Rumble: Layout: 50 x 4 x 45 (my favorite layout) … box condition… 
Tested on: 41 ft THS with HPL with ICE oil and Beaten Path with ICE oil.
The Rumble proved to be a little longer in length and more of a roller in the backend. On the THS I moved into 27 and looked at 15-18 and allowed the ball to break around 7-9 area and the ball did not hook early or roll out like balls I had prior like the Bersek and Riot. I found this ball very forgiving when missing left on both the THS and KEGEL pattern. On the KEGEL pattern, I actually stood at 30 and played 17-20 and used the 12-13 area as a break point… This ball held up even when carry down became a factor with the other bowlers that were practicing with me. This will be a great benchmark ball for lower speed player and for bowlers that like that very predictable roll and hook.

This is my control ball. I drilled it 6 x 5-1/2 and left the factory finish 2000 grit on my Rumble. I go right to this ball when my benchmark balls have trouble staying in the pocket.
The 2000 grit factory finish is clean through the heads without being squirty or grabby and the layout keeps over/under to a minimum. On a 42' THS I slid 24 and got it anywhere from 11-14 at the arrows and hit the pocket strong. I had 2-3 board area at the breakpoint. The ball keeps the pins low on the deck and I recommend it for bowlers that encounter competitive and /or difficult lane conditions.

Weight:  14 lbs.
Pin Length:  3 1/2 “
Drilling:  Pin above ring finger, CG in palm
Pattern Length:  40 ft.
Pattern Volume:  Light/Medium
Pattern Type:  THS

I tested the RUMBLE on 40 ft. THS, at 2000 grit abralon box finish.

I was surprised at how well this ball got through the heads.  It’s  very smooth down lane and makes a nice even, although strong, turn to the pocket.  It has a very strong even motion overall.  Very hard hitting, continuing right through the pin deck.  This ball is a great complement to the WRECKER.  I have been starting with the RUMBLE, and when the heads start to burn and I need more length, I can pull out the WRECKER.  I find the RUMBLE and the WRECKER make a good One Two punch for me on our house pattern. 

A great addition to any arsenal!

Rumble review by staffer Mark Tarkington
« Reply #4 on: August 30, 2013, 10:06:58 AM »
Right Handed
Ball weight:  14
Rev Rate:  378
Ball Speed:  18.2
Axis Tilt:  6.67
Axis Rotation:  45*
PAP:  3 7/8 horizontal, 1 ¼ up
Layout:  2 x 5 pin to pap

After reading up on this one, I decided it would be my new control ball for short patterns and really beaten up shots.

Out of the box, I took it to 4000 Abralon and polished with Storm Xtra Shine.  I really want it to get through the heads…

I took this to a tournament where they were putting out Cheetah and assumed this ball could be an early option.  With the volume they put out, it was not a first-out-of-the-bag option.

During the practice session, using multiple balls, I found that after the shot was getting worn down, the Rumble rolled quite well out where the pattern is supposed to be played.  I was able to set the ball around 6-7 and send it out to anywhere from 1-3 and it was quite controllable and made a nice recovery.  With the polish it made it through the heads and was not too sharp at the end of the pattern.  After the practice session, I assumed that by game 4 or 5, I would be using this ball.

When the actual tournament started the next day, the pattern started off a bit tighter than the day before.  Cycling through my equipment as necessary, I didn’t use the Rumble until game 6 and was only able to use it for about one game.  When I was able to use it, I was quite impressed how well it handled the beat up outsides and carry down from the urethanes we had been following.  The Rumble actually allowed me to open up the lane a bit more that I would have expected.  I really didn’t want to put it down for game 7, but it was covering too many boards and moving left on a beat up Cheetah wasn’t going to help my game.

All in all, with my layout, the ball was quite clean and very smooth.  The Rumble carried very well and I am looking forward to using it on a variety of patterns.

A very nice addition to my tournament arsenal.

Lay Out: 4.5" from PAP at 60* PAP angle and 32* VAL angle. Dual angle measurement would be 60/4.5/32. The pin ended up about 1.5" above my ring finger with the CG slightly swung out from the ring finger. The 60* angle put the RG about an inch right of my thumb. I also have a weight hole 5" straight across the center line.

Surface: I am box finish which is 2000 abralon.

Purpose: I wanted to drill up this up to try to fill a benchmark type reaction my arsenal is badly missing.

Lane Condition Observations: I have thrown this on a couple of different patterns: PBA X Chameleon, modified Chameleon ran to 45', and 2 different volume/length house shots on Pro Anvilane. The Rumble was only out of it's element on the 45' shot; It just didn't have the teeth or motor to make any real kind of move off the spot on this pattern. On the house shots, it was smooth off the friction almost like I could keep it closer or in the friction more than my stronger balls like the Marvel-S, Lucid, and Disturbed.

Response to Friction: The Rumble in box condition is a medium to slower response ball. This one reeks of control and gives the impression even shined up some, it will stay in control.
Other Ball Comparisions: I threw it with my Deranged, Lucid, Shout, and Lights Out. Compared to my Deranged, the Rumble is smoother off the spot and not as jerky. The Deranged makes a good strong move off friction and is a higher response ball. My Lucid is still 4000 box and it gets up in the backend stronger than the Rumble. Again another quicker response ball. The Shout gets thru the fronts better event the new duller Shout 2013 gets a lot further downlane then the Rumble. My Lights Out is close reaction wise, but it has to start in the oil first. If I get the Lights Out in the friction too early it checks faster while the Rumble just slows down.

Final Thoughts: If your looking for something that reminds you of the Riot from a couple of years ago, then get a Rumble or two in your bag. A real nice step up from the HP1 line of balls also as it reads earlier and more predictably than the newer Shout 2013 which has the same 2000 surface on it. To use as a true benchmark though, you might need something with a little stronger core/cover combo like a IQ Tour or a solid-based hybrid like the newer Reign On.

Length: Various conditions

Volume: Various volumes

Type (THS, Sport Pattern etc):Various Patterns

The Roto Grip Rumble is HP-2 line along with the Shatter and the Wrecker. The Rumble is a Solid cover stock that complements the Shatter which is a pearl cover stock and Wrecker which is a Hybrid cover stock. The Rumble does not have the skid flip motion of the Shatter or the Wrecker but it does have decent length and a very continuous backend motion.

The Layout that I used for the Rumble is 45 X 5 ½ X 45 with an X hole 7 inches from the center of my grip or the Pin Above the fingers with a 7 inch hole. My PAP is 5 5/8 over and ¾ up, rev rate around 300, ball speed around 15MPH and I am right handed.

For my review I threw the Rumble and the Shatter and compared the differences. Both balls have similar layouts (Pin over the fingers with an x hole) and I kept them at box finish so with the Rumble being at 2000 and dull and the Shatter at 1500 and Polished there was a noticeable difference in length. The Rumble rolled earlier and more continuous were as the Shatter was a more Skid Flip ball motion. On the Typical House Pattern were I was throwing the two balls, I was farther left with my feet and my target line was also a little farther left with the Rumble compared to the Shatter. The reason is the Rumble at box surface needs some oil in the front part of the lane in order to store energy for the best results. I decided to polish the Rumble and see what would happen. The polished Rumble did skid more through the front part of the lane and more energy for the break point. However, the continuous ball motion was still there compared to the Skid Flipping ball motion of the Shatter.

I also used the Rumble on various tournament conditions and was surprised by the versatility. The Rumble is a solid ball that gives you enough length and backend motion to use when the pattern is “tricky” or transitioning. My best results have been later in the block (games 3 to 4) especially on medium length patterns with medium volume. What I have noticed is that for me it is a good in between ball. When the Disturbed or IQ solid is too much ball but a pearl cover is too jumpy… That is where the Rumble fits for me. The Rumble provides that consistent but strong ball motion. 

The Rumble will always be in my bag when I going to a tournament.

Likes: Strong continuous ball motion

Dislikes: Maybe a little early sometimes

The layout selection used was based on the Storm VLS system and suggestions made by Mr. Steve Kloempken of Storm.  My thanks to Mr. Kloempken for his suggestions, time and knowledge.

Ball specs – 15 lbs 2 oz, 2.75top weight, and 3.5-inch pin.

The Rumble was drilled with a low RG layout as follows; using Dual Angle terminology - 2 inch pin distance, 60 degree drill angle and a 40 degree VAL angle. Using Storm’s drilling methodology the layout is 2  X  5.5  X  .75  pin buffer.  An X-hole was needed and placed in the P2.5 location.  The surface was left OOB which is 2000 dull.

The Rumble is the latest symmetrical, solid in the HP2 line.  I initially threw the Rumble on the USBC White #2 pattern.  What surprised me the most was the length down the lane the Rumble provided.  With the cover at 2000 I was expecting an earlier read.  The chosen layout combined with a .030 differential and mild cover provided a smooth and predictable motion on the back end.  The flare rings were fairly tight.  I would rate hit and carry as above average.  The Rumble is definitely more of control ball when compared to the big backend of the Wrecker (hybrid) and Shatter (pearl) in the HP2 line.

With the selected layout, the Rumble will allow me to play with more closed angles and closer to the friction on fresh medium and perhaps fresh medium-light conditions.  Unless you have a lot hand the Rumble will need to see some friction to get it going.

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.

Drill pin 4” from PAP and CG 4 ½” from PAP.

I was looking for a strong, even, heavy roll with this and with my release that’s what I got.  I’ve used it on heavy oil patterns that I played straight through the fronts and it rolls great.  It starts turning well at mid lane and keeps on going.  The ball has a lot more back end reaction than I expected.  I’ve put it as low as 1000 grit on this ball and love it on oil, even the PBA 50’ pattern.  For oil this is probably my favorite ball.  I’ve even had success on wet house patterns.  For an even, predictable roll this ball is great.

I tested the Rumble both a house shot and on PBA conditions.  This ball proved to be very predictable under both conditions.

My Rumbled is drilled with the pin above the fingers keeping the box finish.  This ball was clean through the front end and produced about 4 inches of flare.  The ball rolled strong off my hand and in the mid-lane the ball began it roll early and made a solid, smooth move to the pocket. 

The Rumble has a very predictable reaction, which is ideal for the league player. As the lanes transition, I could simply move left, play a little deeper and continue to use this ball.

What I enjoyed the most about this ball is the predictability of the cover. It produced a nice steady hook to the pocket.  I was getting 4-5 inches of flair and bouncing the ball off the dry all night.

The Rumble will make a nice addition to anyone’s arsenal.

Rumble review by Staffer Garrett Richardson

Hand: Left
Ball Speed: 16-17mph
Ball Weight: 15lbs
PAP: 5 left 7/16 up
Degrees of Tilt: 17
Layout: 4 ½ x 4 ½ x 3 ½

The Rumble is a great edition to the Roto Grip mid to low performance line up. With the solid cover stock and the new Late Roll 51 weight block it is the smoothest reaction ball in the HP2 line up. The Rumble has the pin drilled into the ring finger with the cg in and no hole. I am able to play straight up the boards which I usually cannot do with a solid but with it being a weaker (but still strong) solid than all the other solid balls I have it is very versatile, predictable and a smooth back end motion. Once the lanes open up and the outside line is starting to dry up and the Rumble starts to jump I am able to move more right to my A game and does not over read but keeps a good line until it gets to the back end and makes a smooth turn with a lot of power for a mid to low end solid. The Rumble is a great ball for someone who wants something smooth but not super strong at a lower price.

Sleeper...WOW, I was extremely surprised, this ball is now the first ball out of my bag on house shots. I use to take the Disturbed out first, but since drilling my Rumbles it's now the first ball out. The Disturbed on some house shots was to strong, but the Rumble is AWESOME.
I used the Rumble (box finish) on a house shot playing up the boards, crossing 10th board out to the 5th board with the ball floating through the fronts with a continuous strong arc on the backend. The Rumble really drives through the pins. I could use the Rumble all day,  the house shot never got to dry for me. As long as I had some oil in the fronts I could keep moving left and the Rumble stayed in play.
I used it on some sport patterns, I struggled with it on the heavier patterns, but the lighter sport patterns it looked like a champ... I really like it on the lighter patterns.
This ball would be a great fit for most every league bowlers on most house shots. On the lighter sport patterns it would be a great addition to most every bowler.

The Roto Grip Rumble is a solid covered ball in the HP2 line and is the follow up to the Shatter and Wrecker bowling balls. The Rumble has a different core shape called Late Roll 51. This produces less flare than the Neutron core, and an overall more controllable reaction. The Rumble has the 55M cover and comes from factory with a 2000 abralon finish and is orange and black. The Rumble has an RG of 2.55 and a differential of .030 in 15lb balls.
The Rumble is much more controllable than the Wrecker. It allows me to play straighter angles through the front of the lane (with some volume up front), and just smoothes out the backend reaction. There are times when you need this kind of reaction, especially when the lane is playing a little tricky, and you just want to control the pocket and leave makeable spares when you miss. The Rumble is a ball that would be good for the “bench mark” tag, as it is predicable and continuous. The Rumble is also a good step down from the Disturbed, when you still need surface on your ball and don’t want a lot of change of direction in the back part of the lane.
There are plenty of bowling balls on the market that cover lots of boards and make for high risk high reward bowling. The Rumble is a ball to throw when you just want to score and keep your angles in front of you. It’s not flashy, and it doesn’t hook the entire lane, and that is a great thing.  It reminds me of what urethane rolls like when used on the proper volume of oil for a urethane ball.
The Rumble will be a great ball for just about every bowler, as long as he or she uses it in the right capacity. The high rev bowlers will get better control of the pocket as well as bowlers that have a lot of axis of rotation. Straighties will like the fact that you can go up the boards with it, and not get it to over react on the drier boards and see some “freeze” at the pocket. I’m considered a tweener, and I like the fact that I can play closer to the straighties line, and take advantage of entry angle with the Rumble. If I need to hook the lane, then I would go to a different ball, as my release strength wouldn’t afford me a very high carry percentage from inside.
The Rumble will find a home on most medium conditions, steering clear of the really dry and really oily lanes. There are lots of other balls on the market that will work for those conditions. The Rumble is just a good solid performer and gets the job done, to be plain and simple. Thank you for reading my review of the Roto Grip Rumble.

  The RG Rumble is the latest symmetrical in the HP2 Line.  I used the Storm VLS system and the drilling came out to be 4 5/8 x 3 1/4 3 1/4.  My pap is 4 up 1  1/4.
The Rumble is a very smooth and controllable ball.  Its a ball reaction that will allow you to play straighter through fronts and predictable move off of the spot.  It has a medium to slower response to the friction.  Similar reaction to the RG Riot, but I think it is a hair stronger than the Riot. The Rumble will be a good fit for medium house shots.  Probably would steer away for the real dry conditions or really tight conditions, but there are other balls for those patterns.  I think the Rumble is good for when the lane conditions can spotty or tricky as it will help smooth out the reaction.

Another great ball from Roto Grip King of Them All.

Rotogrip Rumble
PAP-5 over and ½ up
Ball Speed: 15-17mph
Rev Rate: 300-500
Right Handed
Layout:  Basic pin up with ½ side weight
Surface Preparation: OTB

What I wanted from this ball:  Late roll with a strong continuation to the pocket
Result:  Exactly what I wanted. 

Being a huge fan of the wrecker, I wanted this ball to stronger with a more violent backend reaction.  This is exactly what I got from this ball.  I didn’t alter the surface at all and went with a strong drill pattern for me.  I did not put a weight hole in this ball, but did put about ½ ounce side weight to help it move.

I tested this ball on our home wood lanes with our house pattern.  Our house pattern is a tough shot with dry heads in the middle portion of the lanes from 10-10 and a huge early backend and a hold area from 10-5 with a massive out of bounds 5 and out.

I bowled 3 games keeping this ball around the 10 board and scored great.  I managed to get great length and a hard continuing backend reaction towards the pocket.  The carry was awesome and this ball carried both light and heavy pocket hits for me.  The second set of games, I moved deeper inside playing around the 15 board and swinging the ball out to 8 board.  Keep in mind that our house patter has an out of bounds past the 5 board.  The rumble did exactly as I expected it to do.  I was able to get great length throughout the dry portion of our lanes and still get a great snap to the pocket.  I did hang some corner pins, but that is expected with our pattern due to the massive backend in the middle portions of our lanes.  I was able to get this ball a bit wide and still have recovery to the pocket as well. 

Compared to the wrecker, this ball is much more controllable and forgiving. 

Pro shop reaction:  I cannot keep this ball in stock.  As soon as I put one on display, it sells within two to three days!  This ball has a fantastic look as well.  All of my rumble customers agree that this ball is much stronger than they expected.

Recommendations:  I would recommend this ball for any bowler ranging from beginner to advanced bowlers.  The rumble would be a great benchmark ball to start out with.
