I would not consider them to be RG's version of the IQ tour editions... also you seem to be focusing on undrilled core numbers when the coverstock is the main reason the core will get to have any influence on the ball motion.  Nevermind the fact that you probably don't bowl with undrilled bowling balls...

I would doubt that Utah would put as strong of a cover on a ball that retails for $50 less than an IQ Tour...

How were your IQ TE's drilled?  Dual angle layout would be nice but, pin to PAP distance and location/depth of extra holes is useful as well.

my rumble is oob 2000 abralon, i drilled it stacked over ring no balance hole.  I have used it on a heavy oil 42 ft house pattern.  on this particular shot it shines. For a dull ball this ball flips.  It ignores the heads but once it sees friction it goes right for me.  I als bowl in a light volume house shot league that have very sharp backends.  Cant use this ball there this ball is way to strong.  This ball in oob conditions is alot stronger than one would think. i am looking forward to the uproar.

Drilled a Rumble Sat.  My stats. in profile.  Used it on two conditions both 39' one house shot about 10:1 and a modified White 39' 6:1. 

Rumble is all about surface.  A true medium benchmark ball for me at OOB 2000.  One observation is that most equipment for me with surface on higher friction lanes tends to puke and burn up NOT the Rumble it's higher Rg and low total diff plus my layout got it down lane and ball motion is a longish heavy roll no flip.  Quite the control piece without the control layout. 

Uproar will be an interesting pearl piece with same core.  I see the Uproar as a light-medium ball for me under the Rumble.

RG seems to have hit on some winners the past few years.  Lots of Disturbed, Deranged, Wreckers, Defiant line in my area.

73*(PAP-pin-PSA)x4.50"x38* with ability to put in Motion hole

It looks like you layed this out for a Motion Hole. 

I guess I got off topic a little.  How is Roto Grip envisioning customers using these  balls?  Wouldn't the Rumble react a lot like the Disturbed? 
Or are they just giving the consumer a similar hook shape for less money than the Disturbed? 

It seems like Roto had a specific purpose in mind when they designed these balls.  They are medium high RG with lower Diff.  What condition were they aiming these balls to be used on?

Yes if I wanted to go that route...so far I like what I see without the Motion hole.  We'll see.

Not sure but I would envision much the same ball motion as a Disturbed.  There are vids out here that compare them.  For me cost doesn't mean better scores.

Medium to light-medium for me as a bowler that has the ability to play different trajectories.

Scott:  I see.  This gives Roto 2 balls in the lineup that are more control-ish to handle the over / under condition?  Now that you put it like that it makes a lot of sense.  These balls should be usable on a wider array of conditions than the Storm Breeze's would be.  The Breeze seems to be squirrely to a lot of people. 

So Rumble/Uproar would be good choices for when you are shooting on a THS that's giving you a lot of over/under?

Rumble in OOB definitely needs to be played by the majority of us inside out on house shots.....unless speed dominant lower revs.  You can see my layout is not control but surface leads to more control.

Uproar being a more skid flippy pearl not sure I would say that it will control side to side friction.  Pearl would allow from front to back early friction.  Heard today that RG will be dropping Shatter so Uproar fills that slot though Uproar is less total diff.

I'm throwing a Disturbed at 3000 on its great on my ths. I was thinking about grabbing a rumble and possibly polishing it.

What RG is trying to do with their line up is create a similar reaction with stronger or weaker covers, making it easier to transition from ball to ball in their line up. RG is to Storm as Brunswick is to DV8 (Big Cores to Smaller Cores). RG gives the length of Storm without the huge amounts of flip. From what I've seen and thrown, The Low End line has a core similarly shaped to the Spit Fire from Storm. They, pretty much are the same balls as the Star series of balls and roll really well on a wide variety of patterns. The Rumble is going to be a great THS Benchmark for most and that Core is great for the Motion Hole as I have a Shatter with the MoTion Hole. I have loved the Shatter and Wrecker and will have a Rumble by the end of the month with a Motion Hole to compliment the Shatter with Motion Hole. These have been some of the most driller friendly balls ever.

The Disturbed is an Incredible ball for oil (which I have owned and loved). The ball picks up early and rolls heavy, and strikes.... A LOT!!!!! The Deranged is the Pearl Version and rolls equally as good. They are have slightly higher core numbers because the covers are so strong.

Overall, I think the Rumble is going to be another great solid that will be forgotten like the Riot, Horizon Solid, and the Outlaw which strike a lot and because they don't flip. My suggestion, get one or two while you can. For the price and drill versality, you can lose.
