I saw some Storm and Roto stuff listed as "Pro Cg." Now, I have heard of Pro Pin, but what exactly is Pro Cg? They are asymmetrical balls, so my guess is a Cg way out of line with the pin and mass bias. Anyone know for sure?

Exactly. It's usually a ball with a CG out of line with the pin/mb by more than a set amount. I'd say greater than 1-1.5" would be Pro CG.

Well, then do they specify which way the Cg is kicked? I see where it could be useful in drilling an asymmetrical ball with the mass bias on the VAL without requiring a weight hole. If it was kicked the wrong way, you could have a crater!

Nope, not that I know of. You get what you get, so consider it a 50/50 chance. I actually prefer to see the CG to the right of my pin/mb line so I can use weaker mb placements but still use X-Holes.

I promise this isn't a stir --

If CG doesn't matter, how does it matter in a pro-CG ball?

Because it does matter where it is placed. If the CG is offset to the left (righty) you can kick the MB out to roght and not need a weight hole. If it is offest to the right you can put the MB in the 105* area and use a weight hole. In this manner, the cg is used as a tool for placing the weight hole. So, YES, the cg matters.

Whether you believe the CG matters or not in an asymmetric ball, you still have to make the ball legal. A pro-CG ball with the CG to the left of the pin-MB line will let you put the MB almost anywhere you want and not need a weight hole if you're a righty. A lefty would be restricted to putting the CG close to the thumb unless the top weight is very low. The CG would be swung away from the grip center and with normal top weight, moving the MB away from the thumb would mean you'd need an auger to drill the weight hole.

I see.

Incidentally, my pro-pin ball has an X-hole, a big one, to make it legal. I'll give you guys the layout of the rest of the ball, and you get to guess where the X-hole is.

------PIN---- (about 1 inch above ring, 5.5 inches from MB)
-------------
-----0-0-----
-------------
------------- (4 3/8 inch span)
-------------
------0------
--------MB---
-------------
-------------
-------------
-------------
-------------
-------------
------CG----- (6 inches below MB, giving total pin of 11.5 inches)

Who drilled that? An 11.5" pin, you flip it upside down, mark the spot 180* from the pin, call it the anti-pin, and use that spot like you would the regular pin. The MB stays the same, the CG stays the same. Only now instead of 11.5" you have a ball with a 2" anti-pin. No crater of a weight hole needed, nor would it be in a goofy spot.

We thought about that, and kind of decided it would be taking the easy way out. (g) We were trying to see what would happen if we drilled it "regular." It was an experiment.

And, it worked. But yes, I do have a crater hole. I wouldn't trade what I eventually got, though.
