Core aesthetics are nothing but marketing, if they just left the cores looking "normal," you'd have a bunch of bland looking geometry shapes that are just manipulated to get the numbers they're after.  So it's a lightbulb, don't care, the numbers are what matter.  The reaction is what makes it an HP3 line ball, not the way the core looks.  Very strong numbers for a lightbulb core, if you want to pay attention to what actually matters.

On the outside we find the brand new Ampedâ„¢ Pearl coverstock which will provide plenty of length yet yield plenty of responsiveness to friction down lane. Again not uncontrollable but it is definitely strong and that is what we were looking for in our testing process. If I had to compare this cover to something more recent, the Amped Pearl is closely comparable to the 73MHâ„¢ Pearl that was found on the Hyper Cell Skid.

So when the No Rules Pearl comes stateside it will be really interesting to see how it compares to the Hyper Cell Skid.
