Ever wonder what would happen if you took the dominant traits of proven cores and mixed and mashed them all together? Well then look no further. We took differential stability throughout the lane, consistent axis migration and defined RG bands to create our most dynamic and continuous core to date. Can you say dynamic? I knew you could.

The idea behind the new Amped™ Pearl coverstock was to formulate a structurally stronger and more pliable pearl material in order create our most skid/snap reaction to date. You are welcome!

The No Rules Pearl comes out of the box with a 1500-grit factory polished finish in order to provide a completely different reaction from the No Rules™ solid sanded version. The No Rules Pearl is ideal for those Medium to Medium/ Heavy oil conditions. Like all pearls it can be sanded to battle a little more oil or just to blend out the reaction at the breakpoint.
