What I Was Looking For In This Ball Layout:
I did some early testing of this ball with Brunswick and was excited for it to come out for many reasons. The reason I was most looking forward to this release is that it will be the first C System ball to feature a symmetrical core.

I love the asymmetrical world we have become accustomed to but sometimes a good symmetrical/reactive resin ball is just what the doctor ordered.

I was drilled this one difference then the early test balls because based on what I saw I felt this layout would be neutral enough to let the ball motion speak for itself. I expected this ball to handle the lane well and make a strong but predictable move on the backend of the lane.

The vision in my head was a old Danger Zone I had that was drilled identical to this.

What I Ended Up With in the Ball and Layout:
Oh joy, this ball was so perfect for me. I love when a ball just rolls good from the first shot you throw it. The C System 4.5 reacted just how you would think a high performance symmetrical reactive ball would...GOOD!

From the first shot I threw on the fresh oil to the last after 2 1/2 hours of bowling the ball reacted the same and my moves on the lane were minimal. Oh those were the days when I did not have to move entire dots at a time and end
up sliding in the left gutter.

Don't get me wrong this ball still hooked quite a bit but there is something different about it. The ball got through the heads with ease and transitioned into the middle part of the lane well. The ball seemed to rev up nicely off the friction down lane and made a very strong move towards the pocket. The ball had enough energy to continue through the pin deck perfectly and it hit as hard as anything else out there.

Compared to the previous balls in this line it falls in between for me. Brunswick is going to better explain their numbering system with this release so we all understand it better. Even though this may not hook as much as your 3.5 you need to give this ball a try and I think you will agree with me that it is a really good piece of equipment.
