Drilled Mine: pin 4" from pap cg 3" from pap great ball smoother backend real predictable I recomend this ball for med to heavy oil for hook out and in bowlers

I used to look at Dynothane as an inferior company compare to storm, ebonite, etc.  Fortunately, our high school program received a discount price for purchases of dynothane equipment so i decided to give the Au79 a shot.  I used a med to long drilling with a controllable/predictable backend reaction.  I kept the box finish on it.  I have not shot any outrageous scores with it yet (due to lack of spare shooting) but it is the first or second ball out of my bag every time.  Great carry for the most part and it reads the mid-lane well.  Overall great ball.

I have this ball drilled with the pin just above my ring finger. Coverstock is "out of box" condition. I throw on synthetics standing on 21, skidding to 10, rolling to about 5, then a smooth arch to the pocket.  It's a very forgiving ball since I seldom bend my elbow and "aim" my shot.  This ball hits like an explosive it's so loud!  I would rate this ball an easy 9 out of 10 if you're looking for a ball that bridges the gap between control and skid/snap.

Laughter is the language of the Gods.

Picked up an AU79 after returning from Team USA tournament.  Wanted a symmetric ball to try a Rico layout on and it fit the bill.  Layout was recommended by Ron Bragg of Brunswick for an Absolute Inferno.  Drilled the with pin one inch above center of grip with CG @ 45 degrees (2 inches right of thumb), placed weight hole 3" below midline on VAL.  I was worried about hitting finger holes as I am a high track bowler.  No problems with that however.

Layout has proven to be as versatile as advertised.  Gives good length with a strong but smooth backend reaction.  I have seen very little over/under with this ball.  Have bowled on old wood lanes with a variety of patterns, both THS and Sport compliant conditions and a couple of tournament shots on synthetic.  Home house is one that if you can score well there, you can score anywhere.  AU79 is fast replacing my Original Inferno as my go to ball for tough conditions.  

Dynothane's Soaker coverstock has a proven longevity which is far better than any other coverstock manufactured on the market today.  If you only buy 1 or 2 balls a year or less you should take a hard look at Dynothane equipment.  It will last much longer than anything else out there.  

Thanks for another great ball.  Keep up the great work "guys".

4 out of 3 people have problems with fractions.

female lefthander;have a blue heat by track;would the au be a good complement and how would you recommend the drill pattern for an aggressive turn to the backend?

After drilling up an old Cure and loving what it gave me, I decided to give the Element Au-79 a look.

I made a mistake in getting a used ball with a funky drill and not redrilling the whole ball. Instead, I just plugged the thumb and tried to move it to a place I could use it. Didn't work all that well.

The ball was drilled with pin above and to the left of the middle finger, and the CG swung WAY out to the right. There was a small weight hole in the ball that ended up not very far away from my PAP. Since my PAP is a little further up and in than most, I definitely was trying to fit a square peg into a round hole.

The end effect of the drilling was that I was bowtieing right in the middle of my palm almost, and clipping both finger holes and the thumb. The ball didn't do a thing but skate all the way to the pins. I could get some backend movement by laying my hand over to an extreme angle and almost spinning the ball, which pulled the track down a little and gave the ball a nice downlane projection with a bit of pop on the end.

Rather than post a full review, since that would be unfair to the ball, I'll just give generalities:

Positives -- Really good carry. The Cure is the same way. DynoThane cores do a good job of retaining energy and it shows in the pin carry department. Light hits, heavy hits, wherever the ball hit it did a good job of carrying. Also, the surface appeared to be very tunable. The ball gave me exactly what I put into it.

Negatives -- Not a lot of recovery right, even when I adjusted my axis and tilt.  Hold on pulled shots was just decent. And this may not mean anything to most of you, but the coverstock on mine and two others I've seen don't resemble the promotional photos at all. Not that it makes a difference in performance but I wish the ball companies would hire better photographers.

I just sold this ball to another BR.com member and I'm sure he'll have better success with it than I did. I'd be open to trying another Au-79 in the future but definitely not with the drilling I had on my first one.
