Close as I can figure................ 1.5 ounces!!! But, seriously, folks........ Top weight is used primarily as a tool for laying out the ball and tuning ball reaction. By shifting the weight to the right side of the ball you can make the ball skid a little further down the lane before it grabs. The further you swing the cg out away from the gip center the more side weight you'll have. Creating more side weight will allow you to add a weight or balance hole and alter your ball reaction. Example: A balance hole between the grip center and the pap will reduce the flare. A hole on the pap will very slightly reduce the flare, while putting the hole past your pap will increase the flare. So, in  a nutshell, shifting the top weight around will allow you add side weight which will allow you to add a balance, or, fine tuning hole. If you didnt have enough side weight you could not use a balance hole and still be legal.

Static weight don't matter as much with todays balls.  All the high top weight means you'll need to use a larger weight hole if the CG placement is the same between the 2 balls

Think of it this way.. if your throwing a 15lb ball.. it is 240 ounces. ONe ounce of side weight or negative side weight isn't going to effect the ball. In essence that side weight is .41% of the ball.. not significant.


Go take the little lead weights off your car tires if you really believe that.

Static weights are one thing. Dynamic weight is another. Static weights mean nothing because they are , well, static. Dynamic weight comes into play when the ball is in motion and these weights DO play a part in ball reaction. That is why you are able to tune your ball reaction and modify it's flare potential with a balance hole. Using a balance hole does one thing. It moves the dynamic weight. Moving the dynamic weight can make the ball roll up sooner, skid further down the lane, flare more, flare less, etc. So when you say static weights dont matter, you are half right. They do matter when it comes to USBC. There are tolerances that must be maintained. But once that weight is in motion it becomes dynamic and it DOES play a part in ball reaction.

But really.. I can't see static weights being really siginificant anymore with the strength of covers and cores.. just me though.


Where do you think the dynamics and dynamic weights come from?  As Greg T said, once the ball is moving, those static weights aren't static anymore.  Just like the weights on your car tires, they're a small fraction of one percent when the thing is laying there on the ground or on your car, but spin it up to a few hundred RPM and see just how unimportant they are.

Know I read this some where on BR .. don't know where but I know it was from a person I had faith in .. they indicated:

Lower top weight= more arcing reaction;
Higher top weight= More angular reaction.

Being unfamiliar with ball drillings and ball reaction I simply ask .. based on your response am I to assume that my written statement is IN ERROR?

No, it is not totally in error.

It's just that now the stronger cores and covers are much more influential in the ball reaction than the static weights.  Static weights still influence the reaction slightly, just not as much as they used to in years past.

In today's modern equipment, top weight has very little importance in symmetrical cored balls.  Since there is no MB position to worry about, you can vary the kick of the CG to get to the desired side, without having to worry about the MB.  Top weight is much more important in asymmetric balls.  Higher top weight balls limit the amount of kick you can put on a MB, simply because the side weight numbers after drilling will be very high, and very hard to get back to legal.  When I order an asymmetric, I always ask for about 2.5 ounces of top.  This allows me to drill the ball however I want, and not have to use larger and/or deep weight holes.

Some folks should take a physics class. FACT: A balance hole above pap and/or between pap and GC will reduce flare. WHY? Because you're removing weight from a certain part of the ball. FACT: Drilling a weight hole past the pap and/or below the pap will increase flare. FACT: Reducing flare makes the ball less aggressive in the fron part of the lane and stores more energy for the backend. FACT: Increasing the flare will make the ball move sooner and have a less angular look. How does all this happen? The holes arent magic, my friends. It's the weight!! Moving the weight on a sphere in motion has a pronounced effect on the tragectory. Like it or not, it's here to stay. It's physics 101. AND, the faster the revs, the more pronounced the effects will be because of centrifugal force. With the right amount of revs you make 1/4 ounce look like 2 ounces. Now, you can disagree all you like, but it wont change physics. And, as long as ball companies are making stronger cores the effects will keep getting stronger too. WHY? Because if you drill the proper weight hole you are changing the shape and balance of the core. Not that difficult, folks.
