The most used bit in pro shops is 31/32". That's what is used on almost all finger insert holes, and a very common thumb hole size. This will be the bit that goes DULL the quickest. A dull bit will temper the material around the holes to almost brittle if not careful.
The bridge gets tempered from both sides...couple that with the possibility of too much super glue causing a heating effect, and the weakest part of your $200 baby is right between the fingers...jime   Pearls are worse than solids.

There's FIRST, then everything else.



And that is why we have 14 #31/32 drill bits.  And they get resharpened two to 3 times a year.  Same goes for #1 1/8 bit, #1 3/8 bit, #1 1/4 bit, #7/8 bit.
All of these bits are used for inserts.

Also another reason for cracking around or between the fingers is the pitch some pro shops use.  Cheater pitches.  They pitch the MF 3/8 to the right and the RF 1/4 to the left on every ball.  This helps flush up the inserts when being installed.  But it also weakens the bridge!!!!

To answer your question, 999 times out of a 1000 it's not the cover of any ball, but the way they have the finger holes drilled, and the inserts installed.  A good pro shop has very little problem with cracking...jim

thanks for the input, and after talking w/ my local guy, and reading your post i gotta think its driller error, and not a Global problem  of epidemic proportions
picked up my 1st G900 product, and im impressed w/ it, and look forward to getting some more, and learning about the line
