Dear Dr. Phil, (thee Dr of bowling balls that is)

 Having gone over the past threads of the upcoming release (CM) could you put into laymens terms the advantages of having a Assymetrical core with a strong "Z" number compared to a standard Assymet and also a symetrical core? Is there any style that might find it more advantageous or give them a new capability than with previous cores?? That question is not to pigeon hole the usage but to understand the dynamics of the core effect.

Thanks,
Joe unknowing public
