Ball: Devour
Layout: 50 x 3 ½ x 50
Surface: box condition
Test patterns: 41ft THS and 37ft sport pattern
Outcome: I tested this ball along with iQ Tour solid and the balls were identical in reaction. Ultra smooth and predictable, and great pin carry. Just like my Tour, once it shined up a little, I was able to keep playing the same part of the lane, shot after shot, a lot of other balls you need to start moving or adjusting after a game or so, I found this ball to almost adapt itself to the changes in the breakdown of the pattern. I was able to move left and go up the gutter and also move deep inside and play 4th arrow and have the confidence I was going to have the same reaction shot after shot. If you are lacking ball speed, this will be a great ball for you, amazing pin carry when I slowed down to about 14 to 15 mph… Amazing ball for both sport and house patterns. A ball you can use across a range of short to long patterns which is hard to find in this day of age of “specialized” ball making. If you liked the iQ Tour solid, then you would LOVE this ball.

Roto Grip Devour Review by Casey Murphy

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:  45, 6, 40

The Devour could be called the Wrecker “Tour Edition”. Roto Grip took the Wrecker Core and raised the RG and lowered the Diff.  This makes for a solid that is very clean in the front and recovers plenty down lane, especially for a solid.  This is not a new Rumble, which for me was a little too early and didn’t nearly do enough on the back part of the lane.  The Devour is hopefully the first in a new line of Mid RG/Lower Diff balls in the HP2 line (UpRoar, Outcry) that will be making permanent homes in the back of tournament bowlers.  The Devour is smooth enough to use on the fresh but can also be a go to ball late when you need to get a corner out from in deep.

  The Devour is the new ball in the RG HP2 line.   I really liked the Outcry, so I was glad to see RG come out with a solid in that line.  I drilled mine 5 1/4 x 4 x 4  1/2 pin down.
I first tried the Devour on a couple Kegel patterns, with the weaker pin the ball just wasn't enough with original surface.  I hit it with a 1000 pad and it gave me the extra help that I was looking for.  Very smooth and predictable roll.  Then I sanded it to 3000 and then applied Storm Polish to use in league.  Our league shot is a little on the dry side, especially with a very defined track area. I shoot 279-289-212 first night in league.  The ball gave good midlane roll and very good continuation downlane.  The Devour had great carry.  I would compared it to Storm IQ Tour, with a little less overall hook potential.  I was able to go up the lane and also move in and go around it when they dried out.  Great addition to the RG HP2 line!

Roto Grip Devour Review by Storm Staffer Matthew Kemper

Type (THS, Sport Pattern etc):Wood


Likes:Very smooth reaction and very predictable.  Hitting power is strong for a weaker ball, ball is a little stronger overall for that line of balls

Dislikes: None

The Roto Grip Devour is Roto Grips newest HP2 release.  The ball is a solid reactive ball.  Overall the ball is much stronger than one would think coming from the HP2 line.  The ball is very smooth.  I drilled mine with a 60x5x25 layout.  For me it’s a stacked layout which gives the ball a lot of length and a smoother backend reaction.  This is one of my favorite layouts and it matched the ball real well.  The ball is smooth through the fronts which is nice for a solid.  The ball also has a nice readable reaction down lane.  The Devour also recovers well when missing my target to the right.  It’s a very versatile ball overall.

I recommend this ball to any league bowler because of its versatility on house shots. It is considered a weaker ball compared to the HP3 and HP4 lines so it allows a bowler to start further right on fresh and gradually move left when the lanes break down.  It has a smooth reaction and it doesn’t lose its hitting power when you have to move further inside on the broken down lanes.

Devour review by staffer Tony Marino

The Roto Grip Devour is the combination of the all-new Late Roll 56 (LR56) core, and combines it with the 54MH solid coverstock. 

I have average to above average ball speed (~17MPH) which tends to balance out my rev rate. I drilled my Devour with my favorite tame and predictable layout of 2” x 5” with a 2” pin buffer and a neutral weight hole.

I have thrown the Devour on house patterns, as well as a few flatter Kegel oil pattern.  The first thing I noticed about this ball was how smooth and predictable it rolled. Even though the new LR56 core has a 2.56 radius of gyration (RG), the addition of the 54MH solid cover gives it a very smooth motion that is not overly aggressive downlane. The Devour is the definition of a benchmark ball. The 54MH coverstock is a middle of the road cover that is meant for medium to heavy oil, and it fits that bill. It is one of the most versatile covers in my bag. I have used it with success with anywhere from 800 grit sanded, to 2,000 grit polished. This ball will roll great for a wide variety of styles. I see a lot of the same qualities in the Devour that I see in the Storm IQ Tour. Because of my speed and roll, I tend to use a lot of solid covers, and the Devour gives me very smooth motion still drive very strong through the pins.

I am very impressed with the new Roto Grip Devour. I am a big fan of all the balls in the HP2 line and the Devour fits right in with them. The Devour has such a controlled roll which everyone loves to see out of a ball. Compared to the Roto Grip Outcry, the Devour gets down lane cleaner with the similar smooth heavy roll down lane. This ball is great for all conditions, but is really effective late in the day on a more burnt up condition. When there is a bunch of friction this ball just blends it all out. A recommend the Roto Grip Devour to everyone who wants a smooth, clean, and predictable rolling ball.

Length: Various Lengths

Volume: Various Volumes

Type (THS, Sport Pattern etc): Various Patterns

The newest addition to HP2 line from RotoGrip is the Devour.  The Devour uses the new Late Roll 55 Core and the 54MH Solid Reactive Coverstock.  This combination allows the Devour to navigate down the lane with a strong motion on the backend.  The Devour is the only ball in the HP2 line that is a Solid Reactive Coverstock giving the HP2 line added versatility!

I drilled my Devour pin over the bridge with the CG slightly kicked out with no extra hole.  The coordinates for the Dual angle people are 75 X 5 ½ by 45.  The Devour comes with a 3000 grit finish from the factory and I did not touch it. My coordinates are PAP 5 5/8 by ¾, Rev Rate around 300, more up the back release and my balls speed is around 15mph.  I like to go straighter if possible.

I was able to throw the Devour on several different conditions and against most of the bowling balls in the HP2 line.  The first thing that I noticed right away was how smooth and readable the Devour was compared to the other bowling balls in the HP2 line.  The Devour on a regular house pattern is stronger throughout the lane than the OutCry.  The OutCry is easily 5 boards weaker than the Devour.  The Devour is smoother than the UpRoar and the over under is almost eliminated.  However, the UpRoar will be in play as soon as the heads get dryer and condition starts to really carry down.  The Devour because the coverstock is solid it just does not have enough energy retention to get around the corner like an UpRoar but has more backend than an OutCry.  On the shorter patterns (Cheetah and anything shorter than 39 feet), the Devour eliminates the over under especially down the lane with a readable but strong backend motion.  The UpRoar and OutCry allow you to either play more area (UpRoar because of the strength of the backend) or play straighter (OutCry because of its longer length).  The Devour sits between them quite nicely.  On the medium patterns, the comparison stays the same but the Devour is more versatile than the other two bowling balls.  The conditions were longer and had a touch more volume and OutCry was not strong enough and the UpRoar was too drastic on the backend.  The Devour was strong enough in the front and had enough backend motion to provide a devastating ball motion.  The Devour is a good fit in the HP2 line.

Roto Grip Devour

Layout: 70 X 5" X 40

Box Finish

Bowler Info:
325 Rev Rate
Speed: 16 - 17 MPH
Pap - 4 7/16 over, 3/8 up

The Devour is easily one of the strongest overall bowling balls in it's lower/mid range price point, and is strong enough to use on medium to medium heavy lane conditions.  It has quite a bit of midlane traction and downlane continuation.  It is also a good ball to use on sport conditions because of the amount of control and smoothness that it possesses.  While the Devour is not a weak ball, it is still 4-5 boards weaker than the Menace; the Menace being one of the stronger balls on the market.

Layout: 65 x 5 x 35 - box finish.

I drilled up the Devour to give me something closer to a benchmark reaction like the Storm IQ Tour. The IQ Tour is a great read ball and the Devour is very close to this reaction. My Devour is best for me when there is some friction to the right of target. The Devour didn't back off at all. If you are thinking of some older Roto releases and where this might fit, think the RG Riot. Very similar type reaction. If you are getting too early of burn due to the 3000 finish, slap a coat of polish on it and watch it push with good energy in the back.

I originally held off drilling this ball while dabbling between various layouts and concepts. What I was looking for was a smooth solid that gave me more length than my Haywire and retained more energy than most solids without having to shine the cover. I've had great success over the years with symmetric solids and lower flaring layouts due to the wet/dry that is created with our house shot here in Central Texas. What I ended up with was EXACTLY what I wanted. I used a strong pin/tame PSA placement with a fairly neutral buffer and it gave me excellent midlane read without using up too much energy, saving plenty of angle downlane. The new and improved Late Roll 56 core is sneakily angular. It's provides a very controlled motion but does not lack "flip". It is an excellent step down from the Menace and Haywire but, as proven with the HP2 line, can absolutely stand it's ground on it's own. This ball is plenty strong for the price tag and will find its way into a variety of players' bags. #OwnIt

Roto Grip Devour Ball Review by PJ Haggerty

The new Devour by Roto Grip is the latest addition to the HP2 line.  A ball that gets down the lane very easily, but with a solid cover, provides a smoother motion off the spot.  With the Late Roll core, this creates more length that can benefit players when there’s more friction or can help the lower rev players stay farther right longer on top of the friction. 

Whenever I drill balls with smaller cores, I try to drill them stronger to make sure they flare enough.  If you drill a weaker ball too weak, they won’t flare enough.  I drilled my Devour as follows: 4x 3 ½ with a hole two inches below my axis.  This ball has seen the most action during the first couple games of flatter patterns to provide a smoother motion, late in blocks when I need a clean and smooth reaction, and on shorter patterns when I need a slower response time and want to stay farther right.

I think the Devour is a nice compliment to the Menace, Haywire, Lock, and IQ series.  A smaller core with a solid, smooth cover can be useful in many ways as discussed above.  I’m excited about this addition.  It fills a gap in my bag and in a very nice way.

Devour review by Mark Tarkington

Right Handed
Ball weight:  15
Rev Rate:  378
Ball Speed:  18.2
Axis Tilt:  7
Axis Rotation:  45*
PAP:  3 3/4 horizontal, 7/8 up
Layout:  70 x 3 1/2 x 75 P3 Hole

As the Menace is a ball up for my Crux Pearl, the Devour is to be a ball down.

I’m not sure it really fits that description.

I’ve only got a few games on the Devour and it’s quite a bit stronger than I had anticipated.  I’ve used it on our house pattern with some success, but I was standing 35, and sending it to the gutter, just to stay right of the head pin.  I did some moving around trying to find the best look for the pocket, but it was just so strong.  At the box finish, it would glide through the fronts and make a nasty move as soon as it encounters friction.  I was able to get through the game before I had to put it away.

Before its next outing, I applied Storm Step 1 compound, hoping to weaken it just a bit.  Oh, but no, the step 2 just did exactly what shine is supposed to, it made the ball even sharper than before.  I was trying this on Kegel Turnpike pattern and it was just too much.  Unless it was on target at 40 foot, it was no good.  If I missed right at all, it was a 0 for the first ball (that happened twice in 4 baker games…), if I missed left, it was just dead left.  Now, this isn’t a problem with the ball, this is a problem with the idiot trying to use the wrong ball on a difficult pattern.

I really need to get more games on the Devour and will be knocking that shine off before the next time it travels down the lane.  I will probably hit it with a white or gray pad, just to get it to read a bit earlier and smoothen it out.

The Devour is a good ball and it will be a great addition to my bags, but I will need to work with it to determine exactly where it fits.

My first thought of the Devour was that it reminded me of an IQ Tour! It is the newest ball in Roto Grip's HP2 line, and with the Wrecker core (which personally I was a big fan of) and adding a solid cover, it gives you a different reaction that most bowling balls.  My laid the ball out 50x5x70 which allows it to get through the front part of the lane and allows it to roll continuously off the spot. Personally, I think it will be great for me on high friction surfaces or when the back ends are strong.  In my opinion, this ball complements the Haywire, IQ Tour and Lock very well and is a nice addition to the Roto Grip series.  This ball certainly packs a punch!!

The Devour is in the HP2 line of balls from Roto Grip. This solid, 3000 grit pad finished ball has an Rg of 2.56, and a differential of 0.034, in 15lbs. The Devour has a core called Late Roll 56, which is a slightly modified version of the core that is in the ever popular Wrecker. The black and yellow color combination also creates the illusion of some green in the ball. I drilled the Devour with the pin just to the left of my ring finger, and cg in the grip, no extra hole. This is the same layout as I used on my Rumble, 4¼ x 5 x 3.

Comparing the Devour to my Rumble, the Devour reads the midlane harder, with more of a hook set motion than the Rumble. The Rumble archs through the backend more than the Devour. The Devour reads oil well, and can give the bowler a cheaper ball that has some read of oil, at a lower price point. The Devour can also be polished. I used Storm step #1, and smoothed out the cover to get more length out of the ball. Polishing the cover also gave me a little more backend motion.

I feel the Devour is a good ball for bowlers who are on a budget, and wants a ball for medium to medium heavy oil, that doesn’t cover a lot of boards. More speed dominant players will like the Devour on medium conditions, and rev dominant players will like this ball on medium to medium heavy oiled conditions.
