What qualifies a ball as versatile ? It means you can use this piece of equipment and find a way to carry despite any change in ball surface, oil pattern, changes in axis rotation and/or tilt, angle of attack, ball speed, etc.
In this respect my Brunswick C-System 2.5 has been all I could ask for. I've used this ball dull, smoothsanded, and highly polished. I've thrown it on all the PBA patterns, typical house shots, the US open pattern, etc. I've used five different degrees of axis rotation. I've thrown this ball straight down the 1 board and as far left as the 25 board and every line in between. And the ball speed has been changed as necessary, anywhere from 14mph to just over 20mph.
For all these reasons I've already bought another 2.5 for the upcoming 2010-2011 season.
