PAP-5 over and ½ up
Ball Speed: 15-17mph
Rev Rate: 300-500
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.

Lets talk Rumble. The Rumble is a very rolly ball for its price point. By tradition, the HP2 line gives me a better skid/snap reaction. However, I was proven wrong when I drilled this ball. The surface of this ball allows it to grab early and the low differential gives us the controlled motion down lane. So with that being said, if you are currently using a Disturbed and having a problem with the ball over reacting and reading the pattern too early, you should be able to step down to a Rumble and move a couple boards left and start turning the big wheel. Also, if you are throwing some Storm equipment such as a Reign of Power or an IQ Tour Solid, the Rumble will also be a great step down from these two balls as well.

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.

Bowling on my Wednesday league another 300 with the Rumble. Roto Grip is starting to take over Vandenburg AFB CA. Every night you will see either a Defiant, Deranged, or Rumble on every lane. Roto Grip is the best.

RUMBLE - Review
Date: 9.24.2013 Bowler: John Brodersen Location: Helena, Montana Pro Shop: JB's Pro Shop
"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.
