Hey guys, I'm fairly new at learning about how to get bowling balls drilled.  I just started to learn about where the MB needs to go to shape the reaction and how the pin from the PAP affects length.  What I need to know now is these static weights that I have heard so much about.  I know about thumb, finger, positive side and negative side....is that what "static weights" are?  Or something else?

Angst (sorry the 1st time), here's where we differ on opinions. You're basically acknowledging that there's a difference in the ball now with negative weight, as compared to when it had positive side.

When the ball had positive side, the ending CG/heavy spot, was on the righthand side of the ball. Now, with negative weight, the ending CG/heavy spot is on the left hand side of the ball.

Whether the ball has a hole in it or not, don't you think the ball will react differently because the weight is on a different side of the ball now..? The ball is reacting differently, not because of the hole, it's because the ending weight/CG is in a different location.

If the ball had a hole, in the position you put it to get 3/4 negative, but still had 3/4 positve side, do you think the ball will roll like it had negative weight, because the hole is the same place it was in the negative side ball..? =:^D

1. When drilling a hole into the side of a ball and you don't want to change the RG, which is best, a small deep hole or a larger shallower hole?

2. What does this hole drilled into the core do to the RG and Differental? Raise it? Lower it? Etc. My reason for asking here is that on some balls that should have worked for me that had the correct RG's and Differentals for my style seemed to not work as well if they had a weight hole. For example, I had one ball that the driller said was legal and I found out it wasn't. It was 3/4 oz too much side weight. A different driller put a long small weight hole into the ball and that ball plumb died right there and never worked for me again. What happened here??

3. How do you raise or lower the RG with the weight hole and how much does this raise or lower the Differental?

any guideline or favour weight of top vs side vs finger ratio ? I heard some guys like the same ratio on finger and size,lets says 3/4 oz finger and 3/4 size, how much top should it be apply to get the most carry ? some say 3:2:1. what do you think ?

T-God, in the example in item 2 that I posted which really happened, do you have any idea what might have made the ball die and never to work again regardless of what both the driller and my self tried on the cover to revive it?
