MEDITATE SYMMETRIC CORE

As mentioned above, the Meditate Core will provide the engine for the Zen Master. Expect to see a ball that revs up quickly and keeps going throughout the lane. Since the Meditate Core is so large, pin up or pin down layouts will not alter the RG/Diff values very much at all post drilling. House conditions and sport patterns alike will be no match for the Zen Master.

S77 Response Coverstock

The S77 Response Cover, in its pearl form, has more than proven itself. The Zen, while a dynamic and amazing piece, is still a polished pearl. When running into heavier volume patterns, nothing beats a dull solid. We have successfully optimized the cover into a version that will dominate medium-heavier oil patterns. The Zen Master will complement the asymmetric Reality perfectly to give the player a different shape on oily conditions.

Zen Master by Roto Grip Rick
900 Global Zen Master - layout: 65 x 5 x 25 - 1500 grit sanded
Ball test conditions: Practiced on 44ft THS on SPL and 46ft THS on older HPL
Looking to replace a piece I feel I have been missing with the OG Idol was removed from the current line, I was excited to hear that the Global Zen Master was going to be released… So, to do a real good comparison, I drilled it to my most favorite Idol layout I used in the past. 65 x 5 x 25. For me, it looks like a over the label drilling with a delayed pin. The colors match very well on the ball, a little phasing even helps it I think, able to see the ball change motion better than the one color solids like the OG Roto Grip Idol. Was a little early on reading the patterns until the ball took on the lane shine, which I guess I could have taken up to fresh 4000, but I rather see how the ball changes as the lane shine on the cover takes on the change patterns as I use it. A little earlier off of the pattern and earlier into hook part of the motion, but still retain energy in the roll phase in the back end of the pattern and dry part of the lanes. Even using in the drier part of both patterns with a hand position change to add a little more forward roll, the ball held its own and did not hook early and did not lose any energy because it still had a great overall look on the back end. If you are looking for the OG Idol replacement - this 900 Global Zen Master is for YOU!

Zen Master Better
Drilled as a step down from my Reality using the same layout it gave me the symmetrical Read more about review stating Zen Master Bettershape expected from the solid cover S77R and smoothness of the Zen.

Intended to handle more volume it is my first ball used on the fresh in league and the perfect 1-2 combination with the pearl.

More control from a multitude of angles depending on your style. My best looks were from playing the track, then moving in playing steeper angles with slower ball speeds.

As always the cover takes adjustments well, which I prefer mine close to oob with lane shine.

Wow at 59 years old
I was hung up on Asymmetrical balls for the longest time. With the Zen and the Zen Master they have changed my mind greatly. As a left hander, these 2 are the best for this low speed, low tilt and low rev player.

New Bowler
I haven't bowled for over 20 years and just go the Zen Master drilled by my local pro shop and after two practice games, I hit a 258 which the highest I've ever bowled in my life. I'm also a 155 bowler and after 9 games with the Zen Master I bowled a 196 average. Amazing ball.

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.

Excited
My average skyrocketed with the Zen, I went from a on the verge 200 hundred bowler, finishing the winter season with a 210 average. The Zen is a beast , so I’m excited to see what the Zen Master can do . #stormnation
