Ball Name - C System 4.5

Bowler Specs
Right Handed
Tweener
15 MPH
Out of the Box Surface
Axis 5 3/4 over, 3/16 up

Description - The C System 4.5 combines a symmetrical weight block with  Chemical Friction Technology to produces a quick response and improved back end reaction.

Drilling - Pin 5 inches and below the fingers with weight hole on VAL.

Reaction - This ball is just as clean thru the front as the 2.5 but definitely quicker off the spot.  FOR ME, if I played the gutter the ball stood up and rolled or if I played the whole lane, the ball consistently made it back to the pocket with authority.  If you run into a condition where the 2.5 is going by the break and 3.5 is checking up, this is the ball to pick up for sure.

Overall - The C System 4.5 will be a welcome addition to your C System Collection.

Thank you to Billy O, rep Brian Bever and all the good guys at Brunswick.

The latest addition to the Chemical Friction Technology balls is the C System 4.5. The C System 4.5 cover has a lower friction factor than the 3.5 which allows it to generate more length through the heads and mid-lane without giving up the quick response and strong traction on the back-end. The 4.5 is powered by the new I–Block symmetric core which is a modification of the the original asymmetric I–Block core. Brunswick created an asymmetric base with an asymmetric flip block on perpendicular axis. The two asymmetrical pieces work together making the core shape symmetric. The core was thinned down and stretched to raise the min RG but maintain a strong differential.

I drilled my 4.5 with a dual angle of 55X5X35 so that I could create good length and a strong move to the pocket. What I got was awesome. This ball was clean through the front and mid part of the lane but had a very quick response at the end of the pattern. This ball allowed me to keep my moves minimal during the night and never lost its strong backend move.. I must say this piece has a great ball motion with plenty of pop down lane and tremendous carry. Congrats to Brunswick for another great ball.

The C System v4.5 is just what the doctor ordered for those Brunswick users looking for a ball to clear the front part of the lane.  In years past the bowling public has perceived brunswick balls to struggle getting down the lane, creating area on the friction, and carrying the rack when being thown away from the pocket.  This Pro Performance release is Brunswick's answer to these bowling situations and more!  Billy O and the R&D guys have a boneified homerun here.  This ball does everything our competitors balls are supposed to do well and combines it with the already documented C System length and pin carry.  On our 40 foot house shot the ball is long and super strong, allowing me to play almost any area with speed changes, hand adjustments and ball surface adjustments.  I threw this on our PBA experience Cheetah pattern, which was very tight on the corners for some reason, and I had several more boards of area when compared to the other bowlers around me in the bowling center.  I ended up shooting 671 the week after shooting 555 the week before because I couldn't open up the lane.  The C System is the cleanest rolling Brunswick ball I have ever thrown.  I did most of my testing with the rough buff surface but don't let that fool you, this ball is super adjustable.  If you need more grip, simply scuff with 2000 siaair and watch this ball come to life.  Watching this ball go down the lane it reminds me of one of those past balls of the year from our competitors and it is simply unstoppable. The C System v4.5 is the reaction Brunswick fans have been waiting for.  If you are looking for easy length, strong reaction, and predictable power on the breakdown look no further, the C System v4.5 is the answer!

C System v4.5

Layout: 65x5x35, no hole

Ball Speed: ~20 mph

Rev Rate: 400

I was really excited about this ball once it was announced. I was a huge fan of the first two C-Systems, so I was anxious to try this one out. It did not disappoint at all. On a typical house shot on Brunswick Anvilane, this ball got great length and even better backends. Throwing it side by side with my pin up 2.5, this ball got an easy 2 to 3 feet more length, and had a lot better entry angle when playing a deeper inside line. It’s transition off the friction was much faster, but still predictable, maintaining that hard, yet smooth arc on the backend we get with the C-System line. For me, the v4.5 was 3 and 2 stronger than my 2.5 on this particular condition.

All in all, this is a great addition to the line, and personally, I’ve always had good success with symmetrical weight blocks, so I believe the new symmetrical version of the I-block core will be very “user-friendly” to the average bowler. So, if you are in the market for an all-around “useable” ball, the v4.5 is it!

There is one word to describe this ball... WOW. This ball is very clean through the fronts and really responds to the friction.

Ball 1 was drilled 50x5x30. I wanted this one for when the lanes break down and I need that ball that just comes off the spot. That is what this ball will do without any problem. It is cleaner than both previous C Systems releases.

Ball 2 is drilled 50x5x80 with a P2 hole. I wanted this one for when I needed a ball to get through the fronts and read the midlane and have that pop still down lane. This drilling is about 4 and 2 stronger than the pin up drilling. The best part about this ball is it still clears the front really well.  Most of the time when I drill a ball with the pin real low it will not save energy for down lane but this one does.

When needing a ball that clears the fronts and comes off the spot this is the ball you are looking for. Players with higher ball speeds or lower rev rates may need to add surface to this ball. As with the previous C Systems this one takes surface changes very well.

Ball: Brunswick C-(System) v4.5

Layout:

Pin 5” from PAP, above ring finger
CG ¾” above and ¾” to right of grip center
No XH

Initial Surface Preparation:

Box finish

Purpose:

To give me an option for broken-down tournament conditions where I need to be able to count on recovery when I give the ball some room to the outside.  I’ve been using the Python on conditions like this, but I’ve found it to be touchy at times because of its sensitivity to oil.

Why this ball?

The C-(System) v4.5 is intended to have a lower overall friction factor than the C-(System) 3.5, with good length through the heads and midlane, but a fast response in back and a more dramatic change of direction than the C-(System) 2.5.

Observations:

The C-(System) v4.5 came with a 3 ½” pin, so I went with my “favorite” symmetrical layout, with the pin 5” from PAP, above the fingers.

The first time I threw the v4.5 was on a fresher house condition with quite a bit of help in the middle and down the lane.  I aligned myself to get the ball to touch more of the dry, and I saw the strong move off of friction to which I’ve become accustomed with the CFT covers.  In fact, I had to cheat left with my feet to compensate for just how strong of a bounce I was getting from the dry boards.  Using this alignment, I had a good reaction with the v4.5, with the same great look at the pin deck that I have with the C-(S) 3.5.

When I threw the C-(System) v4.5 on a higher-friction lane surface with a house-type condition that was undergoing some transition, I saw the ball really begin to live up to its potential.  I had to open up my angles on this condition to avoid hitting the push down lane, but the C-(S) v4.5 never backed down from the challenge of recovering.  With the power came a price, though  playing that close to the lane with a ball so strong off friction resulted in me having to make frequent moves in order to keep the ball off of the headpin.  Eventually I did reach a point where I was far enough left so that I wasn’t hitting the house track area until further down the lane, and I didn’t have to move nearly as often.  From there, I was still getting a nice clean reaction in front and a strong move at the break, and I had little difficulty getting the corners out.
 
Conclusions:

I know the question that I will be asked the most about this ball is how it compares to the C-(System) 2.5.  The overall hook is about the same, but the reaction shapes are noticeably different.  The 2.5 has the right combination of midlane read and strength in back to make a choppy condition play like a blended shot, but on a more favorable condition, I sometimes find it tricky to control the breakpoint.  The v4.5 doesn’t read the lane nearly as early, but for me, it has been even stronger than the 2.5 when it does hit the friction.

I could easily envision carrying all three CFT balls as part of a tournament arsenal.  The C-(System) 3.5 would be the first ball out of the bag for the fresh.  If the transition progresses in parallel lines, I could switch to the C-(S) v4.5, move left, and use the dry to get recovery.  If the condition transitions unevenly, I would go to the C-(S) 2.5.

I found this ball to be impossible not to throw. I drilled the first one which had a 4-6 pin with the pin up which gives me a high pin but very controllable and predictable. The second one has a 1-2 pin so I had that one rico'd. Both balls are really good and my pin over is by far the cleanest ball through the front of the lane, it has great movement off the spot and I throw it more than any other ball.
