Title: The Core on the ONE
Post by: Brickguy221 on February 03, 2006, 04:00:38 AM

Centrex Symmetrical Mass Bias


Could someone tell me what this means?

In other words what is the difference between a core listed as "symmetrical" and "centrex symmetrical mass bias"....?

Do you drill it like a symmetrical ball or like a ball with a MB? I looked at the ONE the other day and didn't notice a marked MB, but I could have missed it.

It has a marked MB.  I laid mine out as I would any mass bias ball.  

Someone remarked the other day that the core has a good resemblance to the Visionary G-3 Gryphon.  I have a G-3 and the movement is much the same as The One.  Of course, the coverstock is not even close nor other stats.  Who knows if the core densities are close either.

If I remember correctly, I think one of the Ebonite guys commented that they figured out a way to create a strong mass bias in a symetrically shaped core.  So while the core shape is symetrical, you should lay it out as you would any strong asymetrical ball.

Don't think mass bias, think preferred spin axis.  I believe I heard something about having variable densities inside the core.  Some asymmetric cores are different from side-to-side (Morpheus), some use densities to create a PSA (Storm's RAD cores), and some are otherwise symmetric but have a PSA (the current Zone core).  The Centrex core uses different densities to create a PSA in an otherwise symmetric cored ball.  They just don't show you the different density parts like Storm does.

Guys, thanks for the help thus far.

Shelley, do you or anyone happen to know the preferred spin axis on the ONE?

The reason I ask is because I am looking at the ONE, but am scared, if it has a low PSA. The last 3 balls with low PSA's like 5.0, 6.2, etc. haven't done well for me. Here is a post I made yesterday and so far have only gotten 2 replies to it, which really surprises me. Anyhow, I would appreciate it if you guys would read it and comment here about it as I surely don't want to plunk down another $200 and get a ball that won't work for me.

Based on the MB strength (0.027), I'd guess it has a <6sec spin time.  If you find those types of balls don't work well for you, you may want to avoid it.  But I really don't know what the spin time is on The One.  I think there are some Ebonite employees that post here from time to time, maybe one of them knows.

Brickguy,

PSA is not  "spin time".
PSA = preferred spin axis

Axis is line, defined by 2 points.

Spin time is time to reach PSA on a Pinel-designed machine meant to measure how quickly or slowly a ball reaches its PSA, once its ""equivalent to "rolled/bowled" on a lane"", via this machine. AFAIK!!

And how is that?

KOTM, thanks. Based on those numbers, I think the ONE just might work for me.

Now would you be willing to comment on the following problem I have? (without me having to buy the beer )

dan,

they take a radially symmetric design and ssstrrrreeeeeeeeaaaaaaaaaccccchhhhh it along a given axis.

Huh?  If this is getting into advanced ball design/physics nevermind, but if there is  layman explanation I'd like to hear it
