Introducing the Nuclear Cell, the newest release in the HP4 line. The Nuclear Cell uses the popular Nucleus Core wrapped with the new eTrax-P20 cover. The layout that I went with was 4 1/2 x 4 1/2 x 3, this layout put the pin in my ring finger.  You have the strong and heavier rolling core wrapped with the clean and very responsive cover and that just makes for an absolutely fantastic combination! This ball matches up really well on medium-heavy conditions and allows you to move in even on the drier stuff. If you are looking for a strong ball that has great back-end, this is the ball for you!

OMG, can you say HOOK!  The latest addition to the Cell line, the Nuclear Cell, will not disappoint those looking for a strong asymmetrical pearl.  No matter really how you drill this ball, it comes out firing on all cylinders.  For a pearl this ball opens up the lane and just when you think you have lost it to the right, it helps you out by flying back to the pocket. The Nuclear Cell will be a perfect step down ball off either a solid asymmetrical or stronger symmetrical when the lanes initially transition and a strong core yet clean cover is needed. I have personally found this ball to be a perfect gap filler in my arsenal on sport patterns for many reasons. It fits in nicely between the stronger solids and weaker pearls that will be used early on in squad blocks that will give the proper shape when those stronger solids are too early and the weaker pearls are not enough to turn the corner.  I have drilled mine 60 x 3.75 x 25, which is my strong drilling, and it does not disappoint.  I am going to drill another one 45 x 5 x 55 to compliment it for playing more outside.  This is a ball you may want more then one, its just that good!!

The new Nuclear Cell From Roto Grip features the powerful Nucleus core wrapped in eTrax-P20 Pearl Reactive cover. The result of this combination is one of the most responsive balls ever made.

I tested the Nuclear cell on a fresh house shot that had very clean back-ends. It was so strong off the friction that I had to throw the ball much more left to right compared to anything else I tried. It was probably not the best choice on the fresh because If I got slow or didn't create enough angle through the front it was too much in the back-end and I was sure to leave a nasty split. But as I moved left it just got better. This ball is so dynamic off the end of the pattern that once I was left of 3rd arrow it felt like it was impossible to miss right.

The next day I came in to see how it would react on the fill shot. The back-ends are always very tight, and I knew the Nuclear Cell would be perfect for the condition where other balls had trouble finishing. I had to get the ball a little farther out on the lane when I tried to play near the friction, but had no issues getting it to come off. I moved in to where I would normally play and was happy to see the ball still picking up down-lane. When I moved inside even further it really shined, a good release and the Nuclear cell would get back from almost anywhere and it's carry is exceptional when covering boards. This ball is just down-right strong off the spot. So much so that it takes away a ton of the over-under you see with pearl equipment, because there's never really 'Under'.

The newest Cell cored bowling ball is the Nuclear Cell. With the same Nucleus core that has been in every Cell ball so far. With a RG of 2.52, diff .056, and an Intermediate diff of .018. The nucleus core is wrapped in the new eTrax-P20 which handles heavier oil while also creating more down lane motion than the eTrax-P18 cover on the halo pearl.
The Nuclear cell is much more angular than its predecessor the Hyper Cell Fused. Not just because of it being a pearl cover stock whereas the Fused was a Hybrid but also the new formulation of the cover stock makes it cleaner through the fronts and more angular off the spot. As I do with most polished bowling balls, I took the shine off of it after throwing it a few times. 3000 Grit Abralon seems to work the best for me while it still allows it to be clean through the front it is smoother off the spot without the polish.
For me this ball is a house shot killer, most house bowlers will benefit from the easy length and backend that this ball offers. It is another ball for the medium sport shot patters or later in the block when the ufo starts to become to much ball but the wild streak is not in play yet.

The New Roto-Grip Nuclear Cell brings back that shape that we’ve all come to love from the Nucleus core. With the eTrax-P20 Pearl coverstock, this thing is a monster on the lanes. The Angularity and strength down-lane is unreal. I used a 4” pin to pap with a 2” pin buffer. I can honestly not say enough great things about this ball. It allows me to play any part of the Lane with ease.  Even when I move right and take some hand out of the ball, it sets up and still hits like a train. This is a most have ball and is currently my favorite ball in my bag.

The new Roto Grip ball in the HP4 line is the Nuclear Cell.  Let's just say I'm a big fan of the Cell line from back in the day with the Cell Pearl being my favorite.  So I was pretty pumped to see a Pearl coverstock with the very popular Nucleus Core.
I drilled mine 5 x 5 x 2 a standard pin up above fingers and MB about an inch from thumb.
My initial thoughts was this ball is special.  I think the Nuclear is going to be just as good as the Phaze 3 is on the Storm side.  It's that good of a ball. What I like is that when the Nuclear gets a little too deep in the pocket it still kicks the ten pin out, where other balls would not.  The motion is just very predictable and this ball carries and goes through the pins really well.  Its cleaner that the UFO but with more pop downlane, not flippy just hard arcing.  Just put your favorite layout in the Nuclear and you won't be disappointed.

So far, I’ve been a big fan of most every Cell ball released, especially the Hyper Cell Fused.   #RotoSchlem does it again, this one is a home run!   Super clean through the front, stands up in the mid lane with that big Nucleus core, and won’t quit down the lane and through the pins.  To me it’s a bit longer than a fused overall but mostly back-end.  I've drilled about 30 of these so far and every single person has loved the ball!  This might be one of the best balls I've ever drilled!  This one is so good its like CHEATING!!!!!!  Pins dont stand a chance!
