The Rattler NU takes advantage of the new chemistry in cover stocks Not Urethane (NU). This
chemistry allows us to create a unique urethane motion without the pitfalls of a urethane ball.
The Rattler NU features the original Rattler core with an RG of 2.48 and a differential of .035,
giving you a medium diff core and a unique cover. The Rattler NU is a great addition to the
Rattler lineup, yielding a smooth, controllable, continuous ball motion that allows you to control
the back end of the lane.
