See profile for stats.

Lay Out: 4.5" from PAP at 75* PAP angle and 60* VAL angle. The pin ended up under my ring finger. No weight hole.

Surface: I left it in box finish.

Purpose: I wanted to fill a gap for a benchmark type ball in my arsenal.

Lane Condition observations: I have mainly thrown this on our house pattern both on the fresh and on broken down second shift conditions. The house pattern at our center does not hold up in the heads for very long, so I am able to stay with this longer by shimming inwards. The cover/core combo gives a very smooth read of the condition. I also noticed that the surface did not overreact off the dry boards, but made a nice smooth arcing shape. This ball reeks of control and may get smoothed up with 4000 sa-air and moved into that spot in my arsenal.

Final Thoughts: I anticipate that this will be a fantastic "read" ball for me to start with and make moves with. It also gives me a duller surface control ball that can be taken down with abralon to throw on flatter/longer patterns where keeping my target in front of me would be a plus.

Here is my review of the 2nd RIOT I drilled:
 30 x 3-3/8 x 70 medium size hole on P2- serial# 10RRTB04E033G
This one is much smoother and not as a BIG HOOK as my 60x4x70. A lot smoother length and hook wise. Don't get me wrong, it was not flat, just more of a good "rolling" ball. Used it for about 12 games on THS, and 4 games on our flat tournament shot. This layout performed much better on the tournament shot, less overreaction. Loved it... Feels real good and made my confidence better on the tournament pattern.
Thanks to Mike Sinek for the layout recommendations.

Using the Ultimate Vision solid coverstock (2000 abralon finish) with a new medium core (2.58) and medium differential (.40), Roto Grip has created a Riot in the bowling ball industry. With a slightly stronger Rg than the Planet series, the Riot is a ball for medium to drier patterns. For PBA patterns, with proper layout, a stroker will find the Riot to be a very good choice on the 37' Viper and 39' Chameleon. The ball has one of the best mid lane reads in the Roto Grip line.
 
I drilled the Riot with a 55 degree pin/pap, pin 4 1/2' from PAP, below my ring finger, with the cg out and a 7/8" weight hole drilled on a straight line 4" from my grip center to create some hook/stop on the back end. I used the ball in a PBA Sr Regional on the 37' Senior pattern on Brunswick synthetic lanes. The Riot did nothing until it reached the midlane. At that point the ball made a smooth move to the pocket and set up nicely. Carry was excellent. I was able to use this ball for 6 games of qualifying before changing to a ball that would get down the lane as the lanes had started to hook earlier as the pattern broke down.

The new release from Roto Grip on the dark star and riot are awesome. The combination that both balls bring to the table are well balanced. From the cover stock to the weight block makes these balls my first choice out the bag.


Riot-This ball is almost a mirror image of it's fellow brother dark star. Having the same weight block and ball dynamics in it's characteristics, there are still some differences. While keeping close to the same layout as the dark star the riot for me rolls smooth through the front part of the lanes and still stays on course to the break point. How ever the entire roll of the ball from start to finish creates more over all friction then the dark star. So while the riot rolls through the oil, it still moves towards the pocket with a smooth heavier roll due to it's solid reactive cover stock. These two balls are really ahead of there competition for there performance level. Layout for dark star- pin above bridge, cg 2” right from center of grip. Balance hole on val in pap. Riot layout pin below bridge cg 2” from center of grip. Balance hole on val in pap. I will have a video link on here tomorrow.

Once again great job Roto Grip.

Ball specs – 15 lbs 1 oz, 2.93 top weight, and 3.00-inch pin.

The Riot was drilled with a 4.5-inch pin, 60-degree drill angle and a 40-degree VAL angle.  This put the pin just above the ring finger with the CG bumped to the right about two inches.  This layout did not require an extra hole with the ending positive side weight being 15/16ths.  The cover stock was left OOB.

I threw the Riot and Dark Star on a fresh, softer oil pattern.  The Riot, with its dull cover, started up about two to three feet sooner than the Dark Star.  The Riot proved to be a stronger ball than I expected and provided a sneaky strong, smooth and predictable motion on this medium pattern.  Hit and carry were very good for an entry-level piece. Track flare was in the four inch range and the rings were fairly close but not over lapping, similar to the Dark Star.

Using an existing cover stock with the new Photon core (.040 differential) allows the Dark Star (and Riot) to fill the gap nicely between the stronger Nomads and the weaker Planet series balls.  The Riot will make a nice addition to anyone’s arsenal providing a similar but overall stronger ball motion than the Pluto.

Riot

15lb 4oz with 3 oz Top weight. 3-4” pin

Drilling: 4 X 4 with a 27/32 weight hole 1” down on VAL from pap

Finish: 2000 abrolon/magic shine polish


SMOOTH, SMOOTH, SMOOTH….. That’s all I can say about the Riot, this ball is so smooth throughout the lane it’s amazing. I have yet to find a condition were this ball jerks off the spot.  I added polish to mine to get the reaction under my Nomad Solid, it fits really well in this category, and it is about 5 and 3 weaker then the solid Nomad. For the money, this ball is a winner no doubt I don’t think there is a ball at this price point that can compete with the Riot!

Hello everyone and thank you for reading.  THANK YOU ROTOGRIP.  Awesome addition to the line.  If you are just starting out with high ball speed or if you are looking for a great fresh short oil pattern ball this is it.  Here is what you all are looking for……   Drilled mine up with the same drilling pattern as one of my Nomad Pearls  which worked incredibly well.  Drilling pattern was 65 x 5 x 65 using the dual angle layout technique.  Here is our video so you may get an idea of reaction-- http://www.youtube.com/watch?v=xODtv9TGoQQ .  To keep things consistent we made surfaces on both bowling balls 4000 abralon.  This ball has given me a look in the track area longer and with a more controllable reaction on the backend on fresh and through transition.  The ball allowed me to move inside as the lanes broke down and still maintain an incredible carry percentage.  The backend move is controllable and continuous and the pin action this ball creates is unlike any other I have seen from a “lower end ball”.  This ball is anything but low end from what I have seen but definitely allows you to keep your feet and line further right(for a right hander).  The Nomad Pearl that I tested against with the same pattern can been seen on the video.  I am at least 4 to 6 boards right with my feet and 2 to 3 boards right with my target while testing and still maintaining excellent length through the front and GREAT HITTING POWER!!!!   Nuff said.   Keep the good stuff come RG!!!!!
