If you have too much positive finger weight, does it hurt the reaction? i.e. 1 1/2- 2 oz? I know this is illegal, just wondering.

it retards the roll, and won't let the ball read the lane.

if you believe it has any effect at all, it would most likely be lane condition specific... I think I remember my original ball driller talking about giving more length and backend reaction... if that was indeed the case, then it would probably help a little on conditions with broken down heads, but hurt on fresh heavier oil shots and/or carry down.

positive fingers weight generally sends a ball longer and makes it snap harder in the back end, as compared to exact same ball, thrown by the exact same bowler, using the exact same drilling, thrown on the exact same oil pattern.

+ finger weight has a significant effect on pancake cored balls and an almost insignificant effect on dynamic cored balls.

charlest -- I will argue that the effect of static weights is the same on pancake cored balls and on dynamic cored balls. But the huge effect of core and MB orientation on the dynamic cored balls makes the effect of the static weights insignificant IN COMPARISON. -- JohnP

So "if" I was to drill a ball and not weigh it out and the cg was 1 1/2" inches right of grip center, there is a good chance the ball has too much positive weight. Sounds like it shouldnt' effect reaction much? If it does, mb balls are affected more?

If that effect is measured in absolute numbers, whatever those numbers might be; then the effect of pin/CG/MB in dynamic cored balls has an asbolute number that if an order of 100 or more times greater than the effect of static weights, then I'd agree with you.

But in general when we talk of influences of different factors, we usually talk in %-ages of 100. So, of all the factors that have an effect on a dynamic cored ball's reaction, static weights would possibly be on an order of less than .5%; on a pancake cored ball's reaction, they might be of an order of 5-10%. With all of this, the bowler's release, ball speed, oil pattern & amount and lane surface are the largest contributing factors.

Hunh?
From the amount of top weight in a ball, a good driller will be able to tell you how much side weight a ball, depending on where you place the CG (the heavy spot), will have after he drills it. The higher the starting top weight the more likely it is it will need a weight hole, the further you place the CG from the grip center.

If you're introducing the MB's placement into the equation, that does not affect the static weights. Only the CG's placement, the starting top weight, and the amount of weight removed by drilling your thumb and finger holes matter.

charlest -- I think we're in agreement, just saying the same thing two different ways. -- JohnP

Aren't there charts to estimate this? Also, I think lane#1 has an incredibly complicated system to set equipment up in order to end with desired static weights after drilling... I think it takes into account pin distance, starting top weight, etc, etc....
