id,
Like screw drivers, or wrenches, bowling balls are tools.

Different core dynamics (symmetric vs. asymmetric) can help provide different ball reactions. That is why different layouts using the same ball can create different roll characteristics (looks) on a lane. Similar to different size screw drivers or wrenches working better for different kinds of jobs. When you roll a ball that works well, often variations of the same ball (drilled weaker or stronger), or the same core in different coverstocks, makes for great complimentary "tools" to the original.

Generally, a symmetric core reflects the users skills (positively or negatively), as there are no unbalanced lips, knobs, caps, etc. hanging off one side and not the other. Some symmetric cores are contained in less expensive products (they are easier, one pour elements, cheaper to make). Higher priced symmetric s feature high performance, stronger covers. The symmetric ball can become asymmetric when the core gets drilled into, but I digress.

Asymmetrical cores, for want of a better term, are stronger "engines" developing more torque and flare than the typical symmetric core.

As a ball rolls, the design intent of an asymmetric core ball is to help the bowler generate more hook/roll/hit. Some weaker handed players use asymmetric cores for the improved dynamics getting more hook/recovery helping save errant shots from poor results. Stronger players might use an asymmetric core ball for the recovery aspect, but also benefit from better entry angles when using a deeper line, strong flare potential to manage heavier oil, or stronger roll (less deflection) better "hit."

Core dynamics are another element of a ball to consider when seeking to match characteristics of a players style to the environment (lane surface) and lane condition (oil). Ball speed, rev rate, axis tilt and rotation needs to match the lane and intended ball path, utilizing ball surface and it's preparation to core dynamics/ball layout.

Back in the day, a ball was a ball was a ball. Bowler's skill dictated the results. The technological improvements in the last twenty years, as well as changes in the environment (lane surfaces and oils), have created more volatility. Lanes can create great consistency and friction potential. Cleaning and oiling machines and procedures help make the environment pristine and incredibly consistent. The forces imparted by a bowler, that would hook a rubber or plastic ball 5 inches, cause some of the new technologies to cover 10 times that.

Finally, there are no magic bowling balls. Just tools. Balls must match you to your needs. The fun part of our sport is, sometimes not so good can still be helpful, and getting matched up CAN BE Magical. Thanks for the questions. Bowl well.
