CGNOMATTA, Coverstock and Surface Prep is 60-80%, drilling (pin up or down X-hole placement See video on brunsnick.com) 10-20%, and Core (RG, Diff) is about 10%

CG placement is only really important for the X-hole

Born a Lefty... Forced to become right handed...

All very PC answers....eagerly given.

However, except for Brunswick many companies show cg out drillings in their drill sheets for symmetric balls and these companies claim the drillings make the ball roll different.

Silly them.

But I believe them and have observed the following things.  CG out drillins are wonderful for getting the ball to roll up earlier.  However with the cg out it is difficult to get the ball to flip as hard as cg stacked drillings(ie one can't carry as easily playing deep inside with a cg out drilling).

IT is a great drillling for a hook stop reaction whether on a symmetric or on a n assymetric.

In addition the more one kicks out the cg(say on PAP) the more midlane oil volume is needed and the stronger the backends must be for the ball to carry.

Off course this only applies to all other companies balls except Brunswicks!

Luckily this question was put in the Rotogrip forum!

Phew!

I loved Nails comments...I believe completely appropriate!

Also...

I was recently asked by a fellow ball reviews member via PM what I expect 1)pin over ring and cg grip center....2)pin over ring and cg stacked and 3 pin over ring and cg out.  I'll answer the question here...

I say it all relates to MIDLANE.  cg in grip center almost no midlane smooth strong backend.  CG stackend strong midlane and flip for inside lines.  CG out = very strong midlane but requires stronger backends to carry as the backend is more of a hook set that does not generate as much attack angle.(particularly with a weighthole on PAP).

My opinions and what I've seen.

PS if a mass bias ball is used for this and the cg is in line with the mass bias I find the conclusions above just magnified!

stacked leverage on an overreactive condition will lead to the occassional split.

I have used this knowledge myself to profit from in the past.  The general rule I have is when better bowlers than myself are throwing good shots and getting splits for the smallest mistake and have a stacked drilling...I then go to a more gently reacting drilling or core to reduce my chance of splits.  There has been some  money in this decision in the past!

After all...they are better than me....but I like to beat them!
