Ok. Here is the e-mail I received from Visionary.
Dear Test Staff Member,
The following is information on the new release of the centaur:
Core Design:
This core is a modified version of our original DC Core. By removing the bottom cap, thickening the neck at the top, making the inner portion all one density and then wrapping it with a light spherical wrap, we were able to create a dynamic core with an extremely low differential.
Low RG: 2.61"
Differential: .015"
This change in core design makes the ball much more driller friendly, and most bowlers should be able to use their favorite drilling on this ball without being to concerned with killing the reaction.
Coverstock Design:
The shell on this ball is a new Green/Blue Solid Reactive coverstock. This new coverstock is very user friendly and can be easily adjusted to fit anyone's style. Out of the box, this ball will be 1,000 matte (gray scotchbrite Pad), but don't be afraid to polish or scuff it as needed for different reactions.
General Notes:
Due to the extremely low differential, this ball will have less flare potential than a lot of our previous balls. Out of the box, bowlers with a lot of hand should have success on most medium oil patterns, while bowlers with less hand may need to have slightly drier conditions for it to excel. Scuffed up, this ball will begin to roll earlier and provide a strong, continuous arc to the pocket allowing it to handle more oil. Polished this ball will go very long, and be more snappy on the backends.
This ball should be a nice general purpose ball for most bowlers, being dominant on most house conditions. This may quickly become the first ball out of your bag.
They also sent me a a picture of the ad that will be sent out to pro-shops. I don't know how to post a pic so I guess you guys will have to wait until the 28th when Visionary has it on their site. I hope this info helps...
