Hey guys last night I had two ballsdrilled. When I got home I noticed one wasn't drilled right. I asked for a stacked drill pin over the ring and it got drilled pin over ring with cg in the palm. A label leverage you might say. I am furious but what if anything can I do? I know he'd fix it for free but I am not gonna have a brand new ball that's never been thrown plugged.

I can wheel a ball with a negative cg placement deeper than 4th arrow!

That's cause you're a beast, bro.

I think he's a ninja bowler... 

Gonna have to figure a layout for that Nuts Pearl...  Pin up or down... CG in palm or get it kicked out... Doh!!  Seriously though... Should be fun to see what that ball will do. 

Now back to your topic... & LL's questions er observations... 

Mass bias, bro! Come on, Pike! There's a mass bias! Really, CG NO MATTAH

What I have noticed is very rarely if ever does someone have the CG placed on the negative side of the ball to start. The rare situations would be if the ball was an x-out.

But, many bowling balls have negative side weight due to weight holes being added. That is extremely common. The bigger increase in the effects of the ball are going to be due to the weight hole location and not because of the shift in side weight.

Typically most bowlers deal with CGs that are either out positive for weight hole purposes or on there center grip line. That shows a difference of approx. 1/2 board in the last few feet of the lanes before the ball hits the pins. I think most will argue you can not see that when bowling and can't use that as a noticeable difference between two bowling ball layouts. When you look at this when charted out the lines overlap so much you really have to zoom in to see where they finally start to split.

Yes there is a proven difference between having 1 oz side weight, no side weight, or 1 oz negative side weight. (Almost 1 board.) Just not enough to make a rule saying how close the CG should be to the bowlers center grip line, or to be upset about the effects it will have on a bowling ball to say it is either stronger or weaker then the next.

LoL!! 

Couldn't help but notice the Bruce Lee photo behind you though... Chuck Norris would eat his lunch before Bruce could even get it out of the bag... 

I think it was absolutely great, tremendous data exchanged, the right conclusion reached, and a logical non emotional discussion from most of the participants.

Rocker, if I were you I would read every one of the 9 pages, every thread!  I'm going to.

PS, for my friend Impending Doom, remember and you will see I noted that "we" the collective set of bowlers who own the pocket for periods of our league spend our time, moving up, tucking pinky fingers, moving outside, all those things to get those corners out.  I am part of that "we", but getting high enough in the pocket is not a typical problem with a person with my axis rotation!  It's an exciting roll and an adventure nearly every night!  I just wouldn't handicap myself with a negative CG.  I bet our proshop guys like both of us!
PS yah positive CG!  And the weightholes it spawns!

Ok here is the part where I'd have to say your splitting hairs on the CG and the weight. The CG marks the additional weight in the ball added so when the balls is drilled the weight difference between the top half of the ball and the bottom half of the ball stay legal/not lop sided.

The CG holds no magical properties other then marking this additional weight/filler added to this specific location in the ball. That weight can be shifted and manipulated.

What is the difference in a ball with 1oz positive side weight and a ball with 3/4" negative side weight and a weight hole? Most bowling balls with weight holes of any size end up shifting the side weight to the negative side of the ball.

Does the ball still carry corners and enable bowlers to play deep inside angles even with 3/4 oz of negative side weight?  Easily

In this video the ball starts with no x-hole and 5/8 oz positive side weight and after the first weight hole shifts to 1/8 oz  negative side weight and then finishes with 3/4 oz of negative side weight. Is there any issue playing deep inside angles with negative side weight? No

Oh, and by the way, this topic and a few of the others recently created here have been very interesting and informational to read, so thanks to all the participants.
