Columbia Cores?
« on: February 20, 2006, 03:32:34 AM »
Out of curiosity, does anyone know if Columbia (or any of the companies attached) have released a ball in the past few years with the Cuda/C core?  The last one I know of was the Cuda/C 2000 (or at least that's what I read)  
Thanks!

Hey the only core that is close to it is the ones used in the justice line by amf. They are almost the same just the adition of two slight longer flip blocks on top of the smaller one like a step.

I think you will find it close to what you are looking for. Have fun.

looking into it further they may not be legal anymore due to the change in the USBC changes the COR. Not sure of the exact number but I think they were very near the limit before the number was changed....

to the best of my knowledge the ceramicore and titanium cores are the same just another name.

As far as I know they are still legal as i know of several still being thrown in amateur tourneys around the northwest.  
As far as the ceramicore being the same they are just a hair different in shape. but appears very much the same the new ones are a ti/ ceramicore as the old ones did not have the titanium

what I mean by legal is to make new balls with the core.... I think any of the older ones would have been grandfathered in

after looking into it the Ti Beast Low RG is almost the same core inverted

ok here is the situation
"COR(coefficient of restitution) is the transfer of energy from one object to another; in this case, from the bowling ball to the pin. This new bowling ball specification changed the upper limit from 0.78 to 0.75 and took effect March 15,2005."
whole story here:
http://www.bowl.com/articleView.aspx?i=10098&f=1
Ceramics are known to be one of the hardest materials in a bowling ball that do not absorb energy thus transfering alot to the pins. Making the ball hit harder. Look here to find out why ceramic cores were used:
