pro cg balls

just got a pro cg pitbull off ebay and was wondering what makes it pro cg and how this affects drilling and ball motion.
If I had 6 hours to chop down a tree I would spend the first 4 sharpening the axe.

A pro cg is a blem, 2nd etc. first thing you should do is throw it on the scales and verify the cg location.

It might not be where it's marked.

PRO-CG: A Pro-CG is where the CG ends up a certain distance left or right of the Pin and PSA (preferred spin axis). If you draw a line from the PIN to the PSA on average the CG would need to be 2 ½” or more from that line. That distance will vary depending on if the CG was to the right or left. Although still categorized as a first quality ball it has limited drill options (see our Pro-CG Drilling Options) that requires a certain type of layout. Please consult your pro shop professional before purchasing one of these balls.

How or why is a Pro-CG manufactured? A pro-cg is created during the manufacturing process. When the pin area is being drilled the core can slightly shift. When the weight block shifts just a small amount (1/16” - 1/32”) it pulls the CG off the Y axis towards the Z axis. This is why on some balls you will notice the CG is a far distance away from the Pin to PSA line. These small shifts do not affect the reaction or quality of the product, but it can limit the drilling options. Therefore we offer a different set of drilling instructions and mark them as Pro CG's.
