Because variety is the spice of life, a solid shiny cover is something we have not done on an asymmetric ball in a really long time. The idea here was to again expand the HP4™ line with yet another new reaction. This beauty is ideal for those medium type conditions and will dominate friction quite well. Although if need be, this ball can be sanded to take on a lil slicker condition.

The Nucleus core is time tested and proves the point that if it isn’t broke, don’t try and fix it. Most recently found in the Hyper Cell Skid™ and Hyper Cell™, this asymmetrical part creates the balance and control typically seen in a symmetrical part, yet gives you the pop through the pins as expected from an asymmetric.

The 75M™ Solid reactive coverstock has been formulated to provide an even more stable reaction in the HP4™ lineup of balls. Because sometimes strong is not always needed. We opted for control in a different form by taming down the shell just a pinch. You are welcome.

My 75M™ Solid Reactive Cover has been tamed just enough to make me more nimble than my relatives, but I’m just as dangerous.

Nucleus Core
Roto Grip Nucleus Core

The Nucleus Core is hands down the most versatile asymmetrical core design ever created in the history of forever. First seen in the original Cell back in the day, this part has withstood the test of time and still performs better than most. No matter how it is drilled, no matter the rev rate, no matter the ball speed, this core always gets into motion and stays in motion all the way through the pin deck.
