Pin up, or down, does it really make a differance?

Both drillings create a low flare result.Originally Posted by MICHAEL
Both balls had a circular black area approximately where the PAP would be located as if the ball had been drilled there, then plugged.
In my opinion the most telling part was that the balls were thrown with a low rev release, so once the ball saw friction it went into a forward roll rather than hook across the lane.
Couple that with playing right up the oil line, and both balls will appear the same.
Disclaimer: I am not a bowling ball driller.
1. I've never seen a layout that required a balance hole by the pin.
2. I've never seen the pin below the thumb.
3. It seems to me that a better test would have been a typical pin up layout vs a typical pin down with the pin just below the fingers.
4. While the camera angle is similar to the view of the ball that we see when bowling, if the camera view was more of an overhead shot it might be possible to see a sight variation in the ball paths.
5. It's well documented that the layout is not the most significant factor in ball motion.
6. Pin placement is only one aspect of ball layout.
7. The speaker in the video admits that if the balls were laid out differently with regard to the c.g. the result would have been different.

Thats from Phoenix Ball Balancing, their the ones that use the software based on the old Compubalance software.
Which basically lays out balls To take out all imbalance in a ball (making them all low flare). I assume they used it on those balls, if so they are not going to look different.
Heres a video of a Encounter they did it to, it rolls just like the above ones.

That black mark on the ball is a permanent pap marker, just a hole drilled and plugged a different color.

Is Iceman STILL trying to disprove my video!??
Ice....it's been tested already! Drilling doesn't matter that much!!
Stop searching for videos and just make one of you and your twin deadly aims already!
P.S. I WILL slow motion your eventual video just in case you try to bump up or down the rev rate/speed...so don't try to get tricky!
P.S.S. Please have your ball driller VERIFY in the video that the 2 deadly aims are LEGALLY balanced. In my video and THIS video...balance holes were added to keep the balls legal. Thats a step many house bowlers forget...because nobody really checks anymore. I have a feeling Iceman's arsenal might fail a test or two.

Smokey this is not 'Nam', this is bowling. There are rules. Proud two-time winner of a bowlingboards.com weekly ball give-away!
I have two Mixes that are drilled different, and I get about 6-7 boards difference in hook with them.
The one I use most often is drilled dead straight over the CG, while the other has the CG pushed well over to the right, then a balance hole to make it legal.
It hooked so much that I had to enlarge the balance hole to the point the ball no longer has positive side weight.
Since they are both urethane pancake balls, the shells are the same, surface the same, so why does one hook much more?
That big balance hole causes the ball to flare, so it effectively exits the oil sooner.
When Iceboy first posted a picture of his original Deadly Aim, I mentioned that without a balance hole (which it didn't appear to have) the ball was likely to be out of USBC spec.
In fairness...I'd say somewhere around 15% of balls used in a standard house league are technically illegal. Probably 5% of those used in PBA events. No center wants to tick off a league bowler and tell them they can't use their favorite illegal ball.
Let's be realistic. The only place where your bowling balls may be checked for static legality is at the USBC Nationals. A few years ago the USBC did a series of Town Hall meetings around the country. I attended the one in Vegas. At that time, the USBC was still weighing every ball to be used at Nationals every day for a cost of over $100,000. per year. I asked why they were still doing that when their own ball motion study stated that static weight imbalances have less effect on ball reaction than the ambient temperature in the bowling center. The USBC rep kind of turn a few different shades of red and replied, "I guess they still do it because that's the way they've always done it." In an effort to justify not getting rid of static weight requirements all together, the USBC did another study which showed that a bowler, throwing a bowling ball with 8 ounces of side weight at 14 mph with a rev rate higher than Jason Belmonte's would see a significant difference in ball motion. They also stated that balls with too much static weight imbalance might fall off of the track in the ball return creating a headache for the bowling proprietors. These are the same bowling proprietors that the USBC shares a building and, most probably, a break room with. Please.
You know everything on the internet is true..........I am a French model!!
Static weights mean nothing in balls today. Changing dual angle sums can create significant changes in ball motion...........those videos are garbage!!!
