Roto Grip UFO Alert Bowling Ball Review

Thanks for joining us for another review, this one is for the Roto Grip UFO Alert.  We’re here once again at Royal Crest Lanes in Lawrence, KS on the house shot, all I have to do is send a text and they get us whatever we need, so thanks to Larry, Jessy, Rocky and the rest of the team, they’re a big part of helping us bring the reviews to everyone. 

eTrax Hybrid Coverstock

The details are pretty straight forward, etrax Hybrid or the Idol Synergy cover on the ET core from the original UFO, but with a small wrinkle, the Synergy was a half and half mix, half pearl, half solid, while the Alert is 2 parts pearl and one part solid.  Etrax hybrid is a bit stronger, earlier, and smoother than the pearl version that’s on the UC2, which is to be expected.  Cover designators really don’t matter unless you’re dealing with the same formula, so in this case it works out. 

ET (Equalizer Technology Core) 

The ET or Equalizer Technology core has a 2.52 RG, an .054 differential and an .016 split or intermediate differential in 15 pounds.  The RG is on the high side for an asym, but still on the lower side overall, and the cutouts in the bottom of the core are intended to mimic the effect of a weighthole. 

Angel’s Layout & Initial Thoughts on the UFO Alert

Angel’s layout is the same as always, 5 x 3 ½ x 3 ½, which puts the pin above her bridge and kicks the psa out.  The total package here is like a beefier Idol Synergy or a smoother UC2.  It’s not quite as round as the Synergy, but it’s more dynamic when it starts revving up.  Now I think it’s obviously less boomy than the UC2, but it splits the gap pretty nicely.  I’m not going to feature the original in this video because the hook potentials are so far removed, but the Alert has a very similar roll, round and firm but pretty easy to control.  Angel never got along with the Synergy, angle issues for days, and the UC2 can be too quick sometimes, so this one is finding a nice balance for her.  It covers a decent amount of ground, but it gets plenty of length, which helps Angel with her slower speed.  She doesn’t have to chuck it to get it down the lane, and she doesn’t have to dump it to keep it from checking too hard, it’s just a nice easy roll for her.  

UFO Alert VS RST X-1

Comparing it to the RST X-1, there’s a wrinkle here.  The RST is also a hybrid, but the formulas are pretty different.  The RST is the microtrax formula, which is a lot stronger, earlier, and smoother than the etrax formula in general.  The Alert rolls quite a bit like it, it’s just a couple boards weaker, much easier down the lane, and of course more responsive on friction, so I think these two will be better compliments than the Alert is to the UFO, with the UFO also being microtrax, but the solid version, it’s even stronger, earlier, and smoother than the RST, so RST is actually more of a ball down from the UFO, and then the Alert would be a nice step down from the RST.  

UFO Alert VS UC2

Comparing to the Roto Grip UC2, the balls have the same cover formula, UC2 being a pearl and the Alert being a hybrid, and while the UC2 has a lower split or intermediate differential, the Rondure core in the Rubicons has a lower RG.  Despite this, that core creates a lot of torque and shape, which the higher RG helps the ET core do, so the Rondure and ET cores feel pretty similar in strength and torque to me despite the number differences.  The UC2 is obviously sharper, the length is about the same, total hook potential is about the same, the Alert is just a bit slower and rounder.  

My Layout & Initial Thoughts on the UFO Alert

On the other side, I have the relationships the same.  I’ve slightly adjusted my asymmetric layout, instead of the typical 5 x 3 ½ x 2 ½, I’m at 4 ¾ x 3 ½ x 3 ½ now, which puts the pin in my ring finger instead of above it.  What this does is make the shape a bit more continuous and push the reaction a little further down the lane.  I’ve tested it out on a few other balls and even though it’s a relatively small adjustment, it’s fine tuned in the right direction.  The other layout was a bit too dynamic too early.  Despite familiar feelings from the core between the UFO and the Alert, this is so much weaker and cleaner of a cover that they’re pretty far removed from one another, I also have the RST X-1 pretty perfectly between the two.  Mine is a bit stronger than I was expecting, I throw the Synergy quite a bit here, and it’s noticeably easier down the lane which we’ll see here in a minute.  The Alert definitely revs well and punches firmly, it’s just a bit earlier and more dynamic than the Synergy which makes sense, it’s basically an asymmetric version of the Synergy and that’s what asyms do.  Where the Synergy prefers to stay outside 3rd arrow, the Alert is a little difficult to get down the lane from this straight with a good roll on it.  As soon as I start moving in, it’s the best of several different worlds.  It reminds me quite a bit of the Astro PhysiX actually.  It’s a clean cover, so I don’t have to fight it for length or shape, but I also find it to be a little slower and rounder than the UC2, which ups controllability a bit, while still generally having a rounder shape like the Synergy, just with the ability to move in and bend it a bit.  

UFO Alert VS Idol Synergy 

Looking at the Idol Synergy, it’s obviously easier up front, and that nice glide through the fronts and the clean and round move on the backend has yielded me quite a few big games and sets here over the last several months.  It’s just the easy button from 2nd arrow, which is lefty heaven.  Sometimes depending on the pair, the angles with it are a little tricky, so having something like the Alert to offer me the same general idea but a complimenting look if the Synergy isn’t quite it that night should make people hate bowling me even more.  As soon as I start trying to move in with it, I can make it work, but that’s just not its wheelhouse, so I have to do a bit too much with it.  

UFO Alert Compared to the RST X-1

Looking at the RST, the shapes are very similar, the RST is just obviously earlier and smoother.  They play in about the same areas, which is really anywhere on the lane I want them to.  The RST is flying under the radar, but is in my opinion very underrated or really more just overlooked.  The combination of strength, control, and shape through the pins that’s consistent across the lane makes it ridiculously versatile and in play quite a bit.  So where the Alert offers a zone compliment to the Synergy, it offers a shape and traction compliment to the RST.  If the RST is close but a little too strong or slow, the Alert is extra length and extra shape.  If the Alert is a little too long or over/under, the RST is more traction and control.  

UFO Alert Ratings For Hook, Length and Backend

As far as ratings go, the Alert gets an 8 for hook potential, a 6 for length, and an 8 for backend strength.  It’s a very well placed new option in the Roto line that offers a compromise and a compliment to several of the other balls in the catalog, and it releases on June 18th with the Dark Code.  It’s closest to the Zen on hook potential, the Phaze 3 on length, and the Idol Synergy on backend strength.  Select the next comparison you’d like to see from the links on the screen or scroll down to the description to find links to other choices.  Thanks for watching and may the strikes be with you.

Our obsession with helping players of all ages and styles conquer various lane conditions while abiding to forthcoming governing rules, led to the development and creation of the asymmetrical E.T.™ Core (Equalizer Technology Core) which features built in cavities in order to increase weight displacement after drilling without a balance hole to increase overall ball motion.

The MicroTrax (Micro Nanoparticle Traction) Coverstock offers the optimum balance of midlane traction and responsiveness to friction thanks the blend of nanoparticles throughout the coverstock. This formulation maintains its surface profile texture longer to ensure you get maximum performance while displacing oil at an above average rate compared to other coverstock materials on the market today.

Assembled for every bowler in the universe, the UFO™ Alert is here to help you navigate those Medium to Medium/Heavy Oil Conditions with ease. No matter your style, no matter your rev rate, no matter your speed, the E.T.™ Core (Equalizer Technology Core) with its built in cavities, is sure to create great overall core motion every time due to the added mass displacement when drilled. And we can’t forget about the eTrax™ Hybrid Coverstock which is made of 2 parts pearl and1 part solid. This cover combination aids in creating plenty of responsiveness to friction down lane without being too angular. Thus, making this combination of core and cover one of the most ideal options ever created for most any house type oil condition on planet earth.
