    Layout: 35 x 4 ½ x 70 The 900 Global Zen Master is a true example of how influential the coverstock is on the reaction of any particular bowling ball; the original Zen is an aggressive skid/flip ball, while the Zen Master is early, smooth, and predictable. Both balls utilize the same core, but the cover on the Master is much earlier and overall more aggressive. The Master is excellent on fresh, heavy, or long oil patterns. The massive amount of midlane roll that this ball boasts helps it to dominate those patterns. The Zen Master is too aggressive to use on anything less than medium oil, though the Zen and Zen Master combine to create a 1-2 punch that covers everything from heavy to medium-light conditions.

    The new Zen Master is exactly what I needed in my bag: a stronger Phaze 2. This ball is the perfect step down from the Reality or RST X1. The Zen Master comes with a 3000 abralon finish, but to me looked and rolled like it had more surface than that. Keeping this ball at box finish, it will be able to combat heavy oil patterns with no problem. When it lane shines, it becomes more similar to a Phaze 2 and works well when you need to blend the pattern without too much down lane shape. I like this ball with more shine on it, so for me it has kept getting better with time. I am definitely going to drill another Zen Master pin down, it is that good!

    Since the announcement of this ball, I was looking forward to getting a chance to see how much stronger this one was to the Zen. I drilled this the same as my favorite Zen with a 5 * 4 1/4 * 2 layout. Using this on a slightly used house pattern, I could really see the difference in the cover between this one and the Zen. The Zen Master started up about 3 feet sooner for me, which was expected, but even with the strong cover and the fresh surface, the Master never got to a point where it quit. Where I see myself using this are on high volume - medium to 44 foot patterns, and I do see this being a good option when the lanes get super cliffed to blend out the lane. Another great product from SPI in the 900 global line.

    900 Global: Zen Master Coverstock: S77 Response Solid Finish: 3000 Grit Abralon Core: Meditate Symmetric RG: 2.49 Differential: 0.051 Layout: 70 x 5 x 40 Tester: PAP 5 1/2 R, 1 1/2 D Review: The Zen Master features a solid version of the S77 Response cover combined with the newer symmetric core that was first featured in the Zen. The solid version of this cover will provide a round continuous reaction in the 800 Series line. For me, the Zen Master is the first symmetric out of the bag and provides a nice 1-2 punch with the Zen. For the video review, I tested the Zen Master on a 43 foot typical house pattern. This ball was very easy to read as it transitioned down the lane and as with the Zen line in general provides alot of miss room to carry pins. One tip to consider, depending on speed and rev rate, is to allow the Zen Master to get some lane shine on the coverstock. If you typically have trouble getting strong solid coverstocks through the front part of the lane, do not hesitate to try this out for the first several games. Grab the 900 Zen Master today! Also, be sure to watch the full video to see a quick reminder to stock up on kinesiology tape. Michael Slatky 900 Global Staff Member York, PA

    I drilled my Zen Master on the weaker side, with a 70x5x80 layout. It is an excellent benchmark piece. My first set on the lanes with it ended up being an 811, moving a total of 3 and 2 left the entire night. Smooth and continuous as any symmetric solid should be. Gave me more overall than the Phaze II. The 3000 finish ensures it won't miss the brRead more about review stating Excellent Benchmarkeakpoint, but won't hook too early before it gets there. What impresses me is the ability to stay in it for longer than one game before needing to ball up or down. Another great versatile piece of 900 Global.

    900 Global Zen Master Cover: 3000 S77 Response™ Solid Reactive Core: Meditate™ (Symmetrical) Color: Magenta/Black/Green Review: I was very excited for this ball after how much I loved the original Zen. The Zen Master has quickly become my benchmark ball that I tend to use early and often either at league or at tournaments. This ball is great at storing energy until it hits the pocket. The smooth motion reminds me of the reality but with the Zen Master I can play a little straighter early on. But don't get me wrong this ball also allows me to move left and swing the ball when needed. I have even added a little polish to this ball and still get an excellent ball motion that stores energy until hitting the pocket. This is another great piece for anyone of any skill level to pick up. If you liked the original Zen, you are going to love what the Zen Master can do. Go out and get you one today!

    Layout 60 x 5 x 70 After the success of the Zen, the Zen Master has been long awaited in the 800 Series line as the replacement for the Aspect. The Zen Master certainly lives up to its hype. It's strong in the front part of the lane and continues extremely well in the backend. Comparative to the Reality, the Zen Master is slightly cleanerRead more about review stating Zen Master while being about 4 boards weaker in overall hook. Compared to the Zen, the Master is earlier and smoother while being about 5 boards stronger in overall hook. My pin down drilling is great on fresh House and Sport Patterns for its control and predictability. A pin up version of the Zen Master will give a much stronger backend motion if you prefer that motion. Compared to the Aspect, the Mediate Symmetric Core of the Zen Master is earlier rolling on the lane. The two balls have the same S77 Solid coverstock but the Zen Master will give more midlane roll and more hook potential. With my higher rev rate, the Zen Master works great for me on the fresh house pattern or sport patterns with higher volumes of oil. The versatility of this ball will allow me to stay in the ball longer as I have to move more left on the lanes during transition. Adam Chase Storm Staff

    Global Zen Master Ball Specs: Cover stock S77 Solid Reactive Meditate Core (Symmetrical) Purple /Green / Black Finish 3000 Sanded Bowler Specs: Right Hand. PAP 5" Over 1/2 up Rev Rate 300. Tilt 20. Rotation 50. Speed at cameras 15.5 Review: The new Global Zen Master is a Solid version of the Original Zen Bowlers has been asking for. The Master is a strong symmetric and I really like it but for me it did not hook as much as I thought it would. It also did not wow me like the original. That being said it is a very good ball and I have shot some good sets and have struck a lot with it. When we did the video I struck 9 out of 10 times and we only kept 6 shots for my son who puts the videos together. The Zen Master provides a nice roll through the front of the lane with a predictable move on the back end. The Master fits under my Proton but above my H.B. Intensity in total hook. The Master and Reality are pretty close in total boards for me. The folks we have drilled the Zen Master for are giving very positive feedback on this ball and their scores with it. I like the way I can stay with this ball through multiple games before I have to ball down. My adjustments are slower than and not as large as when I use a strong Asymmetric ball. This ball seems to roll well regardless of the layout put on it. I feel it is a nice entry into the Medium to Medium Heavy Ball market. Summary: The Zen Master is another very good ball by Global. The Ball reads wetter patterns very well. The Zen Master has a strong predictable motion.

    Master of the Zen The 900 Global Zen Master was the most anticipated ball to the start of the fall season. It has lived up to it for sure! It is here to compliment one of the most popular 900 Global balls of all time, the Zen. This ball has the value of any high performance ball. I drilled mine strong with 4x4x2. If you like the Zen and want earlier midlane roll, this is it. The S77 Response solid cover reads the oil well and produces nice backend motion with a solid roll thru the pins. If I need more length, i switch to the Zen to get down the lane longer with the same backend motion. If it seems to be too much too early, you can also shine it. That always gives me the length I need to get thru the front part to save more energy on the backend. My PAP is 5-1/8 and 1/8 up. Usually around 15-16mph, I'd probably be classified between and tweener and cranker.

    900 Global Zen Master Cover: 3000 S77 Response™ Solid Reactive Core: Meditate™ (Symmetrical) Color: Magenta/Black/Green Review: Can you say ball of the year? There were very high expectations for this ball due to the high demand of the Original Zen. This piece did not disappoint AT ALL! We love strong symmetrical solids. For high speed and high rev players like ourselves, this piece works great, giving us continued motion and contained energy all the way through the pins. The Zen Master has similar ball motion to the reality, playing a few boards to the right. If you are starting out with a strong Asymmetrical piece this ball would work well as a transition in between that and something similar to the Burner or in the HP2 or HP1 lines by Roto. We anticipate keeping this ball on our shelf in the shop for a while. Kyle & Joel Johnson 900 Global Pro Shop Staffers joel@parklanes.net kyle@parklanes.net www.900Global.com #GoGlobal

    Compared my Zen Master up against my Phaze 2 and Axiom. Definitely was earlier and smoother for me then both. That being said I believe I'm going to like it the most. That's crazy to even say with how much I like the other 2. The early motion while still creating as much continuation as this ball has in the back is going to make it the 1st ball out of the bag for anyone that bowls anywhere with a decent amount of oil on the lanes.

    Last season the 900 Global Zen took the lanes by storm and quickly became a must have for every bowler. This season bowlers will have another ball they must add to their arsenal, Zen Master. The Zen Master features the same Meditate Core found in the original Zen but has the S77 Response Solid Cover. I was so hyped about this ball that I drilled two of them right off the rip, a pin down 4.5 x 4 x 4 and a pin up 5 x 5 x 3. Starting with the pin down one, this ball provides me a lot of early hook and a smoother motion where as the pin up one lets me open the lane up and is stronger on the backend. I have to say these two balls remind me a lot of the two Roto Grip Idols I had and I loved them, they made a great 1-2 punch on a lot of pattern lengths and volumes. Your not going to want to miss out on this ball, I will always have both these balls with me and I cant wait to use them more and more!

    The solid counterpart of the original famous Zen is here in the Zen Master. The solid version will provide plenty of overall hook to be used right out the gate. Meant for oil the Zen Master reads the body of the lane extremely well. The most surprising thing I found with this ball was it's ability to continue to hook down lane as the lanes transitioned and broke down. This ball is a little more overall than a Phaze 2 yet cleaner than a Axiom. As the lanes transition and begin to hook early we have 2 new options with the Burners; the solid and the pearl. If the back ends are crisp the solid will come into play to slow the ball down and control the back end. When a more skid/flip reaction is necessary the pearl could be utilized. The high rg low differential on these balls will provide plenty of control when there is a ton of overall hook on the lane front to back.

    The new addition to Global's 800 series line is the new ZEN Master.

I was very surprised by how strong of a Symmetrical ball this actually was. I picks up much sooner in the midlane than I anticipated, while still having that strong backend motion that I came to love about the original Zen. For me, this ball fits right between the Reality and Ordinance C4, and will be a great benchmark ball for upcoming tournaments.

    This ball loves oil! I rolled it, actually hooked a little sooner then the Reality, and a little more on the back end as well. BUT...the Reality has lane shine on it, I love that ball as well. I had the Master drilled the same as my Zen...because that is what I wanted. I love the Zen...and this is going to make me love BOTH balls now! When I started my feet were at 25 throwing over 3rd arrow, taking it out to 10-8 boards...and yeah! Its a great starting ball indeed! As the league went on (lol...yes I wanted to throw this ball!) by the 3rd game, standing 32 and hitting 4th arrow and taking it out to 12 board...make sure you keep your speed up, don't get lazy. (or you can change balls lol) I can't lose with this ball if there is a lot of oil on the lane, man it rolls so nice!

    Zen Master- Ball Specs Cover Stock: S77 Response Solid Finish: 3000 Grit Core: Meditate Symmetric Color: Magenta/Black/Green Layout: 65 x 5 x 45 RG: 2.49 Differential: 0.051 Intermediate Diff: N/A Review The Prime 800 Series greatly anticipated Zen Master does not disappoint and is an excellent complement to the Zen Pearl. The Zen Master features the S77 response cover combined with the Medtiate Symmetric core, which is the biggest core 900 Global has ever put into a bowling ball. This is the most aggressive symmetric ball I have in my arsenal. I tested this ball on 44 feet typical house pattern. As a mid to low rev player, I was able to move left of 20 and open the lanes up. I was also able to stand right of 20, play the track area and swing it outside of five with great success. Just like the Pearl the Zen Master strikes a lot. My ball's layout is 65 x 5 x 45. This is a great ball for all levels of bowlers. Order one from your local pro shop today! My ball review videos are posted on YouTube channel Stanley Waite.
