The No Rules Pearl is the follow up pearlized version of the No Rules in the HP4 line of balls from Roto Grip. The pearl cover called Amped has an attractive onyx/neon green/silver color combination and is finished to a 1500 grit polish. This cover change from the micro DNA on the solid, creates a reaction more suited for medium oiled lane conditions. The No Rules pearl uses the same Chaotic core found in the solid version, which has an RG of 2.51, a differential of .053, and an intermediate differential of 0.018, in 15lb bowling balls.
I drilled the No Rules Pearl 4 x 5 ¾ x 2 ¾. I choose this layout mainly to maximize mistake room and generate a large amount of flare when bowling on high scoring league conditions. The first time using the ball subbing on a 39 foot high scoring house pattern, I shot games of 300, 245, 300 for 845. I would say that I succeeded in picking the proper layout for the conditions and ball. The No Rules pearl gives me good length, with a controllable change of direction at the breakpoint. Comparing the No Rules pearl to my Dare Devil (both balls using the new Amped cover) with a layout of 4 ¾ x 5 ¼ x 2 ½ on the Dare Devil; the No Rules has a slightly later read of the midlane, and has a more defined change of direction, and roll toward the pocket than the Dare Devil. As I remember some of the shapes that some older equipment made throughout the years, the No Rules pearl reminds me most of my Gravity Shift, in that both balls seemed to be easy to get through the heads and to the breakpoint, but didn’t over react once hitting the dry part of the lane, as sometimes pearl balls do for me. I’ve used the No Rules Pearl on a few different house patterns so far, all with good success. I seem to be able to chase the pattern in on the lane, as the oil breaks down, or go a little straighter and bump the wall on tighter typical league conditions.
I really like the combination of cover and core with the No Rules pearl. Also, Roto Grip is really on to something with this pearl Amped cover, as both the No Rules pearl and the Dare Devil rolls great for me. Thank you for taking the time to read my review of the No Rules pearl by Roto Grip.
