Title: Pin to CG distances
Post by: icetink on November 07, 2004, 05:35:59 PM

I'd just like to know if pin to CG distances play a large roll in Track's mass bias dominant balls.  On the drilling sheets, it speaks highly about placement of the mass bias (as oppose to CG) in order to determine reaction shape.

The guy is selling bowling balls with 4-5" pin distances.  Will drilling a ball with such a long pin distance have any negative effects on the reaction of the bowling ball?  Does it limit how the ball can be drilled?  Any input would be greatly appreciated.  Thanks!

CG plays a very minimal part when compared to the Mass Bias. It is much more important to know your PAP to properly place the Mass Bias to get the desired reaction. Surface is still very important as well!
If you have any other questions, just ask!

Thanks!

Cg makes not difference as far as reaction of the ball goes. tenpinitis is correct, you just have to watch out for static weights.

And, as a ball driller, I prefer longer (4-4.5") pins with higher (4-4.5 oz) TWs. Why? While limiting in scope of drilling patterns (without a weight hole), they do allow for more dynamics in core placement.

Hey Icetink,

Cg's don't really matter as much on an average basis but as Aus states, it can limit your drilling options if the ball has high top as well.  The more crucial part of this is where the cg is relative to the line drawn between the pin and mb.  Some balls can be more lefty or righty friendly for layout and drilling.  (IE. If you want to place mb near val, cg's left of the line are easier to drill and if the mb is placed left of thumb, then the cg is more driller friendly to the right of the line)  Hope this helps...
