Which one of the newer Ebonite balls has a symmetric core? Some of them say they are symmetric mass bias, what ever that means. Is the Mission symmetric or asymmetric?
Thanks for the help.

pictures look pretty asymmetric.

Because a ball with a mass bias can have an asymmetric or a symmetric core IN APPEARANCE, you don't want to know if a ball is asymmetric or symmetric. YOu want to know if a ball has a core with a significant mass bias or not.
Mass bias implies the mass is not balanced throughout the core. That is, the mass or the weight is not evenly distributed within the core.
Symmetry implies or has to do with only the appearance of the core.
Bottomline is symmetric cores can have a significant mass bias.

Before drilling, asymmetrical cores have marked mass bias, approximately
6 3/4 inches from the pin.
Symmetrical core do not show a marking.
However, just like all things in bowling, some do mark the 6 3/4 mass
and drill from there.
Ron Jr. has done many test on layouts with both.

Sorry, 2000 Red Pearl Mission comes from Hopkinsville
as an Asymmetrical cored Ball.

Symmetric cores CAN show a marked mass bias, IF the core has a significant mass bias, as I said above.
