I am interested in purchasing the maxxed out, but I want to stay with symmetric cores, and I'm not convinced that the core is actually symmetric. I notice listed as symmetric in most reviews, but I did notice one online seller that said it was asymmetric. To me it is not symmetric in the true sense of the word, and I'm sick of buying asyms that just don't get it done for my style of bowling. Also, the Alpha-Max list the I block as asym. If they are trying to say that adding a center mass to the I block makes it symmetric, I'm doubtful (but admittedly I have no real idea...)

Has anyone had enough experience with the core to speak confidently that it is symmetric?
Thanks

There are several versions of the I block core.   The one used in the Alphamax was but the version used in the Maxxed out is most definitely symmetrical.

Maxxed out has a low intermediate diff (under. 008) so it symmetric! All balls under .008 are symmetric, (and no im not getting into the track conversation of intermediate diff. Brunswick is doing the line so that the pearls are asyms and the solids are syms. Notice, 2.5, 4.5, ultimax, all asyms. 3.5, Alphamax, and Maxxed Out syms. Read the information in front of you and not what a staffer tells you. If you dont see 2 pins, it aint asym.

Here's a thought: if you have so much trouble with asymmetrical balls that .008 would be a problem.

Then any ball you drill you'll have a problem with. Because once you drill a "Symmetrical" ball, it becomes a "Asymmetrical" ball.

the primary differences between symmetric and asymmetric balls:

1. Symmetrical Core (undrilled) - A ball where the RG (radius of gyration) values of the Y (high RG) and Z (intermediate RG) axes of the ball do not differ by more than 5% of the total differential of the ball.

2. Asymmetrical Core (undrilled) - A ball where the RG (radius of gyration) values of the Y (high RG) and Z (intermediate RG) axes of the ball differ by more than 5% of the total differential of the ball.

Symmetrical drilled balls yield small differential ratios. Small differential ratios will produce a smooth, controllable motion when compared to an asymmetrical ball.

Asymmetrical drilled balls show a defined, angular motion. These balls can create more area at the break point and will respond to friction faster at the break point than symmetrical balls.

Aloar, that's a great observation, thanks for bringing it up. I also appreciate the definition of sym and asym. Consider this:
Over the last 10 years I've had 7 "asym" balls, each time trying to make it work (I'm stubborn). I also took the time last year to chart in Excel each ball I've had over the last 15 years, (although my wife wishes I'd stop buying so many and clean the closet.). With 100% accuracy, each "asym" ball was a non-starter, at least for me. I don't claim to have the answer, and always kick myself for trying yet again, but there are many of us on the board here who express the same view. Now, whether the answer lies along the lines that the relative addition to the "asymmetry" introduced by drilling is minimal as an overall component, or it happens to stay below some magic threshold... I don't know. I wish I did. However, as I told myself after buying my last "asym" ball, when the %^&* am I going to learn?

By the way, in the definition you provided, a ball with 5% difference on a .050 diff would be .0025, right? By that definition and provided my math is right, the .008 number for a Maxxed would be considered an asym at its baseline.

Not trying to overthink this, but it's important to understand what works for me, and starting asymmetry at .008 (if correct) has never worked.

Now, simply channeling Mo Pinel and saying that all balls become asyms is like saying "the lane has oil". Of course it does, but there's much more to the story. How much asymmetry is introduced, 2%.. 20%? I don't know.

Interesting conversation...

Sounds like you laid out you asyms with the same layout as your syms. Just a thought.

Nope, not really. For example, my Theory is 60x5x65, my Perfect Rival is 65x4x35, and my 706A is 50x4x35. Most of the syms are between (45-60) x (3.5 - 4.5) x (40-50)... Now, that's a fairly range of balls over the years, but even if they were the same the accepted delta in "identical" between sym and asym is +5 drill angle and -5 val angle, right? It wouldn't kill the ball, and I get nothing but flat....

Really though, I don't want to hijack the thread's main point. These are widely varying balls and a while different discussion.

Back to the main point. If a Maxxed out is .008, I don't consider it symmetrical. How certain are you of that number?

Not saying that the Maxxed Out is .008 because i dont know, i just know its a really good ball. Im saying that if youve ever own a track ball, especially your 706A, it was actually a symmetric. There's not enough intermediate diff for the ball to spin quickly like a true asym. So moreso, not being mean, but it was either a bad layout or you didnt matchup with the ball. Not because the ball was asym but maybe because you needed a stronger layout or maybe you werent matched up on the right condition. As a lefty, you dont really need a lot of asyms (i dont have that many) but i love having the ability to get in deep and get the ball to recover without having to change hand position. I just dont think you should condemn asyms especially with the three you named (just as an example) were more condition specific.

Here's the reply I received back from Larry Verble:

Larry Verble The core is symmetrical. So there is not an intermediate differential before drilling.

I hope this helps Lefty50!!
