I had my ball drilled with the pin down below the fingers.  (25 X 4 ½ X 70 )This provided me with a strong midlane roll and a very effective continuous, backend! This ball gives me the hooking power and reaction I need on the longer oil patterns.

The Nucleus core along with the Microbite technology coverstock gives me the look and the down lane reaction I am looking for. With this cover I don’t have to worry about the lanes getting burned up.  This ball gets through the head and maintains its power all night long. What a great addition to the Defiant line and my arsenal. 

The Hyper Cell, Asylum, and UpRoar provides me with everything I need to handle most conditions.

The Hyper Cell from Roto Grip is a bowling ball that I am going to drill a bunch of.  I have only thrown this ball for a few weeks and I have already ordered 2 more. I first used the ball in my sport league. We were bowling on the Women’s USBC National Pattern and I immediately noticed how much the ball hooked for me. Out of the box it I thought it reacted more then anything I ever owned before. I confirmed this fact 6 days later when I bowled on my house shot. That first night on the women’s pattern I couldn’t help but noticed how hard this ball hit the pins. I knew within a few frames that I really loved the Hyper Cell! I bowled next on the 37 foot Broadway pattern at NEBA. Once again I was covering more boards then I normally cover. The pattern was short, but I was still able to make the ball work and I made the cut. Next up was my house shot. This is a 42 foot pattern which the ball once again handled very well. The next night I bowled on the 45 foot Route 66 pattern which has stumped me a number of times, until last November, when I figured it out, and lead a NEBA Squad. That night the ball was absolutely incredible and I shot 996 for 4 games.  Two days later I used the ball at the Ferraro team tournament. I think the pattern was the Seoul Pattern. The Hyper cell once again handled the pattern quite well. The next day I bowled on Route 66 again in the People’s Tournament. I got off to a very slow start and was only 12 over after 2 games. I then shot 278 the third and final game to get to 90 over, and made the cut by 6 pins. I shot 234 my first match and lost my second match that day 247-244. The Hyper Cell did great in the high pressure tournament situation, especially since I needed every pin the last game.

Since I throw the ball fairly straight I really don’t get away with many shots that drag off the thumb, or one that I release a bit fast or thumb down.  The Hyper Cell has recovered for me many times in the past few weeks under these circumstances. When that happens for me it truly says a lot about the bowling ball.  I have also thrown a few out the window and missed right and couldn’t believed the ball recovered.

I convinced my partner Marcel Lessard to drill up the Hyper Cell. He drilled it and it sat in our office on his ball rack for a few weeks. I walked up to him before Wednesday night league, and basically told him you using your Hyper Cell tonight. He shot 816 that night which was his first three games with the ball. Marcel throws it even straighter then me, and the Hyper Cell opened up the pocket and lane for him also.

In short I have battle tested the Hyper Cell on a number of conditions. The ball is tournament tested as well. It is very strong and very versatile at the same time.  It is a special ball for me because it added aggressive hook to my bag which I usually don’t get. 
The Hyper Cell from Roto Grip is like buying hook in the box, and gets my highest rating without a doubt!

This Hyper Cell was drilled using my benchmark and favorite layout.  I had this layout on the Original Cell and decided not to change anything since I had so much success with that ball.  Out of the Box I decided to throw this ball on our Fresh house shot during league which is a 38 foot medium pattern. 

As expected this ball hooks a ton.  The best part about this ball is that it allows me to move as far left as I would like without losing its carry.  Many stronger (surface)balls begin to lose carry for me quickly as I being to move left on the house shot but the Hyper cell more than surprised in this department.  Even though this cover is very strong, it seems to resist burning up and has the ability to retain much more energy than other strong covers.  The ball hits like a truck with a very predictable shape.
 
Surface Change:  I decided to shine the ball up so that maybe it would allow me to throw the ball in league without having to put it up so soon.  This allowed the ball to clear the front part of the lane with ease and once it was ready to make a left turn, LOOK OUT.  Although it still retains its Hard Arc shape, the ball retained so much more energy that I was throwing pins everywhere. 

Sport Pattern:  This ball with box surface had absolutely no problems cutting through the oil on a variety of patterns.  I have thrown this ball on WTB Paris 47Ft and the 2014 National Team Patterns.  The ball allows me to attack the lane in a variety of ways.  I was able to miss right and have the ball make it back to the pocket when no one else bowling with me was. 
The Hyper Cell is one of the most versatile, Strong Asymmetric balls I have ever thrown.  It provides all of the hook you could ever need but doesn't suffer from burning up as quickly as some stronger balls do.  Another great thing about this ball is the 80H MicroBite Cover Stock.  I have Shined up, Sanded and repeated this many times on this ball. The cover takes all of these changes very well and after many games this ball still hits and moves as well as it did on day 1. 

If you're looking for a strong ball that you can actually use this is the one to get.!!
Here is my Hyper Cell Video so you can see how it compares to the original Cell.

The Hyper Cell is a combination of using the original Nucleus core that has an Rg of 2.52 and a differential of 0.056 with a PSA differential of 0.018 in 15lb balls; and the 80H Microbite cover that was on the Defiant, finished to 2000 grit abralon. The Hyper Cell really needs some oil in the front of the lane to get it moving in the correct direction with the box finish. A simple trip to the ball spinner for a coat of polish or a smoother surface will help if there isn’t enough oil on the lane to keep the Hyper Cell from slowing down too fast.
I choose to go with a 3¾ x6 ¼ x2 ½ layout to compliment the Asylum that I drilled up (4x6 ½ x2 ½). I wanted that true oil ball. I didn’t want a big backend reaction, and I didn’t want a ball that needed shined just to keep it from slowing down too fast even on oil. The 3 ¾” pin placement allows the ball to rev up, while the long PSA placement of 6 ¼” allows for a  longer transition in the hook phase of ball motion. Translation; I drilled for heavier, longer, slightly flatter from left to right patterns.  I used the Hyper Cell in a tournament that used the new 43 ft USBC team pattern. It was great on the fresh pattern. I kept my angles in front of me and moved in as the oil depleted.  I was then able to go to the Asylum as the pattern broke down in the front of the lane because of the righties moving left, into my lay down area. This ball would’ve been great had we bowled on the fresh for the match play portion, as I can see where it wanted to allow me to move in (15 minutes of practice with only a few people on the pair can tell you a lot), if there is oil to move into. A slight change of the hand position to create more downlane motion as the angles become steeper is really all that is required.
The Hyper Cell is a strong cover and strong core ball. It likes oil. I can see players having success with this ball at nationals this year. The only issue I can see for me personally is because of the long PSA drill angle, I can get a little too much over under on the typical Abe Lincoln top hat house condition. If I drilled another Hyper Cell for that, I would go with a shorter PSA to PAP angle, so that the transition of the hook phase is faster, and a longer pin distance from PAP as well, to reduce the overall board coverage and hook potential. If you need a heavy oil ball, give the Hyper Cell a try. With cover modifications, you can use it on medium volume patterns, but I would recommend a different ball like an Up Roar for medium-light to dry lanes.
Thank you for taking the time to read my review of the Roto Grip Hyper Cell.

The NEW Roto Grip Hyper Cell brings back the original Nucleus core, which is one of my all time favorite asym. weight blocks. I was extremely excited to drill this and give it a shot. I layed mine out with my normal asym drilling (60x4 1/8x30). I left the factory finish on mine and was extremely shocked that i was able to use it for a full session of 5 man league. The center that we bowl at and where i have my pro shop is notorious for EARLY HOOK, so its usually unheard of to be able to use a high performance asym ball for more then a game. The Hyper Cell is definitely one of the cleanest asym balls I have ever thrown, and doesnt burn up after a game and a half like other asym balls are known to do. You will not be disappointed in this beast of a ball. Own It!

Looking for something with some surface that would keep it’s energy and allow me a different option on the tougher stuff. Ball accomplishes that. The layout is meant to get the ball down the lane but try and simulate the heavy roll. Does just that.

40 ft house pattern – Wood pattern with medium volume. More useful than I thought. Ball really does clear the fronts and stores energy. Is a very good option to create heavy down lane roll that won’t over read. Did run out of lane late.

Kegel Autobahn – It’s a medium difficult pattern. The surface really helped but the layout made the ball a bit weak in the back. On a pattern that requires some early roll, the ball didn’t have enough early. This is layout specific though.

Nationals doubles/singles – One of the more difficult patterns. On the surface I was on this ball was a big help. Didn’t over read the end of the pattern which was big for me. Also, it cleared the temptation to roll early and over react in the heads. This is where the ball was most useful.

Overall, ball does what I want it to do. With the layout it has some limitations that a heavy surface ball with that type of layout would expect. It’s a useful curveball for me.
