5"x3"x2.5"

I have been dreaming of getting a "Virtual Gravity" type reaction (long and strong on med-heavy) and was actually pretty nervous about the initial reports- "makes the VG look like plastic.."

I am very pleased with the reaction, gets longer down the lane than the original Cell, more pickup on the back than both the Cell Pearl or Rogue.  It also seems that the ball motion allows for more area/mistake room.

Should have a video posted soon.

Mutant Cell Review by Cory Rockteschel, Roto Grip Amateur Staff Member.

   PAP – 5” right
   Span – Middle finger (MF) 4.5”, ring finger (RF) 4.625”
   Pitches – MF .375 left 0 rev, RF .375 right 0 rev, thumb .125 left .375 rev

Review:
   I drilled 2 Mutant Cells.  I drilled them to give me 2 different looks at the pocket.

Mutant Cell #1: 4x4x3.5 with a 29/32 weight hole 5” right
   This ball was a monster right out of the box.  The day that I drilled it I bowled our PBA league, on Scorpion, and shot a 657 with it playing the lanes 23 to 8.  After that I bowled our scratch league and had 30 out of 36 strikes for an 802.  I drilled the ball to give me a more even roll to give me some predictability on the lane and that is what I got.  What I did not expect was how much the ball actually moved on the lane.  Our scratch league used a 41’ pattern and I was standing very similar to what I was on the Scorpion.  I was bowling   20 to 6 and the ball was shredding the pins.  I only left 2 multi pin spares to shoot at and both were because I got a little slow with my speed.  This ball will be a staple in my arsenal for a long time.

Mutant Cell #2: 4½ x 3½ x 1½ with a 53/64 weight hole 5” right
   This ball is very similar to the other except for the entry angle.  This Mutant makes the turn off of the spot much quicker than the other.  I was throwing both balls during a practice session of mine to get a feel of the differences.  Both balls covered the same number of boards but #2 went a few feet longer and made the corner a little faster.  I expect that this ball will be my go to ball for most heavy oil situations.  I was also experiencing the need to be a little more consistent with my speed.  

You can look at these balls on video and others at: http://www.tenpincoaching.com/Roto_Grip_News.html

No matter how you drill yours, you will love this ball for use on heavy oiled lanes.  Roto Grip has another hit in this line of bowling balls.

My Axis is 5 5/8 right, ¼ up, my speed is average and I would consider myself with higher revs but more up the back.  So not a cranker but not really straight either.  

I drilled this ball strong, pin and mass bias 4” from PAP, box finish (no extra hole).  This ball is as strong as I’ve had in a very long time.  On a house shot I can get as deep as I want and it still wants to come back from anywhere with no quit.  On oilier patterns this ball rolls very good as it still will turn when most others just skid.  I also have had some success playing the tighter Kegel patterns if I stay behind the ball and try to roll it straight.  With this release I can get it to roll out.  However, if I am not trying to release it up the back the ball finishes way stronger than I would have expected even without polish.  This is a fantastic ball for oilier conditions or for those who need more help keeping up with the crankers.

I drilled 2 Mutant Cells and so far have been very please with the reactions. The first one is a 4 1/2" pin from pap below my middle finger (pap is 4 over and 1/8 up)the rg is 3" from my pap with a small low hole. I left this ball with the out of box finish and it is very strong...reads the midlane very well and has great continuation down lane. I've never had a pin under ball finish so well. I used it on a 44' sport pattern and was able to open up lane...best line was 17 to 10 with good recovery. On typical house shot its just stand right throw left with virtually no out of bounds but wouldnt be my choice for house shots just too strong.

The 2nd Mutant I drill with a 6" pin from pap with the mass bias above my thumb which put it as 4" from my pap I also hit this ball with Storm step 3 compound just to take the roughness off. This ball is very good for clearing the heads and reading the late midlane with a smooth even reaction at the break point. Should be a very good ball for me when needing to play the track or when seeing drier lanes. All in all this ball for me is like a regular Cell with more length and more pop down lane....should be a very good seller for Roto-Grip.

The Mutant Cell is the strongest of the line to date.  This ball has about 3-5 more boards hook than the original cell. This ball has a great move in the mid lane and a continuous strong back end.  I had mine drilled with the pin next to the fingers with the mass bias to the right of the thumb and a weight hole.

This is a great ball for medium to heavy oil.

This is the first ball I’ve had that people are coming to my lane and taking it to use during league play.

This ball plays best for me if there is some oil in the heads to get through the front of the lane.

WOW is the first thing that came to mind after drilling this up. Drilled it 35 x 4 x 35 and amazed at how easily it gets to the mid-lane but unlike the original Cell this one has a strong finish. Bowling on a THP but since they are Pro Lanes it's always like an automatic out of bounds and I had yet to find a surface that would recover until the Mutant Cell. This ball comes back from anywhere and carries better than any ball I have ever thrown.
 
I am just a stroker but with the Mutant Cell I get a power player look with messengers on every shot, this ball was turning heads from 6+ lanes over. I am 221 on the house pattern and this ball gives me an extra 30 pins a game from carry alone.


Nice job RotoGrip, and great design Hank Boomershine!

This ball is a must have in the bag for everybody. I have never seen a ball perform like this with the great roll and continuation through the pins it has. Normally this type of ball would not have a drive through the pins when you get close to the fourth arrow and play out to the fourth or fifth board but it does. Even when you just roll the ball and want to play straight with it, the continuation is still there. This ball is just amazing.
My layout on this ball is a dual angle 30x5x40 and the hole on the axis is ¾ with the pin 5 inches from axis. 3 inch pin buffer.  MB 2.5 from axis 1 inch inside val. (high gloss finish)

The Mutant Cell has been a great addition to my arsenal.  I am currently bowling in a PBA experience league and was able to throw my new Mutant on the shark pattern.  I was happy to find that the ball had a great reaction and carry.  I am a lower revs player so this ball definitely fits my game on the longer pattern.  I also was able to throw it on a house shot without it overreacting or rolling out.  This ball is a versatile piece of equipment that every bowler should have in their bag.
