I've been able to throw this enough now to post a review. The Diamond Back brings back the traditional Brunswick ball motion with a bonus. This ball clears the fronts very well and has a smooth continous motion down lane. I drilled mine 70x5x40. I have played with the surface and have found that 4000 is the best match up for me. This has also become my new benchmark ball. Very predictable throughout the entire lane. I compared this ball to a Siege drilled 65x5x40. Both balls cleared the fronts great, Siege had more midlane and was smoother of the spot, while the DB cornered a little harder. These two could be a great 1-2 punch with proper layouts and surface preps. Oh and by the way with the black/yellow coloring, it looks cool going down the lane too!!

Ball Review: Diamondback
Date: 11/04/09

Bowler Information:

Initial ball Speed: 16.5 - 17 mph
Tilt: 10 Degrees
Axis Rotation: 30 Degrees
Rev Rate: 300-340 RPMs

Coverstock - Activator Solid
RG min - 2.496Ē
Differential - .043Ē

Drill Specs:
Pin to PAP - 4.5Ē
Degree From VAL: 25"
Vertical Pin Orientation: UP
Drill Angle - 65"


4000 Siaair Micropad

The Diamondback is a new reaction shape for Brunswick in the Advance Performance line. If you are looking for a reactive solid with plenty of hook at the breakpoint, look no further! This ball takes a solid read of the midlane and then explodes into the pocket with an amount of angularity I have never seen in a Solid Symmetrical Ball from the great folks at Big B. Activator Solid is known as a smooth continuous reading solid formula, however, when pared with the Rocket Core it seems to become quite a bit more angular. Don't get me wrong, it's no C System 2.5 or Wild Thing as far as response time goes, but it is definitely more angular than past Brunswick solid releases in the Advanced Performance line. In fact, the ball had too much recovery in its out of box 2000 Siaair Micropad finish for our 40 food moderate to heavy volume house pattern, so I decided to take it down to 4000 so I wouldn't have to play so far in the middle of the lane. When compared to my similarly drilled 2000 grit Rattler, the Diamondback is 3 and 1 stronger with more angularity at the 4000 grit finish. From a pro shop operators perspective, it also compares very capably with other manufacturer's solid balls that tend to have faster response times than that of Brunswick and seems to possibly have more hook. In summary, this ball continues to improve on proven technology by providing a little bit of that new Brunswick angularity. If your looking for top tier performance at an affordable price look no further...The Diamondback is all of that and more!

Good to hear positive things about the Diamondback.  I know my Sidewinders and Swarms were excellent pieces too.  Brunswick has popped out some decent equipment in the past and I'm sure they will continue too despite the naysayers.  Oh and congrats to Adam on the 3 bills!

Ball: Brunswick Diamondback


Pin 5Ē from PAP, below ring finger
CG ĺĒ below and ĺĒ to right of grip center

Initial Surface Preparation:

Box finish


To fill the benchmark spot in the tournament bag.  I have a couple of Copperheads that Iíve been using as bench pieces, and while theyíve served me reasonably well in this role, Iíve been looking for something that not only could be used to read a lane, but would also be strong enough to stay with as the condition transitions.  Iíve also tried a Rattler in this spot, but Iíve been hoping to find something that would handle more oil.

Why this ball?

The solid Activator cover on the Diamondback has proven to be versatile, and Iíve always gotten consistent reactions from the lower-RG Rocket core.  Also, for whatever reason, Iíve always had better luck with benchmark balls that have had solid covers.


The first time I threw the Diamondback was at a center with five-year-old Pro Anvilane, in a second-shift league.  The pair we drew that night has been playing tighter than the other pairs in the league, and getting the right midlane read has been tricky.  However, the Diamondback handled this condition extremely well, blending out the lane from front to back and side to side.  It read the oil without squirting, and from the dry, it made a defined move to the pocket without jerking or over-bouncing.  We did encounter quite a bit of transition during the set, but I was able to follow the oil line inward without losing recovery.  I didnít seem to have the same inside limitation that Iíve experienced with the Copperhead, as the ball continued to finish strong and kick the corners as I moved in.

Iíve also used the Diamondback at a center with HPL in front and older wood in back, on a fresh house condition.  The Diamondback read the friction in such a way that I could get my feet further left, allowing me to hook around the push, and keeping me further away from the burn in front.  I did have to make several lateral moves over the course of the set, but I was able to do so without losing my angle to the pocket.


I wasnít quite sure what to expect with the Diamondback.  With the Snake line (as with the BVP line before it), the stronger pieces have been more even in nature, while the angular balls have been weaker overall.  So you could imagine how pleased I was the first time I got the Diamondback wide of target, and saw the way that it came roaring back to the pocket.

Itís hard for me to draw a comparison between the Diamondback and other recent Brunswick releases.  Itís not quite like the Ultimate Inferno remake, because the Diamondback doesnít need to get all the way to the dry in order to make a defined turn down lane.  Itís also not quite like a scuffed Rattler, because the move that the Diamondback makes at the break is noticeably stronger.  The Diamondback definitely gives me a look that I donít have in the bag right now, and that I havenít seen in the mid-price line in quite a while.

Brunswick Diamondback
Ball Specs
The ball being drilled was a 3Ē pin out with 3.00 oz top weight.
Drilling: Pin 4" from PAP and Mb 45 degrees from PAP, 70 degrees V.A.L. Line DUAL ANGLE. Pin is below ring finger. Weight Hole on the axis. Factory Sanded 2000.

Bowler Information:
Track diameter is 11 5/8.
PAP is measured at 4 11/16 over and 11/16 up.
Average ball speed (foul line to head pin) is 13 mph.
Axis rotation is typically 90 degrees
Initial rev rate is typically 200 rpm, "Tweener"
Lane Condition and Pattern:
New Berlin Bowl HPL 9000 Panel. Oil Pattern: THS condition medium oil outsides, heavier oil inside, semi clean backends.

While I am out recovering from Hip replacement surgery, I am having my daughter Ashley test this ball for me. 180 Average 17 year old with medium to slow speed and a low spinner type track.

The Diamondback simply reminds me of a sanded Rattler. The motion and reaction is the same but just more hook. For the money, it will outsell the Copperhead by far, reason, Activator Coverstock, proven winner for Brunswick with the rocket core. High performance, low money. Will be one of the best balls for medium to oily lanes for bowlers on a budget.

From her Copperhead, the Diamondback is cleaner through the fronts but is much stronger off the dry and more angular on the backends. Overall hook is 3 and 2 stronger then her Copperhead.

Brunswick has the world's best line of midpriced balls and this ball just improved it by a mile.

Thanks for reading my review.

Brunswick Diamondback
3Ē pin
2.3 top

OOB surface (2000)

Bower stats:
19 +/- mph
300-325 rpm
PAP:  4.75Ē right

To be the ball that will read the midlane the most out of my equipment for medium patterns. The reason for using the Rico layout is that, for me personally, it gives more a little more of a hook-set look than a just a smooth continuous roll and I can only imagine that itís due to my amount of axis tilt and rotation.

On the lanes:
On our fresh 39í THS, this ball made the wall even easier to play than what it was to begin with. My best look came from throwing it with a speed of about 19 and a normal amount of hand with a laydown of 15 out to about 8 at the breakpoint. The Diamondback stood up relatively quickly but it didnít come with a lot of energy loss. It still had more than enough power to hit the pocket with some serious authority. At the same speed and rev rate, my polished Wild Thing with the pin above the bridge required a 4 board move to the outside and the same breakpoint at 8 to match up. Even from deep inside, the Diamondback still cornered with ease, but the angle just wasnít there for me to get the 10 out every single time.

On the 50uL per board Viper, the best look I had with this ball was up the twig around the 2 board and I was able to also pull it a tad and still get away with it. The Diamondback showed the same strength in the midlane and the same excellent carry. The same Wild Thing as mentioned above was able to play down the 5-6 board area. Once the twig burnt up a little I was able to play a small bank shot off the 1-2 board from a laydown of about 5 and still had more success with this than with any other ball or line.

To put it mildly, I think this ball is the one of the best solid symmetrical balls that Iíve ever had in my hands. The midlane read is exactly what I was looking for in order for that extra bit of forgiveness. I think the layout that I chose was spot on and I think that if you are ever planning on using a Rico pattern on a symmetric ball, that the Diamondback would be the ball to use due to the ballís ability to enhance the midlane.

I have had the Diamondback for about a week app 20 games on it. I am a certified bronze coach with 190 average on a tough condition burnt heads oily backends. Or moderate heads and blazing backends.  I have 17 plus ball speed with above average revs and would call myself a power-tweener.  However the lane condition really dictates what kind of ball I need to roll or throw when the heads are trashed.

For the past couple years I have been using Ebonite and Hammer stuff.  However I have gotten a couple balls that where just to drill specific for me.  (Black Widow and NVS.)  I drill my own stuff as well and after plugging and slugging multiple times with each ball i simply gave up and got rid of them.  

I have never and repeat never had that issue with any of brunswick stuff. Mexico or not.  I have owned 2 teal rhinos 1 attack zone urethane that hooked. Impact Zone, Battle Zone which I loved. A Red Fuze and a Raging Inferno.  Every one of those balls reacted accordingly and had there place.  I still love how the Raging Inferno rolls and occasionally will use it. The cover is as durable as a tank.

Its my belief that all layouts are kept simple and nuetral, you beat the lanes with your mind and physical ability not goofy ball layouts.  (Sorry to all the gear heads.)  Keep the pin 0 to 6 3/4 inch from your pap ideally between 4-5 inches.  If you got a lot of speed 3 3/8 from the pap may be helpful.  Do the rest with tayloring your grip and ball surface.  It's my guess most of you do not realize how important the grip is. if you really want to be the best you can be at this game the grip is one fundamental that should always stay on the surface. The perfect grip is a complex mathamatical problem that can only be solved over time as you progress in your game.  I'd love to say it stays the same and maybe for the elite it finally does, but for the rest of us we need to keep close tabs on it.

The Diamondback first off is a cool looking ball gotta love the black and gold  (steelers fan)  To but it bluntly this ball rolled similar to my Raging inferno but thats where it ended.  The 2000 siaar micro surface may be a little aggressive for this coverstock core combo however it does make for a nice inside line.  stand left throw right and watch the ball come back with a hard arc not really a snap.  Miss right and the ball still gets back from the ditch although I dont suggest living on the edge with this ball.  The ball hits like a tank and is the hardest hitting thing i own.  Absolutely love the ball and would recommend it to anyone drilled anyway.  can't wait to roll it this weekend in practice.

Happy Thanksgiving to all.

This ball is a MUST have for anyone out there that is in need of a bowling ball that can get through a heavier volume of oil and not lose energy down lane.

My Diamondback (out of the box finish), has a 2" pin which is drilled under the bridge of my fingers with the cg kicked out and a hole beside the thumb. It compliments my Maxx zone very well and I can go between the two when necessary. The Maxx zone is still a favorite of mine, but knowing I now have a ball I can go too when that one is not hitting so well is a bonus.

This ball has a very smooth motion for me and is very predictable down lane. I trust it to pick up an earlier roll and still continue through the pins without losing any energy. A MUST addition to your arsenal.

LAYOUT: 4.5" from PAP and below the fingers, no extra hole needed.

First of all I must say that I've been VERY pleased with the Diamondback. The factory finish read the lane a bit early for the conditions I've been seeing lately. Tweaked it to 4000 and BINGO!

This ball handles good amounts of oil, yet can still finish on the lane. Strong arc, but with more finish than the Copperhead/Wizard/Nemesis that have been very predictable balls.

This Activator solid cover is, and has always been, a favorite of mine. The Ultimate Inferno and Strike Zones were awesome for me, and this ball just continues to impress. Don't be afraid to adjust the surface to match up with your conditions. EXTREME VALUE and PERFORMANCE in the mid-price range! Thank you Brunswick.

Bowler Info:
375 RPM
16.5 MPH at the pins
PAP 4 5/8 x 1/8 ꜛ

Ball: Diamond Back   

Layout:  35į x 4 ľ x 30į  x-hole is Gradient Line P3

Initial Surface Preparation: 2,000 Siaair Micro Pad  

Lane surfaces tested on: HPL 9000 and Pro-anvilane

Observations: Super fast rev rate, clean through the front, firm breakpoint.

Conclusions: This quickly became the first ball out of my bag. Very good for reading lanes and has enough hook to handle oily lanes without over reacting to the dry boards. I found this ball to be a great compliment to the python. The python is longer and sharper while the diamond back is earlier and a little smoother. I love how Brunswick has made all theses new balls compliment other ones in the same line. You can create an arsenal that covers almost every condition without having the same reaction like you get in some brands.

As with any ball, proper matching of the bowler, ball, layout and coverstock are crucial to success. Make sure you find a well educated pro shop technician to drill your next ball and your scores will increase immediately.

Brunswick's latest addition to their Advanced Performance line is the Diamondback. The original Activator coverstock used on the Diamondback is a formula that provides proven downlane recovery, longevity of ball reaction and unprecedented durability. This ball uses the Brunswick Rocket core, providing a low RG core that when combined with the original Activator coverstock produces a ball reaction that is clean through the front with an aggressive move at the breakpoint.

    I drilled my Diamondback 60x5 1/2x65 to create a smooth continuous ball motion that will even out over/under that sometimes develops in THS and some of the shorter PBA patterns. I tested the Diamondback on a THS of 39 feet. The ball performed amazing because it gave me great control in the mid lane without over hooking down lane. Even though I drilled this ball for control but it still had tremendous continuation through the pins and awesome pin carry. I give this ball a strong recommendation for anybody looking tame down over/under lane conditions.

Ball Name - Diamondback

Bowler Specs

Right Handed
15 MPH
4000 Siaair Surface

Description - The Diamondback replaces and upgrades the Copperhead.  By adding Activator coverstock along with the proven Rocket core, this combination will provide a stronger, earlier rolling addition to this line.

Drilling - I drilled this ball 4 x 2 with a small weight hole on the axis.

Reaction - FOR ME, this is the earliest rolling ball that I have in my bag.  This ball rolls earlier than my Siege and C System 3.5.  Even when smoothed out, I just cant keep it on the lane.  I will be using this ball only while playing on longer patterns or on heavy carrydown.

Overall - If you want a very early rolling ball, you would be wise to take a long look at the Diamondback.  I will drill another one weaker with the pin over the fingers to take advantage of the stronger coverstock in the near future.

Thanks to Billy O, new product rep Brian Bever, and all the good folks at Brunswick.

The Diamondback that I chose to drill came with a 4" pin and 3 oz. top weight.
I drilled my Diamondback with the pin below my bridge 5" from my axis and the CG out at 45 degrees with an X-hole 5 1/2" from the center of my grip on a line through the CG. I left the ball with the OOB finish.
This ball reads the lanes earlier than anything else in my bag right now. The control that I get from this ball is outstanding. The rocket core gets this ball to rev up very quickly off my hand and the activator coverstock reads the lane extremely well. The ball motion is a strong continuous arc with excellent continuation through the pin deck.
I have been using this ball mainly during my Friday night competition on a THS that I was having extreme over/under issues with before drilling this ball. With the Diamondback I have been able to move in deeper and open up my launch angle. This has completely changed my look on the lanes and I have been able to score at a much higher rate than other lefties in the league who are still attempting to play straighter lines to the break point.
In comparison to the rest of my current equipment the Diamondback covers the most boards and has the smoothest motion. It is a nice step up from my C-System 2.5 when I get into heavier volumes of oil or when I need to smooth out an over/under condition.  


Drilled a second Diamondback with a layout suggested by Chuck Gardner at Brunswick.
On this Diamondback we went with a more responsive drilling at 35 X 4.5 X 20. This put the pin about an inch and a half above and left of my ring finger. After drilling the weight hole was placed in the P3 position.
In comparison to my first Diamondback this ball has a more delayed roll and a quicker response to friction at the back end. When the first Diamondback wants to read the lane too early this ball gives me more length and a more angular entry angle into the pocket. Same great hit and predictability. Great ball.  

Thanks again to Brian Bever and Chuck G. at Brunswick for all of their support!

I am very pleased with the way that the diamondback rolls for me. This ball was the only ball that I would throw for months. It was so predictable off the spot and let you know when you needed to make a move. You could watch the ball motion and determine when and where it would hook and put yourself in that zone and get comfortable and not worry about this ball over reacting. I love to watch the ball go sideways off the end of the pattern but I've gotten really use to watching certain balls smooth out and this is one of my favorites. If your looking for a stronger midlane ball with a predictable back end arc then this is your ball.
