Its a pretty consistent, hard arcing ball. It works well on many conditions, for every type of bowler. Funny, it kinda reminds me of my dull urethane blue hammer, but harder backend. Overall I think Hank & Roger have  something special here. I would reccomend this ball to any bowler.

I had plenty of high expectations for my Cell. I must say I was not disappointed. My game is in the high tweener range with rpms running around 360 and ball speed around 17 mph. In looking for a ball for heavy volumes and/or longer patterns, I usually look for strong coverstocks with lower RGs and fairly high differentials and adjust the surface as needed; the Cell certainly fit that description.
With its out of the box finish, I was not expecting to get a decent look on a typical house shot, but since it was what after I drilled it up, I thought what the heck and what happened was not what I expected. I moved almost an arrow inside the oil line and kept it tight in the oil. The Cell easily pushed down the land and hit with what can only be desribed as explosive hit. After 10 shots I had not lost a hit. I I began to move further and further inside to see how much room I could create and found I virtually had the entire lane. It was amazing to see how much room the Cell created as wall as the hit the Cell produced. The ball was so impressive I had people gathering around to ask what type of ball I was throwing.
While very, very impressed, I was a little concerned about the performance of the Cell on a true heavy volume pattern/ and or long pattern. I figured if the ball looked this good on a house shot, it may not be a true oil ball. Well, I need not have worried.
At a center that featured a 42 foot Sport-compliant pattern, where everyone was struggling. I pulled out the Cell and it dug into the oil early and gave me a very controllable srong move off the back of the pattern without overhitting the backends. The Cell allowed me to create a little room wide of my target that others simply did not have.
This ball is a must in any serious tournaments bowlers bag and those that dont have a Cell are giving away pins to the those that do. The Cell is the must have ball of 2008.

I am a Senior bowler, age 68.  My book is around 215 and I am averaging well over 220 in the month I have been using the CELL.  It hooks more than any ball I have ever used and hits very hard.  I leave a lot fewer 10 pins because of the strong back end.  I would recommend this ball to everyone.  NorbT

Ok, im gonna be honest here. I heard so many good reviews about this ball, I had to buy it. I am a high rev, high speed bowler. When there is alot of oil on the lanes, I usually cant find a ball to move that well, unless I slow down the speed. So i decided to purchase the cell.

I got this ball drilled to just hook, I wanted the ball to read a little early and just flat out hook. I found that when I bowled it on oil and I wanted to swing the lane. It just rolls out. I hated the ball. But then I decided to keep the speed and revs up, yet throw a more direct line. WOW. This ball is a beast. I through about 11 games over 250 in a month, and ive shot 289,279,and a 300 in 24 hours. This ball is phenominal. It just hits so hard. Carrys everything.

Im glad I played around with it. It just seems like a ball ment for everyone. At first I assumed it was for low rev slow speed bowlers. But this ball is extreamly versitle, and I recommend to anyone. Roto Grip, just might have a ball to take Ebonite down with =)

I wanted to wait a little while before I wrote my review on the Cell.  When I first got it about two months ago I layed it out specifically for the U.S. Open.  Not only did that layout fail for that tournament, but I was unable to get the ball to work on any pattern in a consistent manner.  I was beginning to think that it might not be as good a ball as everyone had told me...then I got another Cell and used a different drill pattern.  This ball is absolutely amazing and is not only the best ball in my bag, but maybe the best ball I've ever thrown my entire life.  I started two Summer PBA leagues a week ago on Monday and Tuesday nights.  I've now bowled 12 games in those leagues all on the Shark pattern, here are my three sets (4 games): 931, 929, 1000.
I used the Cell for all of these sets and am averaging close to 240, well above anybody else bowling in either of the leagues.  I've had some huge games in these sets too, including 280, 275, and 267, I also almost shot 800 last night (785).  Many people that are bowling the league are saying that I'm making the shot look easy, and that is due in large part to the Cell.  If you don't have one, get one.  If you do have one, get another one.  This is the best ball on the market and it is sure to transform your game.

ROTO GRIP - King Of Them All!

I have been a hammer fan for along time. Once I saw the reviews on the Cell and in person. I bought the Cell to try it out.
I bought 15lb Cell and drilled it 4"pin 60 degree angle. I throw the ball around the third arrow which is the 15 board. The ball reacts well for me. I like the how the cell has Improved my game alot. In the last week on two of my leagues I bowled 200+ games and was amazed at how well the ball was for me. I never thought that Roto Grip would have a ball that would ever get me to change from a Hammer ball. I was wrong about Roto Grip. Now I can say that Roto Grip has me going away from Hammer. Roto Grip Cell is the best ball on the market today. I also bought the Pluto to compliment the Cell as a second ball. I have found the two balls to be the best two ball combo that I have ever bought. I would recommend the Cell to any one but a beginner bowler. Roto Grip is the King of then all!!!!!!!!!!!!!!!!!!!!!!

I got my Cell a few months ago per my driller's recommendation.
Bowler info: Pap is 5 1/2 over and 1/2 up, ball speed is 18-19 mph, 275-300 rpm, axis tilt is very low (less than 10 degrees), axis rotation around 20 degrees

Drilled up 5x3, MB at 45 degrees, pin buffer is around 2 inches

I've tried this ball on multiple surfaces and oil patterns.

I started off with Box Finish (2000 grit) and decided to take it up, because I had to adjust every shot because of how much oil this ball burns up. On a house shot I had to play inside of 20 to get the ball to the pocket and not past headpin.
The ball at OOB was very smooth off of the break dispite how flippy the drill I have on my Cell is.
This ball is very strong on a THS and will easily handle most THS's with extra speed and an ultra inside line.

With my revs, I brought up the surface though to 2000 polished, and threw it, it was still very smooth off of the spot, just with a touch of added length, although polish made the ball read not as well, so I brought the ball up to 4000 and polished it, just to test because I dont face too much oil. I didnt like it too much at this surface and the shot really turned into a hockey stick shape and the carry improved.

I'm going back to 4000 polished once my NM gets here, just because of the added carry, and how much more controllable it is on a THS.

I'm using it at 4000 right now and I love it though. On a THS it goes fairly long and is smooth off of the spot, and more of a medium-heavy ball allowing it to be used all night.

I've tested this ball on Two PBA shots as well.

Scorpion
Well, this pattern is 41 feet long and a heavier shot, so most people use lots of surface, but I kept the Cell at 4000 and loved it.

I could play deep inside with the Cell around 20 and out to 13, or I could play from 15 to 7, or I could throw the outside down and in lines.
The Cell really allows the Scorpion to be molded to how you want to play, this ball is probably my favorite look on this shot.

Viper
Viper is 37 feet long and a much harder pattern to score on.

With the Cell at 4000 I found two lines, I could play inside (but if you miss a board left it goes to the 7 pin) or I could play down 10 and have the ball hold, then hit.


Overall, the Cell is a very versatile piece of equipment that should be in everyone's bag and it handles surface change well.
Any questions? PM me.
