With having this rule in effect this coming season, is the new rule gonna give any particular style and advantage with the added side weight allowance? Will it make a noticeable difference in reaction and/or pin carry? Asking for a friend...

The results I got differed slightly on positive vs negative side weights. But, this is the case in real life when examining a variety of styles of bowlers.

What I did find interesting more so that I am surprised not to see in this article was the impact on finger weight vs thumb weight that I played with using 2 different bowlers with very similar results.

If I drilled a ball and the ending static weight was around 0 to 1/2 oz of finger weight, then keeping everything on the layout the same and increasing the end results of the finger wight to be in the 2.5 to 3oz range the results were noticeably different. More so then comparing 3oz positive to 3oz negative on side weight. The change in total hook was reduced and the length was increased more then any weight hole option on the software.

At the same time keeping the pin placement the same and increasing the end results for the thumb weight getting closer to 1 to 2ozs resulted in sooner and more overall hook. The difference between finger weight and thumb weight was very unexpected. I almost skipped looking into it because i assumed it was irrelevant. If anything was going to affect ball reaction it would have to be more or less side weight......not so much.

I think it is interesting that USBC was unable to really test this with throwbot "allegedly". Maybe they were hoping no one else would consider it if side wight wasn't a factor. Not sure. I will play with it some more on bp and see if I can get similar results across a variety of styles of bowlers.

Can we still use a Rico drilling with out the weight hole?

Doesn't do what the creator intended without it.

New balance rules will have some possibly interesting,  but minor pacts on ball reaction.  Yhey were clearly intended to impact the 2 handers, but will also have minimal impact on them.

Maybe YOU should be running the equipment testing division over @ USBC and writing articles for BTM as well!!!!!! Keep up the great investigative work. More testing for sure from a trusted unbiased source as yourself is what is sorely needed. Thanks

I'd have a lot of fun if I got the chance to use a throwbot thats for sure….. It wouldn't be for trying to shoot 900.

Just trying to get the most of the software to help with information since my intended purpose for weight hole information is going to be useless in a year or so.

To recap this - You're seeing more length with high amount of finger weight, and more plus earlier hook with high amount of thumb weight? Also basically zero change from either positive or negative side weight? Have you tested this any further?
