Ball specs – 15 lbs 3 oz, 2.82 oz top weight, and a 3 3/8-inch pin.

The Mutant Cell Pearl was punched using the dual angle layout method, 5-inch pin by 40-degree drill angle by 30 degree VAL angle. If you are using the Storm method, the layout is a 5-inch pin, 3 ½-inch mass bias, and a 2-inch pin buffer. (Looking for a little length with a strong backend move.) An X-hole was not needed and the finish was left OOB.

For comparison sake I threw the Mutant Cell Pearl and a Cell Pearl. The Mutant Pearl provided just a little more length; about the same read in the mid-lane and a very different look on the back end than the Cell Pearl. I would describe the backend move as stronger off the friction with more continuation through the pins. Another way to describe the back end motion is very strong but not unpredictable. Both hit and carry were tremendous. This one is a keeper.

The Mutant Cell Pearl will handle oilier to medium heavy oil patterns and provides a ball motion that many, many bowlers will want in their bag.
