Weight: 15 lbs.
Pin Length: 3"-4”
Drilling: 60 x 5 1/4 x 30 with no hole
Pattern Length: 41 ft.
Pattern Volume: Medium
Pattern Type: THS
Right Handed

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.

I have found this to be to snappy in the back end, middle lane. Will need a surface change or polish for most bowlers. Great ball

Layout is pin under ring finger 4” from my pap; cg is shifted out with a balance hole.

I am a left handed tweener with a 325 rev rate.

Having the combination of solid coverstock and symmetrical weigh block has always been one of my favorite ball motions. The rumble definitely continues this trend for me. It clears the front and still has enough energy to get through the pins. I have also taken the surface down to as low as 500 grit, and the coverstock can definitely handle it. I can use the ball on house shot conditions or tournament play.
For the price point, can’t beat the value.

Rotogrip Rumble Review

Benjamin Goede (Storm/Rotogrip Amateur Staffer)
Ball Weight: 14LBS
PAP: 4 inches over X 1/2 up
Layout: RICO drilling (Pin in palm, 45 degree swing, hole 6 3/4 down

I chose the RICO drilling for this ball because I wanted a solid that was smooth and took away the early hook on medium - medium dry lane conditions.  This is ball is strong.  For the price, it is the most ball for the money.  It has become my first ball out of the bag when I bowl a tournament where the oil pattern has not been posted.  The roll of this ball reminds me of the shooting star but overall it transitions a few feet earlier and is overall 2-3 boards stronger.  I've found I really like this ball when my disturbed has become too much and I'm not in need of more length from a pearl.  It works really well on THS for bowlers who want some help with hook, without it burning up the lane to quick for others.  This is a great ball for bowlers who want to take their game to the next level and for all serious bowlers who bowl tournaments.  Lets get ready to RUMBLE!

Type (THS, Sport Pattern etc):THS


Simply the best ball on the market in that price point. This ball reads the mids and makes a strong continuous move to the pocket. Don’t let it fool you..Out of the box it seems a little weak, but the more you throw it, the more it seems to want to hook. Great ball for the person wanting to buy 1 ball and have it last. One ball every style of bowler needs to check out. “Lets get ready to rumble”
