- Description: Coverstock: CFT 2.5 The chemistry was uniquely designed to have shaped molecular structures that produce a high coefficient of friction. Because of the shape of the molecule, when the ball goes into rolling friction, which occurs at the back part of the lane, slippage is eliminated and the ball will give you maximum entry and carry. Core: I-Block - The new I-Block core was engineered specifically for the CFT 2.5 coverstock to create maximum forgiveness, strong angles along with versatile drilling layouts. Ball Motion: With its 4000-grit micro pad finish, the C-(System) 2.5 will provide good length with a strong continuous backend reaction that matches up on medium to oily lane conditions for a wide range of bowling styles. Reaction Setup: The C-(System) 2.5 can be drilled using the standard drilling techniques developed for asymmetric bowling balls. After more than 18 months of research, development, and extensive lab and field tests, Brunswick is proud to introduce the new C-(System) 2.5 bowling ball, developed in close collaboration with Hall of Fame bowler Carmen Salvino. In addition to being a legendary bowler, Salvino conducts scientific research and holds multiple patents related to bowling ball design. This new line of performance bowling balls features Chemical Friction Technology (CFT). As Salvino explains, "The coverstock was chemically designed to have shaped molecular structures that produce a high coefficient of friction. Because of the shape of the molecule, when the ball goes into rolling friction, which occurs at the back part of the lane, slippage is eliminated and the ball will give you the maximum entry and carry. This is the advantage of chemical friction versus mechanical friction." "The chemistry is versatile enough that even if sanded or polished, it will not change the shape of the molecule. That is the uniqueness of this chemistry." The Chemical Friction Technology in the new C-(System) 2.5 is a difference you can feel!

Ball: Brunswick C-(System) 2.5


Pin 5Ē from PAP below fingers
45-degree locator line angle
(Dual-angle:  45 by 5Ē by 70)
XH on VAL, 2Ē below PAP, 7/8Ē by 2Ē deep

Initial Surface Preparation:

Box finish


To bridge the gap between the Wild Ride/Wild Thing and the ďSnakeĒ balls.  More specifically, to get recovery from the friction on conditions where the Wilds are burning up, but where there isnít quite enough dry for the Rattler and Python to make the turn in back.

Why this ball?

The intent of the CFG 2.5 coverstock that is used on the C-(System) 2.5 is to provide a stronger reaction to friction than what is currently available in the Brunswick line.  When combined with a moderately strong asymmetric core, it seemed to me that the C-(S) could give me the reaction shape that I was seeking.


The first time I used the C-(System) 2.5 was at a center with five-year-old Pro Anvilanes, on a pair of lanes that had been used for a qualifying squad for an ABT tournament.  I warmed up with the Rattler, and as long as I didnít get the ball too wide of target, I had a good look at the pocket.  I then switched to the C-(S), and found my best look from eight-and-four left of where I had started.  From there, the C-(S) was creating some hold for me, while still recovering nicely from the house track.

Iíve used the C-(System) at the same center in a second-shift league.  Typically, I donít like to use pin-down equipment in this league, for while there is plenty of free hook to the outside, the condition tends to favor a more direct trajectory to the pocket.  The C-(S) has been clean enough through the front part of the lane to allow me to play the lanes in this fashion, though, while still having enough strength in the back part of the lane to give me a good carry angle.

Iíve also used this ball several times at a center with HPL in front and older wood in back, on a fresh condition with fairly high volume in front and clean back ends.  On this condition, the C-(System) was really at home, as I could get my feet left and align myself to the dry boards, and not have to worry about whether the ball would recover.  Even on shots where I missed right, the C-(S) retained well enough to finish strong and carry the corners.


Usually, when I have a ball that is strong off of friction, it doesnít do so well at riding an oil line, and vice versa.  The C-(System) 2.5 gives me the best of both worlds, and in addition, it has that strong look through the pin deck that the Wilds and the Python have.  In addition, this ball seems to get better and better as I go deeper on the lane  Iíve yet to encounter an inside limitation with the C-(S).

The C-(S) doesnít seem to break the lane down quite as quickly as balls such as the Radical Inferno and Wild Ride have for me, and the C-(S) doesnít read transition quite as abruptly.

While I had originally viewed the C-(System) 2.5 as a ball to take me from the Wilds to the Snakes, Iím finding that, on conditions with enough friction to allow me to give away the pocket, I can stay with the C-(S) and keep following the transition deeper inside.

LAYOUT: 4" from PAP above the fingers, MB at about 50 degrees. Factory surface.

I bowl on a fresh house pattern on harder synthetics, as well as a second shift league. This ball has been great on both, but it seems to get better as the back ends start to transition and other pearls want to "skate" if they hit carry-down.

Overall ball motion is nice, but HOW the ball reads the lane is unique in my opinion. This ball doesn't know the meaning of deflection through the pin deck. It simply provides a strong move late on the lane without being unpredictable. This ball has given me the confidence to open up the lane more and more as the night goes on with EXCEPTIONAL pin carry.

Brunswick and Mr. Salvino are onto something special with this release.

Please feel free to message me in this site if I can answer any specific questions for you.

Ok I finally got to throw this enough to post a review on what I think. Drilled this gem with 55x5 1/2x35. I wanted to see a lttle more midlane than I had with my Wild Thing. I got this with out a problem. My initial thought of this ball being a bit weaker was wrong. When I put this ball at the same Sruface as my Wild Thing it was a tad stronger. The downlane motion was similar. I also compared this to a Siege drilled 65x5x25. These two were almost identical on a house shot. Had I been bowling on mre oil the CS would have been a bit stronger but not much.
I found the CS to be a great ball with great carry. I was trying various angles thorugh the front part of the lane and all of them recovered nicely and went through the pins even better. I have found a great little combo with another Siege drilled a little smoother then going to the CS and then to the WT as the Wild does have a little more off the spot as long as I get the surface right. Out of box surface on the CS and WT shows the WT with a tad more down lane. I prefer my WT at 2000.

This will be agreat ball for people needing a benchmark ball.

I drilled my C System 30 x 4-1/2 x 20.

This ball has been fantastic for me!  While the ball comes pearlized, I have found that it works best with some measure of head oil to help it retain energy for the back end.  

The ball picks up in the midlane very consistently and finishes strong through the pocket.  My rev rate is in the 285-315 range so I seldom see a ball really peel off of the spot when higher volumes of oil are used but the C System has given me a larger window on those conditons.  As the shot migrates in I have been able to stay with this ball far deeper than I had expected.  A hand position change and a little faith into the dry and the ball shreds the rack.

If you haven't tried the latest generations of Brunswick bowling balls you have left a hole in your bag.  The new coverstocks create more of the sexy snap people are looking for but still have the legendary Brunswick durability.  Game 1 and game 101 the ball will cure what ails you!

60 by 5.25Ē by 50
no hole
OOB surface

Bowler stats:
325 rpm

39í THS
PBA Scorpion (both on Pro Anvil)

I used a similar layout to what was on my Siege because I was looking for this ball to complement the Siege when it started to have trouble cornering at the end of the pattern.

Let me say this up front, I have never, and I mean NEVER, seen a ball that drives through the pins like this ball does. It was on the 30th board on several occasions as it left the pin deck after a flush hit. Nothing Iíve ever thrown or anything that Iíve seen other people throw hit like this ball does. Period.

I knew this ball would be too much on my THS but I had to test it out on it anyway just for fun. On fresh I laid the ball down on 25 and sent it out to around 6 at the breakpoint. The midlane was very strong, as was the recovery. As long as the ball was between 10 and 3 at the breakpoint, it got back to the pocket. However, between the characteristics of my center and the THS we put out, outside angles always score better compared to playing deeper, so I had an even better look amping up my speed and playing 15 (laydown) to 7(breakpoint). But it still wanted more oilÖ

On the scorpion, the ball was more at home due to the increased length and units of the pattern. I started out using my Siege with a very similar drill with a laydown of 14 out to 10. When I threw the C-S in practice, I was 2 boards further inside due to more response at the end of the pattern. During transition, my Siege saw a little carrydown and started to deflect through the pins. I switched to my C-S and stayed with the same line in practice that I had found. I couldnít tell the carrydown was even there!

If you are looking for a ball for longer patterns and higher volumes that isnít sensitive to carrydown, then the C-System is for you. In talking with Chris Loschetter last week, he said that its ability to handle the carrydown seen on tour is why it is in the bags of so many of the free agents (including him). If this ball isnít in your bag, youíre missing out on a great product.

70 x 5" x 35
Pin above the fingers
No hole
2000 Abralon(haus)

I have been using this ball for a while, changing surfaces to experiment with the new coverstock. I am confident now that the 2000 finish suits my game the best. The 4000/4000 polish gave me too much skid/flip, and 1000 was way too aggressive.

The ball gets through the pins better with the surface adjustment. Don't be scared to tweak it if you think yours is not hitting hard enough. You do need some head oil. I've bowled in a few older houses with beat up synthetic lanes and the C System reads that extra friction too much.

It's a good benchmark ball to start your block with.

Placed the pin over my ring finger, MB at 45 deg.  This put the pin at 5 inches from my PAP.  I really wasn't sure what to expect from this one, tried it at out of the box surface to start.  I tried it at a fairly long house pattern.   I was very, very impressed.  It's kind of hard to equate this ball motion to anything else out there right now.  Through the heads, it really reminded me of the Absolute Inferno - one of the best Big B balls of all time. Super, super clean in the front.  The break point was very, very sharp.  But, what I typically see is that when balls now days take a turn that hard, they kind of straighten out.  This thing just keeps moving through the pin deck.

I brought it down to 2000 abralon to tame the brake point down a little.  I really love it at this surface. Just as clean in the front and a little more tame on the back.  The boys over at Big B have really hit a few home runs lately.  Keep them coming!

i laid out my c-system 4X4. i wanted a ball that would be strong yet controllable enough to start with on most of the houses we bowl at for high school season and i get more then i expected. i knocked the polish off and it turned out to be the strongest ball i've ever thrown im averaging close to 250 with on after about 11 games and i can use it all games of a series. this ball is deffinatly a winner. brunswick is finally puttin out good balls

New to Revaluations so be patient:

(my specs are in my profile)
Drilled this ball 5"x10degreesx5" which placed the pin below my ring finger.

I was looking for a ball that read the midlanes and still had something on the back end. My release mistakes are always to stay behind the ball and loose axis rotation which ultimately produces plaque 10's. So finding a ball that will let me get away with even some of these would be a benifit.

What I recieved was this and more. When I release this ball correctly the ball goes through the pins like nothing else I have thrown... it produce more entry angle and my ball actually hits the 8 pin sometimes. Thats a far cry from a strike where the ball goes staright through the pin deck entering on 17.5 and off the tail plank at 17.5. Sure I leave some 9's (LOL) but they are easier than 10's and alot more fun.

As for the issue with my relases, this ball somehow does not deflect as much in the pocket despite the ball rolling end over end into the pins. Some of the plaque 10's are gone. I think there might be something to this Salvino technology.

Brunswick C-System 2.5
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 1" below midline. Factory Sanded 4000.

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.

In one word "WOW". What a ball. It is her start with ball, her most confident ball in the bag. Numerous houses and different lines with this ball and the ball adjust beautifully to all of them. Gets through the fronts so clean, reacts so well on the back end part of the lane, reads the carry down very well. I am the most impressed with the cross alley spares, the ball does not over squirt going towards 4-7's and 6-10's. All styles will like this ball. I have not experimented with different surfaces with this ball due to how good the reaction is out of the box with this ball.

Bottom line, Mr. Salivno/Brunswick you have something very special with this ball. Actually has a better look on the lane then Storm's Virtual Gravity. More predictable but just as strong. Brunswick has really done their homework with this ball. This is one of those balls everyone has to try. Looking forward to future CS models.

Thanks for reading my review.

I'm an average bowler with a 157 avg, I went to the Pro shop in search of a new ball and the Pro shop owner recommend this ball for me. He drill it to have a strong break on the back end. I bought the ball on 11/11/2009 and I bowl with it the next night (11/12/2009) in my league. I bowl a 706 scratch series, with my games being 225, 237, and 244. I love this ball it great now. I never had a ball that do the things it does. I say BUY it.
Always Bowling,

Bought this ball 2 weeks ago. Drilled pin above ring finger, mb kicked out about an inch to the right of my thumb. I am a tweener with slow ball speed, averaging 200-210.
  First 2 weeks I tried to play deep and swing the ball, and had limited success,(nothing really bad, just nothing really good either). 6th set with this ball on a synthetic surface, I played this ball a little straighter (feet at 38, putting the ball around 13 at the arrows, and wow!!!! Threw 276,241,267, 784 set.
  This ball has the most drive out of any ball I have ever thrown. Once it hits the dry and turns, it just drives through the pins with little or no deflection at all. I would definitely recommend this ball to anyone who is looking for great carry.

Pin: Under middle finger
CG: 1 in from centerline
MB: 1 1/2 in to right of thumb.
X-hole: On VAL 3 1/2 ins down from PAP

Cover: Out of Box.

This ball has a motion that has been missing from brunswick's line. The cover/core allows the ball to push 1 to 2 feet futher than what you would expcet and the ball does not lose recovery at all. The recovery from the cover down the lane and to the right is a great aspect of this ball. Even with such a strong core, stronger layouts will not create a problem.

Strength: Cover, Cover and Cover.

Weakness: If I find one I will let everyone know.

I have used this ball on the PBA's Scorpion pattern on a surface that was harder than pro anvil. I was able to use the ball inside and out side. For me Scorpion can some times be difficult for my style when it comes to down the lane and to the right. This ball allows me a few extra boards to the right and angle error.

On the Kegal short pattern the Boardwalk I have room to the inside, that extra push from the cover/core allows me 4 to 5 board area on this pattern.

Brunswick is back!

After using my new Python for a couple of months and loving it, I finally got around to drilling up the C-system.

I drilled it 45 X 5 X 30 which put the pin above the ring finger about an inch and the MB about 2" left of my thumb (left handed). Weight hole 1" above my PAP and not into core. Another great piece from Brunswick. I can get in a bit more to the right with my feet and open up my launch angles with this ball as opposed to my Python which prefers a little straighter attack on the lanes. The recovery down lane with the C-system is impressive.

I will post more as I get to roll it on a few different patterns.
