- Description: The NEW Late Roll 46 core was designed to provide maximum length with stable control down lane. This core will produce a minimal amount of flare and strong hitting power through the pocket.
The NEW 42L pearl reactive coverstock was created to combat lighter oil conditions. It allows the Scream to easily clear the front part of the lane – and look good doing it.
The NEW Scream was designed for those lighter oil conditions where you need a ball that provides you with great length and control at the breakpoint. It will react later in comparison to its battering mate, the Shout.

Ball specs – 15 lbs 3 oz, 2.62 top weight, 3 1/2-inch pin.

The Scream, which is a polished pearl, was drilled using the dual angle method.  The layout is a 4 inch pin, 60-degree drill angle and a 30-degree VAL angle.  An x-hole was placed in the P2.75 location.  Using Storm’s layout terminology the layout would be 4  by 5 with a 2 1/8 pin buffer.  The cover was left OOB which is 1500 polished.  The color scheme of the Scream is bright and eye grabbing

The pattern bowled on was a 41 foot, 24 micro-liter broken down house condition.  I had used a Defiant Edge and a Berserk earlier and was playing around 22 with them.  With the HP1 Scream, I was able to move my feet 11 right and my target 5 right to get closer to the friction and get to the pocket.  The Scream was very clean through the fronts, cleaner than the Shout, on the broken down pattern.  The Scream made a much stronger move than the Shout off the friction into the pocket.  I would describe the move as a hard arc.  The hit and carry was well above my expectations based on my experience with the Roto Grip planet balls.  Compared to the Shout the Scream was a little longer and quicker off the break point.  The overall all hook was about the same as the Shout, just a different motion.

The new Roto Grip HP1 lineup of the Scream and Shout will provide additional ball choices and motions for those lighter oil or broken down conditions.

Scream--- 55x5x60 layout-box condition
Patterns tested on: THS on HPL, SPL, and ½ HPL and ½ wood, and Los Angeles pattern
The SCREAM worked well on the HPL and ½ and ½ surfaces on THS and LA pattern. The ball loves the lighter volume and lighter oil, when heavier oil is found; the ball tends to “give up” near the end of the pattern. This ball is great for lighter oil patterns and for slower ball speed users.  The ball likes the first few boards on the house conditions and I was able to point and play or play the channel and was able to strike at will with it. For an entry level ball, this ball is money!!!

Scream review by Storm/Roto Grip Staffer Garrett Richardson
« Reply #3 on: October 08, 2012, 11:45:25 PM »
Hand: Left
Ball Speed: 16-17mph
Ball Weight: 15lbs
PAP: 5 left 7/16 up
Degrees of Tilt: 17
Layout: 5 x 4 x 2 ½

The Scream is drill pin above the middle finger, cg kicked out with no hole. I needed something for when the lanes get really dry and not have to make a drastic move and lose the pocket. It is not a ball that you can stand left throw right when there is a good amount of oil unless you are a high rev bowler or if it’s dry enough. The lanes at my main center have pretty dry outside boards which is around 7 board and out to the 1 board. When I get to the dry weather it is swinging to the dry or going up the boards it does not give me and up and down read. Really consistent read all around. I am able to play in my comfort zone or even go up the boards and the ball does not over react. Nice control motion and when it hits the back end it doesn’t jerk like other pearl balls it is much smoother.

I compared it with my tropical heat hybrid and rising star, and I am able to stand 6 boards left with the Scream compared to the tropical heat and rising star which is great when the lanes get toasted and everything else is hooking too early. I kept the factory finish on it which is 1500 polished. With this new low end line for Roto Grip it gives the Roto Grip fan a great low end ball for dry lanes or if you wanna play straighter for the down and in bowler for a great price.

I am a bowler for Wright State University. I have had the Roto Grip Scream for about 3 weeks now and this is a fantastic ball. I have the pin above my middle finger and the CG to the right of my grip center. This ball is very predictable on a variety of lane patterns, is truly a weak ball, and hits like a tank! I have thrown this ball on two different 35ft collegiate patterns and on a burnt 40ft collegiate sport pattern, never did I not know what this ball would do. Roto Grip has a true gem in this ball and I can't wait to see what else they bring out in the future, because Roto Grip is truly "King of them All".

Length:36 Los angelas

Likes:smooth predictable down lane reaction with little overreaction

Dislikes:needs a couple of games prob some where around 10 before I trust it on a sport pattern, and also a few flat corners

Lay Out: 5" from PAP at 50* PAP angle and 45* VAL angle. Dual angle measurement would be 50/5/45. The pin ended up about 1/2" above my ring finger with the CG swung out from the ring finger. The 50* angle put the RG about an inch right of my thumb. I also have a weight hole 5" straight across the center line and down an 1". I also drilled the Shout with the same lay out to have a nice 1-2 punch.

Surface: I am box finish which is 1500 Reacta-Shine.

Purpose: I wanted to drill up this up to see what it rolled like and also to get it on the lane beside other pieces in my bag. I had a Dark Star that I really liked when I needed to control the breakpoint on shorter patterns. Plus we have a lot of friction to the right of 10 on our house condition right now. I was hoping this would let me start closer to there if possible for better carry potential.

Lane Condition Observations: I have thrown this on a couple of different patterns: Left over shot the morning after a strong scratch league and all night open play, and second shift of our normal league pattern. The second shift was following a mixed league full of plastic throwers and head pin hunters. All I can say is I love the reaction of this ball. Strong arcing almost skid/flip but predictable would be the best way to describe it. Our house condition is 38 feet on Brunswick Pro Anvil Lane. On the overnight leftovers, I had to start inside of 20 to find upfront oil to push this with and even then, it was still too early.  As long as I got it going with good direction and motion to my target, I had miss area right of the target by a couple of boards. I got to put it to use following the mixed league in front of us and this ball didn't disappoint. I got to try it on some fill balls. The back end is slightly stronger than the Shout.

Response to Friction:I would rate this a medium to faster response in box condition. The motion is archy almost whippy off the spot. The response time  might go down some with a smoother surface which make it just a little more less in the back than the Shout.
Other Ball Comparisions: I did get to throw it some side by side with my Fire Road and Shout. The Fire Road was much earlier and stronger on the back end. The Scream suprisingly was a little sharper off the breakpoint than the Shout. I was able to "chase it left" quicker with the Scream. My moves with the Shout were more 1/1 and moves were 2/1 & 3/2 with the Scream. I would imagine with all of the friction on our house shot, the polished surface of the Scream was making it change direction harder. The Scream looked like the right ball to step down from the Fire Road with and keep the same motion. The Shout was more of a controlled arc in comparison.
Final Thoughts: The Scream has the looks of a good skid/snap ball in box condition for when the fronts really go and you get pushed inside on your league shot. If the Scream is too over-under on the house shot, just slap a 4000 abralon pad on it and that should cut down on the skid some. I am interested if I will have to make some surface adjustments on shorter patterns to get it to slow down in the back end some.

Roto Grip Scream
« Reply #8 on: November 25, 2012, 12:23:46 AM »
  The Roto Grip Scream is in the HP-1 line.  The scream is a high RG and low differential ball, just what I was looking for the drier lane conditions.
I drilled the Scream 4.75 x 4.5 x 2.75 pin up.
The Scream is very clean through the fronts, and strong arc on back.  The scream doesn't have a skid /flip reaction, more of a hard rolly move off the spot.
I go to this ball when the heads dry up and I need some length..
For a entry level ball from RG the Scream is a great ball for the money.
Plus has great shelf appeal.

PAP 4 up 1 1/4

My Axis is 5 5/8 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.

Drilled the pin 5 ½” and the CG 5 ½” from PAP (pin down).

Oil is not its friend.  This ball is for less oil, slow speed bowlers or lots of hand.  The ball gets great length before its move.  It can be used on the driest of conditions or when the heads are gone.  My ball rolls too early on dry heads so this is the ball I will go to later in the day.  Also I know several people that struggle with low speed and house shots are just too dry for them and now they have an answer without having to go to plastic.  Great ball for slow speed or lots of hand.

Thanks for reading all and as always the video to go along with this review can be found here :

Rotogrip Scream is here.  Great looking ball, great price and fantastic performance.  Went with my favorite layout here 65 x 4 3/4 x 65.  I was able to use this on all transitions while using the Shout and easily got the ball to the pocket when the lane seemed to go away.  The core is modified from the Rising Star Shooting Star and Shatter to allow the ball to conserve energy further down the lane.  Add in the pearlized coverstock and you have a long straight ball through the front with a little strong arc on the back part of the lane.  The more you rev it up the more it kicks. I have left mine with the Box surface as I will be using it more for when lanes get some extreme breakdown.  Rotation is easy to see and when the roll picks up when encountering friction you will recognize it.  The ball transistions extremely well into the pocket and shreds racks with ease.
