As to the "assymetric" comment....it's simple. If I ask you what the difference is between assymetric cores and symmetric cores...what are you going to tell me? Probably...that symmetric cores are more smooth arc shape and assymetric more angular.
Asymmetric generally give you more options to obtain a stronger reaction whether it is a super rolly or super angular reaction via more drilling options. That is not to say symmetrical balls can't be both but when looking for extremes asymmetric are usually the choice. Many top players tend to stay away from asymmetric because of their extreme reactions though.
So...if I ask you to describe to me "skid/flip"....you're going to say it's where the ball skids longer...then "flips".
Yes.
So when you ask these questions...and the definition of "skid/flip" and "assymetric cores" are similar...it begs the question...how does a symmetric core 'help' a ball be "skid/flip"? Just like...why would you want a "dull" "skid/flip" ball? Isn't the point...that the ball skids? Doesn't adding surface reduce said "skidding"?
[B]On any ball pin placement is huge and on a symmetric ball it is the real key. For instance, for me i will always go pin up with a symmetric if i want more down lane reaction. It all depends on your pap, axis tilit, axis rotation. What you are looking for anytime with any degree of dull or shiny surface is where is this ball going to SLOW DOWN and what will it do when it does. If i have a dull surface and pearl surface ball with the same weight block and drilled the same and i can REPEAT 2 SHOTS IN A ROW you will see the dull ball slow down sooner played in a oil line. Entry Angle Entry Angle Entry Angle via controlling where a ball slows down and starts to make its way to the pocket.
These type of questions are where the bowling ball industry has kinda fallen flat on their face a bit...they have so many variables in their specs....that some seem to contradict each other. It lends even more to Rob's article discussion...because when a company adds "pearl, hybrid, solid"...and those things don't really mean anything...then what else doesn't really mean anything? Differential? Core (symmetric/assymetric)?
I guarantee for instance with the same drilling a Optimus Pearl and Optimus Solid with the same weight block and cover except for 1 being dull and the shiny you will see them slow down in different spots. But you have to repeat shots in order to see differences some times. What we have to remember is ball companies make these high performance balls with higher level players in mind in order to create slight variances for fine tuning. They make lower price balls for beginners that don't need to think about these differences. All ball specs and covers mean something. There is no conspiracy in the ball industry just the knowledge that people like all of us constantly are looking for a edge or a ball combination that fits our game. That is why companies are constantly trying to come up with different ideas and innovations, so they can make the game easier for us.
Ball motion/specs are based in physics. Physics doesn't change. There has to be constant truths when it comes to Physics. It can't be "well, some companies the motion as it relates to the core is different..." Nope. Can't do that. You're violating the rules of Physics. If an assymetric core gives X reaction...and you want Y reaction...then the X reaction is not preferable towards obtaining the Y reaction. If it's meaningless...then it's meaningless. Like cover materials. Either they are or are not...chemically different. And said chemical difference either does or does not affect the ball motion. The chemistry can't be "variable"...you can't pick up the ball and sometimes it chemically is one way and other times chemically a different way.
Ball motion physics would only apply if everyone threw the ball the same way the same speed on the same exact condition always. The physics of a ball are there to be manipulated via drilling, release and lane play. It is a bowlers job to learn how to do these things.
Roto Grip traditionally for the most part make more rolling types of balls and storm traditionally for the most part make more skid flip type. There is you difference within the same ownership even.
Covers do change after oil absorption, you know that.
The industry needs to be honest about what matters and what doesn't....what makes a ball go longer versus shorter...what makes a ball react in an angular way versus a smoother arc way...and those have to ALWAYS be true...not various versions of 'true' depending on the company, ball, star allignement, moon phases, and el nino effects.[/QUOTE]
It all matters we just have to be smart in our purchases and drilling and surface options in relation to what conditions you bowl on. But ultimately you have to be able to throw consistent shots and pay attention to learn differences. There are no absolute truths in bowling ball technology and reaction between different bowlers. We are all different and you have to learn what combinations of drilling, surfaces, releases, lane play works in a given situation. Again, throw the ball, watch the ball, learn learn learn.
