pin location and ball drilling

[tracy]

i am having a ball plugged and re-drilled and the pro shop was trying to expain the different pin locations for different effects it has on the ball. is there a site that would show me the different pin locations and effects that drilling would have on a ball to give me a better idea to what is going on?

Well to get you started-
From ballreviews faq's:

AFFECT OF PIN PLACEMENT
Pin to PAP distance:
0" - minimum flare potential, core is in its most stable position, earliest roll with smoothest arc.
1 1/8" - 1/3 of flare potential, stable core position, earlier roll with smooth arc.
2 1/4" - 2/3 of flare potential, semi stable core position, early roll with strong arc.
3 3/8" - max flare potential, most unstable core position, medium length with the most hook potential.
4 1/2" - 2/3 of flare potential, semi stable core position, late roll with flip/arc reaction.
5 5/8" - 1/3 of flare potential, stable core position, later roll with a flip reaction.
6 3/4" - minimum flare potential, stable core position, latest roll with strongest flip.
Remember : These reaction characteristics are all relative to the conditions they are being used on and may not perform as expected due to burning up too early or not setting up early enough.
Pin to grip center (GC) distance: The higher the pin above grip center the more length you will get for given pin to PAP distance. The placement in relation to GC also affects where the tracks of track flare intersect (bow tie). Higher pin = Higher intersection. For this reason they suggest high trackers place the pin higher above GC to reduce the risk of flaring over the finger holes.

AFFECTS OF MASS BIAS (MB) PLACEMENT
As the angle goes from 75° (strong/flip) to 0° length will be reduced and have more of an arc reaction. From 75° to 105° length will increase and have more of an arc reaction. Beyond 105° the reaction will keep a very similar reaction but with more length.
Remember : These only enhance the characteristics of the given ball and Pin placement and the flip (strong) position may not necessarily have the biggest backend reaction on given condition due to many other variables that affect ball reaction (bowlers specs, lane condition, etc.)

bowl1820, thanks for the info. one of the guys i bowl with gave me his brunswick diamond back today . he bowled a 300 with it against me 3 weeks ago in the scratch league so i was kind of eyeing it ever since at the pro shop and on the internet but was putting it off because of the price. i never told him that i was looking at buying one and we were just talking about my ball reaction during a league this morning, when he said he had a ball out in his car and would go out and give it to me to get it plugged and re-drilled, so you could imagine how i felt when he gave it to me!? i almost fell over. the pro shop is plugging it and we will drill it thursday so i'll go over the specs with them too. can you tell that i'm excited? thanks agian.
