Radical Katana Assault Bowling Ball Features:
The Katana Assault has an RG of 2.501, a differential of 0.051, and an intermediate differential of 0.020. This core yields a quick response to friction and a lot of continuation through the pins. The Katana Assault and the new chemical compound cover known as HK22 Pearl create a new level of backend reaction. This is a Katana on steroids. A monster flip ball, a motion the industry has always craved and now we have brought it to a whole new level.

Once again putting the HK22 Pearl cover on a Radical piece has raised the bar in expectations. I drilled mine pin down as I wanted to add an asymmetrical pearl to my pin down bag. I have only had the control given by the pin down layout in the Max Results. This ball is exactly as expected smooth and strong through the pins. The HK22 cover gives that special punch on the back and carries the slight misses much like the Bigfooot Hybrid. Love this one and I will be getting another for a pin up layout!

The Katana Assault is going to be one of the strongest pearls ever made. They took the katana core and added a giant flip block at the bottom. The cover is a pearl reactive with the HK 22.
I drilled mine 50×4.5×40.
With this layout the ball easily gets through the front of the lane that’s absolute hook monster on the back end it doesn’t die out and gives you that great continuous finish through the pins. This ball is a must have in your bag.

I loved my original Katana. Now with the new HK22 cover, it is back, and better than ever. Being a Hybrid, it fills a gap between my Top Speed and my Black Widow Ghost. This ball fits perfectly in my arsenal.
