This is my 1st review on here so please take it easy on me.

Mutant Cell Pearl
15# 3oz, 2-3" Pin, 2.80 oz top weight to start.

Layout
5" x 4" with 2 1/2" pin buffer
This put the pin almost directly above my bridge by about 3/4", the CG about a 1/2" above my mid-line and the MB to the right of my thumb about 1.5". No weight hole for this one.

I drilled this similar to a Cell Pearl I have, 5 1/2 x 4, but I wanted the Mutant Cell Pearl to pick up just a touch sooner and finish stronger.

First time I used it was in my buddies Vegas league (subbed only to throw this ball...LOL). The house shot is used for this league, 40' of China. For the 1st game and part of the 2nd it was OK but not great. A little too much backend and left a couple 9-pins and 10's for 236. 2nd game it started rolling better as the oil pushed down, and had 258. Game I started X 9/(10 pin) moved in and went sheet for 280. I definitely like this ball when there is some oil down lane, handles carry down much better than my Cell Pearl.

2nd time I used this rock was in my open doubles "sport shot" league. We use the Kegel sport patterns. This round we are on Boardwalk, basically Kegel's version of Cheetah. Honestly I didn't think there was anyway possible I would use this ball on this pattern but I brought it cuz it was new. We bowl 6 games, moving after every 2 games. For the 1st set I used a Rogue Cell that I pretty much drilled for these type patterns (pukes hard on the backend). Nothing incredible, shot like 440ish. 2nd set the lanes were scorched, I stayed with the Rogue and just threw it harder. Shot like 430ish. In our 3rd set the lanes were pretty tight, especially down lane. Enter...Mutant Cell Pearl, I was able to bump in just a touch and go like 10-12 at the arrows to like 2-3 at the break point. Amazing how well this ball rolled, it stayed smooth and on line but gave me plenty of pop to avoid flat 10's. I shot 258, 237 the last 2 games using this ball. Wish I could have switched to it sooner.

I am really looking forward to throwing this ball on some longer patterns and I expect to use it a ton, in the middle and late in qualifying blocks.

From what I have seen so far, Rotogrip has produced another winner!
