Thoughts on this balance hole?

I've been helping this lady in our scratch league.  We were discussing her equipment and she showed me this Kinetic.  She stated that she didn't care for the reaction of the ball.  Looking at the weight hole, I wanted to check the pitch on it.

It has:

7/8 LEFT lateral
9/16 REV

I weighed it and there is 0 finger/thumb, 1/4 oz side and top/bottom weight is "normal" too.  I don't understand this hole.  Unless there is a ton of top weight, why would you drill a balance hole like this?  It appears to be somewhat of a flare reducing hole location, which still doesn't make sense to me as the bowler doesn't have a very high rev rate.

Help me understand....

If it currently has 0 thumb/finger weight, it was probably put in to achieve exactly that ( or in an attempt to end up with more finger than thumb weight ), as prior to drilling it, the ball would/should have had thumb weight in it.  If the person is truly "rev challenged", thumb weight would only smooth out the reaction more and cause it to burn energy earlier.

Agreed, but why the drastic pitches...I assume to NOT alter the core.

Personally, I'd have put a low hole near the MB marking to achieve desired finger weight and side weight.

  Which would have been just fine, as long as it also achieved the goal of making it "legal" as far as thumb weight goes.

  The pitches in it appear to be an attempt to target the area directly under the cg marking.  To me, that would appear to achieve the most drastic reduction of weight in that area by drilling into the spot where more weight is concentrated in a small area.

  Me, not being "rev challenged" would also have preferred to have the weight hole placed just as you state, to allow for greater top weight and finger weight with an increase in flare potential while still reducing side and thumb weight.  Maybe it was a topweight issue and had to have a hole like this just to remedy the situation.  If it had high top weight, that might better explain it.

What are her finger and thumb pitches? The operator may have just simply left the same pitching as one of the grip holes due to negligence or forgetfullness.

Maybe it is a modification of the Morich double thumb technique.  I think it is supposed to be pitched away from the grip, though.

Her thumb pitch is 1/8 rev and 1/4 palm, basically the exact opposite of the balance hole.

Driller may have got distracted with something else when drilling this ball....dealt with the other customer then weighed the ball (kinetic) and left the drill at the pitch he had it set up with, conventional something?

I can't think of any reason why he would have pitched the hole in that way, dual thumb is not close to that.

What's the skill level of this driller, probably forgot to change the drill.

This ball probably had a ton of bottom weight after drilling the fingers and thumb.  Look at the CG location.  The CG is really below the mid-line which you know creates bottom weight.  Hell the CG is almost as low as the thumb hole.  

This balance hole was used to remove all that bottom weight.  I don't think the balance hole was used to reduce flare.

C'mon, chitown, wake up.  A balance hole in this location will decrease thumb weight, top weight and positive side weight.  It does look like one of the hole locations in Mo's double thumb technique, but I don't know why the pitches are like that.  --  JohnP

Is there any chance you've got the direction of the pitches backwards?  If the 7/8 was right and the 9/16 was forward I'd think the driller was being sure to avoid hitting the bottom of the thumb hole.  As you've stated, he's headed it toward the thumb hole.  --  JohnP

The hole was towards the thumb.

I plugged the hole and the ball was legal.  3/8ths thumb and 7/8 side....go figure.

CG down towards the thumb hole doesn't mean bottom weight! I drill most of my stuff with the CG in the thumb quadrant so I can utilize a weight hole in that area to maximize the weight removed by the thumb hole, which is Mo's dual thumb method, which I've used for years thanks to Lane #1 Gravity Balance System! Just my $.02, Bruce
P.S. typically I place the weight hole on line from Grip Center thru CG and either inside the Val, on the Val, or just past the Val!
