900Global continues the success of the Zen bowling ball line with a urethane version. The 900Global Zen U combines the reliability of a solid coverstock with the consistent nature of a urethane coverstock. The S35 Urethane+ Solid coverstock has a quicker response than most urethane covers and is wrapped around the large and aggressive Mediate LD symmetric core. This high-performance bowling ball is best used on shorter patterns and will continue the unique shape that bowlers have favored from the Zen ball line.

Zen U Review
« Reply #1 on: February 12, 2023, 12:33:32 PM »
Ball Specs:
Global Zen U
S35+ Urethane Solid Cover
1000 Grit Sanded
Meditate (Symmetric)
Layout 4.5 x 4.5 with 2” Pin Buffer

Bowler Specs:
Right Hand. PAP 5” Over 1/2 up
Rev Rate 300. Tilt 20. Rotation 50.
Speed at release 17

I am a big fan of the UC3 but I rarely can use a Pitch Black due to my lower rev rate and higher volumes of oil I bowl on. When I heard about the Zen U, I was very interested to see how it would roll. The Zen U has one of the new blends of Urethane that gives more hook potential to traditional urethane. The Zen U hooks more than I expected and was extremely smooth. It fits between the Pitch Black and UC3 in total hook. I would call this a medium to dry lane ball. I really like how this ball blends out the over under and wet dry lane conditions. I do sacrifice some carry with this ball but it’s hard to miss the pocket with it. As the Zen U lane shined a bit for me the carry did get better. The Zen U has been selling really well and the higher rev rate bowlers all seem to be having very good success with it. I would recommend this ball to anyone who wants a stronger than traditional urethane reaction and smooth control. The Zen U would fit great in a tournament player’s bag for short patterns or very challenging lane conditions.

The Zen U is smooth and controllable.
The Zen U may cost some corner carry but gain control of the pocket.
The Zen U cover is an upgrade on traditional urethane.

900 Global Zen U

The new Urethane ball in the 900 Global line is the Zen U.  I drilled mine with a 4 inch pin, pin up. 4 x 4 x 2.  As a SPI staffer I really felt like there was a gap between the Storm Pitch Black and the RG UC3.  As the pitch black was pretty early, and slow response down lane.  The UC3 has an asymmetrical core is really strong downlane.  So thanks to the R&D at Storm the Zen U fits right in the middle.  As it has a symmetrical core with a modern day urethane cover. So the Zen U has some very good motion downlane. Its not a lot but for urethane it is.  So we actually have some shape downlane with a urethane ball.  This is a great addition to the line!

Zen U is the one for U!

Bowlers Info: RH tweener, PAP 4-5/8 x 3/4 up, 380 RPM, 13* of Axis tilt, 60* of Axis Rotation

Ball Layout: 45 x 4 x 30
VLS: 4 x 4 x 2

Finish: OOB

The Zen U is the newest urethane piece by 900 Global.  I drill all my urethane pieces pretty strong with 4” pins above the ring finger.  For me this urethane provides more backend motion than any other urethane I’ve thrown.  Pitch Black is the soonest, then my Fast Pitch, then Zen U.  Zen U probably has the most backend of these three where I feel I can stand left and throw it right to the friction, almost reactive type reaction.  So if you’re looking for a different motion as a urethane option, give Zen U a try as this definitely has a look all it’s own!

Brand new Urethane! I am extremely excited by the newest release from 900 Global. I am a big fan of the Pitch Black and the Zen. This combination brings them together. The Zen U features the S34 Urethane+ cover with the Mediate LD Symmetric core. The Mediate core was featured in the original Zen, however the Mediate LD has a less dense core to help give that traditional urethane feel. This ball is a great bridge between my Pitch Black and the UC3. This ball will get a lot of play time on a multitude of patterns, especially when you want to control the pocket and the Pitch Black isn’t shaping the correct way. I will definitely be bringing this ball with me wherever I go, make sure that you go out and get yours today!

Lane Condition
Length: 40
Volume: Medium
Type (THS, Sport Pattern etc): THS

The Zen U is a mixture of Urethane and Reactive which makes it unique and very good. As I am a fan of the Pitch Black and Zen, these are very comparable once you’ve seen both motions. It reads the front motion like the Pitch Black and the down lane motion like the Zen. If you plan to use the Zen U on shorter patterns, I recommend using more surface or wait till transition after the Pitch Black. Zen U is the new future!

Zen U Review
« Reply #6 on: March 12, 2023, 06:20:15 PM »

Length: 40ft

Volume: Medium

Type (THS, Sport Pattern etc): THS


Dual Angle Layout: 50 x 4 x 45
Storm Vector Layout: 4 x 4 3/8 x 2 5/8

Likes: This ball was the perfect compliment to the UC3 and Pitch Black.  I’m not one to throw urethane too often but when I do the Zen U is now my go to ball.  This ball is super smooth and controllable.  When the UC3 is too much, but the Pitch Black is not quite enough, this ball will be the perfect filler.  When you need to keep the ball in front of you this is the one to accomplish that.  The Zen U is the best comparison to the Purple Hammer that SPI offers. 

Dislikes: Not a huge urethane fan so I'm not able to throw it frequently but when the need is there, this is the one.

900 Global Zen U Ball Review

Bowler Stats:
Speed: 15.5 MPH
Rev Rate: 300 RPM
Tilt: 3-5 degrees
Axis Rotation: 60 degrees
PAP: 5 ⅜ over 1 ¼ up

Layout: 41/4 X 41/4 X 2 VLS

Video Review:

Having a lower rev rate I do not use urethane a lot. I drilled a UC3 before the 2022 PBA Senior Tour just to have it in case a urethane option was needed on the Del Ballard 36’ pattern. With the Zen U ball motion fitting in between the weaker Pitch Black and stronger UC3, I wanted to see what shape the Zen U would give me. For me this urethane option does just that. It is not as early as the UC3 but has a smoother shape to the pocket down lane than the very slow shaping Pitch Black.

In my video ball review I did use it at a center that has a lot of friction and with the out of box surface. If the scenario calls for me to use the Zen U, I will need to add more surface to the ball so the continuous shape it makes lasts longer due to lane shine.

For the upcoming 2023 PBA 50 Tour we will be bowling at Sam’s Town in Vegas and on the Del Ballard pattern for the World Series of bowling so the Zen U will be in the bag just in case urethane is in play.

The Zen U is another entry in the evolution of the urethane bowling balls of today, as they continue to experience a renaissance in the bowling world. As more and more urethane balls are introduced, they seek to stake out a particular spot in the market, and I think the Zen U certainly has done that: a urethane ball that creates a little more backend reaction than a urethane ball traditionally would. That allows this ball to be used at slightly different times than other urethane bowling balls. When other urethane balls would hook too early and lose energy, the Zen U can continue to be used. With that being said, the Zen U is still best used on medium to light sport shots where there is still some oil in the heads, or for 2 handers on over/under house shots.

The Zen U is a new Urethane bowling ball from 900 Global. This new offering features the new Meditate LD core as well as the all new s35 Urethane+ cover. This combination of cover and core is designed to provide the bowler with control on very short and or over-walled patterns. The numbers are 2.56 Rg with a 0.027 diff in 15lb bowling balls.

I drilled my Zen U with a 3.75” pin distance and a 1.5” pin buffer. I wanted to try and maximize flare as I don’t have an ultra high rev rate, and to also compliment a Pitch Black with a very similar layout. Oftentimes during regional events, there is so much oil on the lanes on these shorter patterns that I just don't have enough hand to maximize the mistake room that is built into the patterns that higher rev rate bowlers can generate. My Pitch Black is very close early on when the lanes are fresh, but as the day goes on, I need a little more all around ball motion. This Zen U makes me excited to see regional play again, and hopefully some short high volume patterns.

I am looking forward to this upcoming tournament season, and being able to use the Zen U. Lower left to right ratio patterns with high volumes lend to bowling balls with hook and control. Having the Zen U in my arsenal is a must. Thank you for reading my review of the 900 Global Zen U.

900 Global Zen U Ball Review by PJ Haggerty

As we all know, Urethane continues to become more and more relevant in todays game.  The newest addition to the 900 Global Line is the Zen U.  The original Zen is still a home run in the current line, so our wizards in Utah used the same core (Mediate) and wrapped the Zen U with the s35 Urethane+ coverstock to give us a winning combination.  I’ve had a ton of success with the Zen U on multiple patterns and it’s earned a spot in my tournament bags.

I’ve drilled two so far but have had a lot of success with one of them.  This one is mapped out as 5 x 3.5 x 3.5.  This puts the pin below my bridge with a good size shift of the CG.  Comparing the Zen U to the Pitch Black, I have this one cleaner and more responsive down lane.  When my Pitch Black is too early in the front part of the lane, I’ve had success not moving my feet and going right to the Zen U to keep my angles in front of me.  If you’re doing to drill this ball, expect a quicker response time and more down-lane motion that previous Urethane balls.  It’s been great for blending out those wet/dry patterns and still keeping an extremely smooth motion.

Go drill one!

The 900 Global line introduces its newest urethane entry, the Zen U.  The Zen U features the all new S35 Urethane Plus coverstock, and the highly successful Meditate symmetric core.  The Zen U in 15 pounds features a RG of 2.56 and a differential of .027.  I drilled my Zen U 4 x 4 x 2, just a basic drilling which puts the pin above my ring finger.  The Zen U is not your grandfather’s urethane ball.  The Zen U reads the lane early just like most solid urethane balls, the difference with the Zen U is the continuation of the back of the pattern.  Where most urethane balls just keep going forward, the Zen U definitely has a more arcing backend motion.  As I do not drill many urethane balls and this is the first Global urethane I have thrown, it is hard to compare them.  However, I can say that I have drilled a Pitch Black and a Pitch Purple.  For me the Zen U fits right in between these two.  It reads early like the Pitch Black but has a little more left on the backend but not as much as the Pitch Purple which for me was more like an entry level reactive reaction than a urethane reaction.  The Zen U will be a great go to ball on the short sport patterns or a lighter oil condition where you are looking for a controlled reaction.  This ball does not lack in hitting power for a urethane ball.  Being able to stay right, I was able to throw messengers at those “urethane” corner pins that stayed standing.

Specs: 35+ solid urethane with the mediate LD core - finished at 1000 grit out of the box
Layout: 45 x 4 x 45

When making a decision to drill a new urethane ball, the 900 Global ZEN U was a “no brainer” for me. Using a Strong pin to pap drilling so that I can compare to prior urethanes from Storm like the Pitch line. The Zen U fits right between the Pitch Black and the newer Roto Grip release, the Rubicon UC-3. The Pitch reads for me too early and the UC3 with similar went longer and flatter on the house pattern that I was practicing and testing on. I bowled on a fresh house condition of 46ft with SPL panels, knowing not to expect a ton of recovery, but I was ultimately surprised by how the ZEN U performed. Cleaner in the fronts and still saving power to hit the pocket without urethane typical urethane deflection and leaving corner pins. For my next adventure, I ventured to a bowling center near me where the center takes you back to the heyday of bowling. The wood lanes are pristine and very playable, I used the ZEN U there in practice time and in a local tournament. Where I found I had the best reaction out of the bowlers using urethane balls, the pearls were skidding a little extra long and the Pitch Blacks were burning up and hitting the pockets flat. For those league and tournament bowlers that want to invest in your performance and game, don’t shy from the GLOBAL ZEN U!

Holy cow! This ball is unlike any urethane ball on the market. The Zen U makes that classic urethane shape will being able to handle considerably more volume than balls like the Pitch Black and Fast Pitch. As someone who isn't a big fan of traditional urethane, this ball is extremely promising, as i can play up the lane like with the Pitch Black, but if I need to rotate the ball more and shape it, the Zen U can handle the extra angle/volume in the middle part of the lane. If you don't think urethane is for you, the Zen U is the exception!

Ball Specs: Global Zen U
Cover : S35+ Urethane Solid Cover
Finish: 1000 Grit Sanded
Core : Meditate (Symmetric)
The UC3 has been one of my favorite urethane balls to ever be released but sometimes it can be a bit too strong. Typically I would go to my Fast Pitch, but not the same motion and a big step down from the UC3, enter the Zen U. The Zen U fits perfectly in between the UC3 and Fast Pitch. The Zen U is a perfect mix of smooth and control. I do not throw urethane much on league but when the lanes start to "cliff", the Zen U is the perfect combatant. It is strong enough to hook in the oil, but also has a controlled reaction off the dry. The thing that impressed me the most, was the corner pin carry. With most urethane, you sacrifice carry for control, but with the Zen U you do not have to make that sacrifice.
The Zen U was another great addition to an already great ZEN line.
