12-13 lbs balls

[Chow-Chow]

Is it worth buying a pro-performance that is only 12 or 13 lbs? Because of the core? What's the difference in reaction etc. with 12-13 lbs ball and 14-16 lbs?

I want to get my wife a ball, but she can only bowl 12-13 lbs.

Thanks,
Chow-Chow

Brunswick ,Storm/Roto and AMF Global keep real cores in their 12-13lb equipment. Brunswick uses a generic 2 piece weight block. The others alter densities and sometime reduce the overall size of the core for lighter weights
