Length: Short to Medium

Volume: Light to Medium

Type (THS, Sport Pattern etc):THS and Viper

The RotoGrip UpRoar is the pearlized version of the Rumble.  The 51ML Pearl cover stock provides decent length with an aggressive break point. The UpRoar also uses the Late Roll 51 core same as the Rumble. I hand scuffed the cover stock slightly with a 2000 pad just to knock some of the polish off. The layout that I used was 45 X 5 ½ X 75 or Pin above the fingers with a slight cg kick to the right with an X-Hole on my Axis. My PAP is 5 5/8 over and ¾ up, rev rate around 300 and I am Right Handed. 

I threw the UpRoar on a regular house pattern and also on the Viper pattern. What I noticed on both patterns is how easily the UpRoar glides through the front part of the lane. The other noticeable thing that stood out was how readable but aggressive the break point motion was. The UpRoar did not go sideways at the break point unless I just yanked on it at my release. Compared to the Shatter, the UpRoar has the same length but the backend motion was different. The Shatter wanted to jump or flip when it hits the dry boards whereas the UpRoar is a lot smoother. In order to get the Shatter to work on the House pattern my angle was extreme for my liking, feet were at 25 and my eyes were at 11 at the arrows. The UpRoar being more aggressive but smoother my angles were a lot better and more comfortable. I was 5 right with feet and looking at the area with my eyes. I decided to compare the UpRoar to the Rumble. Now with the Rumble out of the box with a 2000 grit finish…. The Rumble rolled earlier and smoother compared to the UpRoar. To try and make it fair I polished the Rumble. The polished Rumble did get more length than the OOB Rumble it did not compare to the overall performance of the UpRoar. The UpRoar gave me the world on the viper pattern with some room left and some room right. The Polished Rumble was either too much or not enough!

The UpRoar will be in my bag when bowling on the shorter patterns!

Likes: The length and readability

UpRoar #1: Layout: 55x4x70
Tested on: 41ft THS and Don Carter pattern
Surface and oil/cleaner: Older HPL and Ice oil with Defense C cleaner
Results: Found this ball worked really well on the THS and playing the track area, did also have good success playing straight up the lane on the Don Carter pattern, even though this has pearl additive, it did not react like a pearl additive ball, the diff on this ball make it a great benchmark ball for any skill level of bowler. When I ran into carry down, it seemed very receptive to the carry down and it kept up the overall shape down lanes where a typical pearl ball would tend to start to slide a little more or hook early. When the Carter pattern starts to give up the front part of the lane, the ball motion did not really changed that much and seemed to be very stable on fresh and used patterns. Great overall performing ball.

For you Pro Shop owners Roto Grip continues to provide a great entry point for new bowlers.  Cheap price and great performance.  The Uproar gives you great length with plenty of backend.  I used it recently on the WTBA Los Angeles pattern and really matched up well.  I could get right on top of the dry but was still able to get it down the lane with a great reaction on the backend. 

Great ball for the shorter oil patterns and a great solution for the new bowlers.

Orientation:  Right Handed
Rev Rate:  400 RPM
Speed:  16-17 MPH
PAP:  5 across ¾ up

Location:  Enterprise Park Lanes, Springfield MO
Pattern:  High Volume THS
Layout:  40, 6, 60 w/p1 hole

Wow!   The high RG/low Diff combo had me worried.  I hadn’t really seen anything like it in a pearl coverstock.  And what I found when I drilled the ball was definitely unique.  The UpRoar is super clean through the heads, but on the back it just rolls.  If I have friction, that ball strikes all day.  And it doesn’t jerk off the dry like some of the other mid performance balls that are designed to go long and sideways. 

The UpRoar was designed to blend over under especially when the heads blow up.  It definitely succeeds.  It feels like I’m throwing a big core high performance ball with the way the UpRoar rolls but somehow it still gets through the heads really well.   

If you’re looking for a heavy rolling ball that gets down the lane every time the UpRoar is your ball.

Roto Grip UpRoar
Right Handed
Experience   Advanced (I have bowled in a league and hold a PBA Card)
League Average   220
Ball Speed   Medium 15-16mph
Style          Cranker
PAP          5 over 1/4" up

PSA Layout - 4" x 4" x 2"
Balance Hole - yes

Surface Preparation - Out of Box (1500 grit polish)

What I Was Looking For from this ball:     A compliment in a pearlized version of the Rumble.  I wanted the same aggressive backend reaction but more length.

What I Ended Up With in the Ball and Layout:     A very strong pearlized ball that hooked hard on the backends.  The ball would hold the line awesome even if I tugged a few or got it a board wide.

I tested this ball on a fresh pattern at my local center. The centers lanes are wood and the house shot isnt easy.  The shot tends to hook early in the middle of the lanes and hang right if you get the ball too far out.  Over the course of 5 games, I played around 15 and sent the ball out to 8 and sometimes went out to 5 to see the recovery.  The Up Roar held my line very well and would even recover when I went a bit wide.  Over the course of the next 10-15 games, the shot got much dryer in the middle and I migrated left with both my mark and my feet.  What I found out is that this ball is very snappy for me when it hits the dry.  With our house shot being tough and tending to be dryer off the breakpoint in the middles, I ended up moving back right and having to change hand positions to stay around the track area.  I did however notice that since this ball is pearlized that it didnt recover much when I got too wide but that is to be expected on the shot we have.  As long as I stayed around the 8 board no matter where I moved my stance, The Up Roar killed the pins.  I have thrown this ball on a long patter as well and found that it works extremely well as long as I have a good backend.   

Overall:    I am very satisfied with this ball and think its an absolute fantastic compliment to the Rumble and one of the best pearlized balls out there.  No over under or unpredictable reactions out of this ball like many other pearlized balls give at all.  A definate must have for Roto Grip fans as well as any bowler wanting a great pearlized ball.

Lay Out: 4.5" from PAP at 60* PAP angle and 30* VAL angle. Dual angle measurement would be 60/4.5/30. The pin ended up about 1/2 above my ring finger with the CG very swung out from the ring finger. I put a weight hole in the P2 area to maintain reaction.

Surface: I hit the box finish with a used 2000 abralon pad.

Purpose: I wanted to drill up this up the same as my Rumble to try to get a nice 1-2 punch to compare to. I had the Riot/Dark Star combo a couple of seasons ago and loved the way they rolled on shorter and lower volume patterns.

Observations: The UpRoar is very much like a sharper version of the Rumble. It is strong but controllable. I put it side by side with a Rumble and it has the same sort of shape, but is sharper off the spot. I hit the surface with a used 2000 pad and that smoothed it out more. This ball could be the Wrecker of 2014 as far as strong top shelf performance at a lower price.

Weight:  14 lbs.
Pin Length:  3”
Drilling:  Pin over ring, CG in palm
Pattern Length:  39 ft.
Pattern Volume:  Light/Medium
Pattern Type:  THS
Right Handed

The UPROAR is a pearl version of the WRECKER.

I used the UPROAR on our 39 ft. THS, at box finish (1500 grit polished).

I found, for me, the UPROAR got through the heads and down lane very smooth, with a nice turn, and heavy roll to the pocket.  The UPROAR is stronger than I originally thought it would be.    I brought the surface up to 2000 grit, polished and found I got the little extra length i was looking for to make this ball a perfect complement to the  WRECKER.   I was able to start the set with my WRECKER. As the lanes transitioned, I was able to pick up the UPROAR, and stay in the same part of the lane.

This is a great piece for Light/Medium oil patterns. It is a great mid priced ball for all levels of bowlers.   If you love the WRECKER, you will definitely be a fan of the UPROAR.

Roto Grip UpRoar Ball Review By Walter McKnight

About the Bowler
Bowling Hand          Right Handed
League Average          230
Sport Shot Average          210
Ball Speed          Fast
Style          Cranker
PAP          5 1/4 1/8

Lane Conditions: Medium-Light Oil
Typical Conditions: Variety of Shots
Type of Lane: Combination
What part of the lane did you play? Second Arrow
Did the ball track out? Normal
Weight of bowling ball: 15
Surface of bowling ball: Factory/Box
What grit was the surface of the ball? 1500
Likes: Smooth transition to the pocket. Very predictable.

The Roto Grip Uproar is the newest edition to the HP2 Line. The Late Roll 51 core combined with the 51ML cover gives this ball ultimate length and recovery. The Uproar has been designed to work best on medium to dry lane conditions. But make no mistake it is very aggressive and a true heavy hitter for its price point. The ball easily reads the mid lane without wasting energy and enters the pocket with a very sharp angle. If you're looking for a ball that can cut through dry lanes without losing energy, this is the ball for you.

My Axis is 4 7/8 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.

Drilled this ball 50 x 5’ x 30 (5 ½” x 4 ½” x 2 ½”)

I’ve had success with this ball after the lanes get broken down because it goes long before it makes a sharp turn on the back end.  I’ve also been able to move right and play straight thru the heads and get incredible carry due to the very angular back ends it creates.  This ball will work well for people with a lot of hand, a dryer condition, or one who likes to play straight up the boards and still get that sharp back end reaction.

Ball specs – 15 lbs 2 oz, 2.48 top weight, 2.75 inch pin.

The Uproar, a pearl in the HP2 line, was drilled using the dual angle method.  The layout is a 60 X 4.5 X 55.  An x-hole was not needed. Using Storm’s layout terminology the layout would be 4.5 by 4.75 with a 3 7/8 inch pin buffer.  The cover was left OOB which is 1500 polished. 

The Uproar, a weaker pearl with a 51 grit rating, was thrown on a fresh 41 foot, 24 micro liter house shot.  The Uproar was super clean through the fronts, did not read the mids consistently and did not go through the pins very well.  I added a flare increasing X-hole at the intersection of the VAL and a line drawn from the grip center through the CG to the VAL. This did improve the overall motion of the Uproar but there are better ball choices in the Roto Grip lineup for this lane condition.  The Uproar will excel on conditions that provide some friction as demonstrated by Belmonte’s and Malott’s recent success using it.

I tested my UpRoar on my 39-foot house shot.  The 1500 polished pearl finish worked well for this condition. I pushed the ball to the dry area to gain some friction.

My UpRoar is drilled with the pin up above the fingers and a dual thumb hole layout..  I wanted to have a ball that would compliment my Deranged and have a nice skid flip reaction. This ball produced about 3-5 inches of flare.  The ball skidded nicely through the heads as I played just inside the oil line skidding out to the dryer boards.  Once the ball encountered some friction, it revved up nicely and made a pronounced move to the pocket. 
As with all Roto Grip balls, it drove through the pin deck.

The UpRoar has a very predictable reaction, and with the 2.55 RG and .042 differential makes it a great addition for the lower rev medium speed league player who needs the extra length from the polished cover when the lanes begin to breakdown.

What I enjoyed the most about this ball is the late breaking skid flip reaction. It produced a nice dramatic hook to the pocket and devastated the pins. What a fun ball to throw.

The UpRoar is a nice go to ball for the league bowler and is good compliment to the Deranged and Asylum.  This ball will make a nice addition to anyone’s arsenal.

I originally tested the Uproar on a house pattern and was definitely impressed.  Typically on house patterns, I like to use stronger, slower responsive balls to prevent a ‘cliffed’ reaction.   We bowl on a very high friction surface and this ball comes into play as the lanes transition and I have to move left and open up my angles.  With any new balls I drill that come out very shiny, I usually take the surface down by hand to smooth out the shape.  After about ten shots, I knocked the surface down with a used 2000 pad and the Uproar still cleared the front of the lane with ease and slowed down the response time down lane.

 8)The one I drilled has the pin above my bridge with a large shift and a hole on my axis.  This measures out to 5 1/8 x 3 with a 31/32 hole on my axis.  I’ve had more success with putting larger weight holes in balls with lower differentials.  I feel this helps the ball read the body of the lane and create a smoother motion.  It also helps the ball flare and create a predictable motion.  I can see the Uproar being used on all types of conditions on all types of surfaces.  There will definitely be a need for friction, as the cover and core are on the mid to lower end.  But, it’s a great shape that the straighter players will be able to play farther to the right with when the lanes start to burn up.   The high rev guys (watch Belmo at the TOC & Masters) can move left, open up their angles, and create more of an arc shape down lane.

Go drill one!!!

Roto Grip Uproar
Right handed
Rev Rate - 400
Speed - Medium
PAP 4 up 1 1/4

The RotoGrip UpRoar is the pearlized version of the Rumble.  With a low diff. of 0.030 and high RG 2.55.  There was some reviews about this ball being flippy on the backend. Even with a pearl cover I personally get an earlier roll with nice continuous smooth arcing motion.  With the Late Roll 51 core, the Uproar is very predictable.  As you have seen Belmo use the Uproar a lot on TV this year.  Very good ball for sport and PBA.  But also very good option for those house shots that are a little on the light side with the oil.  I drilled mine with a 5 1/2 inch pin above my middle finger.  With this drilling the Uproar also allows me play on the fresh better as I don't see a big change in direction off of the spot.  High rev guys will really like this ball as it is so controllable down lane when they have to get deep and open up the lane.  If you liked the Rumble you will definitely like the pear version Uproar.

The Roto Grip Up Roar is the latest release in the HP-2 line of balls. It is the follow up to the Rumble. The Up Roar has a 1500 grit polished pearl 51ML cover stock. This is the same cover that was used on the Shatter. The core is the Late Roll 51 that debuted in the Rumble. The numbers come in at 2.55 RG with a differential of 0.030 in 15lbs. The Up Roar has bright shelf appeal with its orange and ruby pearl color combination.
I drilled my Up Roar with pin over ring, CG on my grip line, with the 6 ¾” virtual MB in my initial ball track. This comes out to 5 ¼ x6 ½ x2 ½ using the Storm system of laying out a ball. I left the ball at the box finish. The comp balls will be my current Rumble with a 4x6½ x2½ layout and a Shatter, with the same layout as the Up Roar.
The Up Roar is very clean to the break point for me. It doesn’t jump off the dry as hard as some of my Storm balls, but is a very strong move compared to my other Roto Grip pieces. This ball needs DRY backends to slow it down. It is an excellent complement to the Rumble in that it affords me about 3 to 4 more feet of length compared to the Rumble with box finish, and a more pronounced move to the pocket. The Up Roar is about 2-3 boards less overall than the Shatter. The decrease in the differential really changes the shape of this ball as it rolls through the backend of the lane. Since the core doesn’t allow the ball to rev up as fast, the move is much more sudden than that of the Shatter, once encountering friction. I really like the Shatter a lot, but sometimes find it to be too much overall hook when the lane starts to dry up based on the cover and core relationship. The Up Roar seems to be the solution, for my style of bowling.
I like the Up Roar for broken down conditions. I also liked how this ball worked for me at Doug Kent’s bowling center, during his Brockmeyer Open event. Doug has wood lanes, and uses a very difficult pattern. The up Roar allowed me to trap the middle of the lane, and grind out, making the first cut.
I probably wouldn’t reach for the Up Roar as the first ball out of the bag on freshly oiled synthetic lanes(unless it is a very low volume), as it will be too skid flippy for my ball speed. I could see where someone who is speed dominate and wants to play the dry, would be able to use it on fresh oiled synthetics though. I can also see bowlers with slower ball speed and higher rev rates will see use of this ball on medium conditions. For me, as my ball speed and rev rate are fairly well matched, I will use it more on the broken down conditions and wood lanes where I need a clean move to the breakpoint.
Thank you for taking the time to read my review of the Roto Grip Up Roar.
