Even though it is asymmetrical, it has the continuous roll of a symmetrical ball no matter how it is drilled. Cover The all new Radioactive Solid Urethane cover will produce the truest read we have ever seen at Roto Grip. Because it is urethane, it will blend out those over reacting conditions like a boss! Condition This ball was created with one goal in mind, design a urethane ball that provides more punch than all the other urethane balls on the market today. Safe to say we exceeded even our own expectations. No matter how you throw it, this ball rolls true every time and is a must for every tournament arsenal.

    Here To do a ball review and talk about the new Roto grip hot cell.The New hot cell has to be probably one of the best urethane balls put out on the market today,the new hot cell has brand new radioactive solid urethane shell with the original nucleus core from the origional cell.This ball hits like a truck and thats from the core being used in this ball its amazing.And thats been a problem with urethane balls back in the day,did awsome job being used on short patterns and even those tighter patterns where you have to keep the pocket.but had no hitting power at all.but with the hot cell the carry is amazing.Being a Storm Staffer for a long time and when storm produced the pitch black ive been a huge fan of that ball something i will always have in my bag.Now with the hot cell it will give me a little more hook then the pitch black.best 2 urethane balls on the market.I will have this 2 balls in my bag all the time everywhere i go.

    The Roto Grip Hot Cell has the new Radioactive Solid Urethane cover. This cover is pure urethane wrapped around the Nucleus asymmetrical core (the original Cell core). When this ball first came out, I did not drill one immediately and then I partially tore my bicep so I watched a lot of people throw it while I was out healing. I couldn't believe the shape I was seeing out of a urethane ball on patterns that were not hooking a great amount anyway. So, I went with one of my favorite layouts which is 50 x 4.5 x 30 and left it at box (1000). I have tried this ball on a modified 49 foot house pattern with defined friction to the right and a couple medium volume 43 foot house patterns. Simply put, the Hot Cell is urethane on steroids. I have a similarly drilled Pitch Black and the Hot Cell is easily 5-6 more and gets caught in the puddle a lot less often for me.

    The Hot Cell is a new release from Roto Grip, that incorporates one of the most popular cores of all time, the Nucleus core, with a urethane cover called Radioactive. This ball is factory finished with a 1000 grit pad, and is bright red, with orange labels. The core numbers on pre-drilled 15lb Hot Cells are 2.52 rg, 0.056 differential, and 0.018 intermediate differential. With the multitude of varying volumes and lengths of oil patterns these days, it was only inevitable that we would see a urethane covered ball, with a strong asymmetrical core. This ball will fill a niche void in bowlers arsenals when seeing high volume, very short oil patterns. The cover isn't jumpy off the friction, and the core strength allows it to create fresher cover by having a lot of flair, to keep the urethane cover rolling strong through the backend of the lane. I really like this ball, and have been asking for something like it for many years now. Comparing the Hot Cell to a Pitch Black ,with same layout of 4 x 3.5 x 3, and surface prep, the Hot Cell starts up earlier, and has more "hook" and continuation through the pins, forcing me about 3 and 2 right to allow for the added hook. I have been able to use the Hot Cell on the above mentioned short patterns, as well as some very long, low volume patterns, that I just wanted to trap the pocket, but putting enough surface on a reactive ball to get it to slow down the right way, created too much overall hook. THe Hot Cell will be a good choice for bowlers that do not have a high rev rate or super high ball speed, and want a ball to just bump the friction with a controlled shape, rather than have a weaker cored, reactive ball "flip" off the dry part of the lane. Using urethane on today's high volume patterns does have it's disadvantages, though. The cover will not soak up the oil like reactive can, and will lane shine quicker, and carry oil down the lane, more than what a reactive ball will do. Thank you for taking the time to read my review of the Roto Grip Hot Cell.

    I drilled my Hot Cell up 50x4x35. I wanted to get the large amount of flare to help me get this thing rolling. I left it box surface which is 1000 grit. This ball is a pretty neat toy for me to use. The Hot Cell had a large amount of flare compared to the Pitch Black. I had trouble with the Pitch Black getting into enough of a roll for my lower rev style to take advantage of. The Hot Cell picked up strong and got thru the pins very hard. Put this one if your bag if your not heavy handed enough to throw a Pitch series ball but want to see what the new urethane revolution is all about.

    The Roto Grip Hot Cell is Roto Grips new Urethane ball. The Hot Cell is in the HP4 line and contains the Nucleus core which was found in the Cell Line. The ball is finished at 1000 with a Urethane Cover. This ball for me is very different from other balls that I've drilled. I drilled mine with pin above the bridge and mass bias to the right of my thumb. This ball for a urethane hooks quite a bit and hits real hard thanks to the very strong core. The urethane still allowed me to stay straighter on broken down and shorter patterns but it still has the hook potential to recover if you miss right or left. Unlike most Urethanes I've thrown, the Hot cell can handle oil patterns ranging from light oil to medium heavy. It all depends on what angle you want to play. The Hot Cell gives you an array of options and is a must have in everyone's ball bag.

    The Hot Cell is the latest in the world of urethane bowling balls. It combines the smooth and controllable urethane shape with the power of one of the most popular Roto Grip cores to date in the Nucleus core from the Cell series. What the Hot cell does more than anything else is FLARE! The problem that some have with most urethane balls is that the lack of flare creates too much carrydown and not enough power through the pins. The Hot Cell changes all of that. You can now better control the flare and shape because of the asymmetric core. Urethane isn't just for super high-rev players anymore! The Hot Cell is noticeably stronger through the pins for me without sacrificing the benefit of using urethane.

    The Hot Cell is the latest addition to the HP4 line and is a fresh and bold take on urethane. The cover is 100% pure urethane, and the core is the same original Nucleus core that was used in the Cell line. The result is a urethane reaction elevated. One feature of older urethane was also cores with a low differential that did not flare, meaning that the ball continued to roll over the same oil track all the way down the lane. The strength of the Nucleus core causes the Hot Cell to roll and rev unlike other urethane balls, and the flare the core causes exposes a fresh surface of ball to the lane on every rotation which increases traction but also delivers the key benefit of reducing backend carrydown, which improves consistency at the breakpoint substantially over other urethane options that do not flare and as a result tend to cause a significant amount of carrydown. When you pair that with the pure urethane cover, you get a ball that is the type of reaction and amount of hook that people look for in a urethane ball while significantly reducing or possibly eliminating the negative aspects. https://www.youtube.com/watch?v=ro1qTa1LP7U&t=35s

    Speed: 18mph Rev Rate: 450rpm Pattern: Typical House Shot The Hot Cell is a urethane ball I've been waiting for and its finally here. The Hot Cell is the strongest urethane ball Storm or Roto Grip have ever made. It has a strong solid urethane cover with a strong asymmetrical core that was used in the old Cell series bowling balls. At times, my Pitch Black would sometimes have a hard time getting corners out, but the Hot Cell is a great fix for that. It is much stronger than the Pitch Black with that smooth urethane roll still. This ball is a game changer in the urethane world!

    Roto Grip Hot Cell Ball Review by PJ Haggerty After drilling two Pitch Black's and using them on several different patterns, I was excited to see an asymmetrical core in a Urethane ball to create more flare and more motion down lane. The Roto Grip Hot Cell gives us the famous Nucleus core found in the Cell line with a solid Urethane Cover that flares a ton! I've drilled one so far and have been able to use it on multiple patterns. I drilled it with the pin above my bridge and CG just to the right of my thumb. This maps out as 5 x 4.5 x 70. I didn't change the surface at all but as any urethane, you have to continue to put surface on the cover as the oil soaks it up quickly. This gives me a Pitch Black type motion, but certainly gives me more motion down lane. I've mainly used it on flatter and shorter patterns. If you need a new Urethane ball that continues down line, similar to reactive, a Hot Cell is a perfect match! #SquadRG

    The new ball in the RG in HP4 line is the Hot Cell. It uses new Radioactive solid urethane coverstock, with the popular Nucleus core that was in the Cell series. I drilled mine 4 x 5 x 3 or 60 x4 x 55. I have drilled the Storm Pitch Blue and Pitch Black, the Hot Cell is at least 5-6 boards stronger. As with the Asymmetrical core it produces a large amount of flare. I like to say that the Hot Cell is a great choice for bowlers that have less than 500 RPM rev rates. As the Hot Cell can handle the puddle in the middle better and give you strong midlane hook. I am actually able to get left of the dry a little where the pitch series I had to stay on top of the dry. The Hot Cell is a game changer in urethane market today. Brian Watson PAP - 3 5/8 up 1 1/4 Speed - 16-17 Rev Rate - 400 Tilt - 17 Storm/RG pro shop staff

    The Hot Cell was a great ball for a Shorter Pattern on the PBA. I threw the Hot Cell on the Cheetah Pattern and got great results. The ball rolled smoothly down lane with a nice smooth arcing break and great pin reaction. I would definitely recommend this ball for drier lane conditions or shorter lane patterns.

    RotoGrip's answer to the rebirth in urethane is the Hot Cell. The Hot Cell is in the HP4 series of bowling balls. The Hot Cell has a strong urethane shell called Radioactive that surrounds one of the strongest cores... The Nucleus Core! This combination generates huge flare potential and heavy backend roll thru the pins. The layout that I used on the Hot Cell is pin below the ring finger with the cg kick out and down with a hole at 6 inches. My coordinates are 5 5/8 over and ¾ up for my axis point, my rev rate is around 300, ball speed medium (approx. 15mph) and I am right handed. I was lucky enough to throw the Hot Cell and the Pitch Black on several different short patterns and house conditions. The first pattern was the first cheetah where the outside was wide open. The Pitch Black allowed me to play straighter thru the heads and keep the ball in front of me. The Hot Cell was about an arrow stronger and actually generated some recovery for me if I missed right. When carry down happened the Hot Cell was still going through the pins with authority. However, the Pitch Black was just not stronger enough and I had to be perfect to strike. I also threw both on a 34ft Kegel pattern and a typical house condition. The characteristics were the same and I am not going to be redundant. The Hot Cell is a monster compared to any other urethane bowling ball. Urethane is never my first choice but the Hot Cell is not your typical urethane bowling ball. The Hot Cell is an asymmetrical bowling ball that will turn heads because of the color and how hard it goes through the pins!

    Roto Grip Hot Cell 45 x 4 x 45 44ft THS on Kegel Ice oil on older HPL surface – fresh and burned THS Ball at BOX surface – 1000 grit sanded What I like: Did not read early like any other all urethane balls made from Roto Grip or Storm before. It took on the fresh lane conditions quite well and hits super, super hard. Flare is HUGH on it, and really rolls like a weak reactive, but has the hitting power of a mile long freight train. Handle the breakdown even better, never relented throughout practice, recording, or league. At one point several league bowlers gathered behind my pair because they thought I was using some new "test" ball, and then stayed to watch the striking show. On shorter and grittier surfaces or 2nd shift league, this ball will be your main piece for years to come. High Performance, High Striking Power, and Super Durable... @Roto_Schlem #OwnIt #SquadRG #RotoGrip

    HOT CELL Let me start off by saying WOW, WOW and WOW. That maybe enough for this ball review. The first time I got to throw this ball, I took it and my Pitch Black. The center that I practiced on is a 39' medium volume house shot. I got lined up with the Pitch Black and then went to the Hot Cell. I had it in my mind that it would be stronger but wasn't sure how much. So the first shot I moved three boards left with my feet and used the same target. Well three was not enough. So I then moved three more left with my feet and moved my eyes in as well, and this shot went four pin high. So moved two more left and that when the WOW came back into play. I am not a high rev player, but this ball really turns up. As much motion and flare the Hot Cell is really continuous through the pins. It's really surprising to me that it is a urethane cover. As the lanes dried out I could keep moving left and the Hot Cell kept recovering. I have seen other staffers that are straighter players, that can make a home playing up the boards. I believe this ball would benefit any league bowler and every tournament bowler. Great job Roto Grip.

    This was an interesting ball to say the least; a strong asymmetrical urethane bowling ball. The ball features the famous nucleus core from the cell lines and is finished at a strong 1000 grit finish. Normally, I do not throw urethane although I do believe this ball fills a gap for me in certain situations and will provide other bowlers options, as well, in given situations. I tested this ball on a THS (Typical House Shot) and played a few different angles. For me as a tweener and not a high rev guy I did not have much success trying to open my angles up. I did, however, as one would expect, able to play pretty straighter and tighter lines successfully with this ball. The best look I received was standing around board 12 and going up 7 at the arrows. When I constantly hit this line I had that nice smooth ball motion one would expect from urethane. Also, the ball hit well for urethane. I kicked out a few pesky corner pins and was able to shoot messengers across the lane with this ball. This should mitigate some of the concerns bowlers have with urethane in that they note the urethane covers do not hit as hard as reactive bowling balls. What I am looking forward to is trying this ball out on the shorter sport oil conditions and seeing my success on it. I just recently had a tournament where I was bowling on 34' Stockholm and this would have been the ball I would have gone to when I needed to play tighter up the lane lines that require predictability. This is where this ball will fit for me. Check out the video!: https://youtu.be/WA2JhDzRHn0

    Orientation: Right Handed Rev Rate: 375 RPM Speed: 16-17 MPH PAP: 4 5/8 straight across Location: Enterprise Park Lanes, Springfield MO Pattern: High Volume THS Layout: 42.5, 4 ¾, 70 The Hot Cell is the strongest urethane ball Storm or Roto Grip have ever made. It features a strong solid urethane cover and a strong asym core that was used in the Cell series. This thing picks up very early and continues through the pins very well. My Pitch Black would sometimes have a hard time getting corners out, but the Hot Cell is a great fix for that. I would say the Hot Cell is 4-5 boards stronger than the Pitch Black. I get a urethane reaction to the pocket, but asymmetrical ball pin action! For me the Hot Cell is the perfect upgrade from the Pitch Black!
