Luke Rosdahl Rated Rumble: Roto Grip Idol vs 900 Global Zen Master Bowling Ball

roto grip idol vs 900 global zen master bowling ball

My Rated series was designed to give you the ability to compare any ball vs any other ball, but I still receive a lot of questions about specific comparisons, so rather than making you dig around in the playlist, I’ve decided to combine several of the most popular or requested comparisons into single videos! If you have a comparison you want to see, put it in the comments and I’ll make it happen!

Roto Grip Idol Bowling Ball Ratings For Hook, Length and Backend

The Idol features the MicroTrax S18 solid coverstock and now iconic symmetric Ikon core.  MicroTrax is basically NRG or nano tech, and it creates a very strong, early, and continuous reaction.  The Ikon core comes in at a 2.49 RG and an .052 differential in 15 pounds, and has a quite recognizable strong rolling, rounder and slightly forward shape down lane.  The Idol has seen a lot of tv time over the last couple years for Kris Prather and Anthony Simonsen and was in Francois Lavoie’s hands when he won the 2019 US Open.  The high amount of traction with the ultimate amount of control makes the Idol an IQ Tour Solid on steroids.  With 1 being the lowest and 10 being the highest, I rate the Idol a 9 for hook, a 4 for length, and a 4 for backend.  It’s become a higher end benchmark ball that is the standard for controllable big hooking asyms.  It’s closest to the Axiom in hook, the Phaze 2 in length, and the Omega Crux in backend.  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.

The Zen Master features the S77 Response solid coverstock and incredibly strong symmetric Meditate core.  Angel’s layout as always is 5 x 3 ½ x 3 ½, putting the pin above her bridge, mine is 4 ¾ x 3 ½ x 3 ½, putting the pin in my ring finger, and because this is a symmetric core, the cg placement doesn’t matter.  Global covers give you some semblance of their strength with the number in the cover name, S77 is getting up on the strong side and is currently Global’s second strongest cover, and it feels like it’s in Incite territory, or like the solid version of that coverstock would be the best frame of reference, it’s really strong, early, and smooth.  The Meditate core is the same one from the Zen, 2.49 RG and an .051 differential in 15 pounds,, and it’s very strong, early, and rolly, reminds me a lot of the Centripetal HD core from the Son!Q and Super Son!Q, so I think that’s why the Zen has been so popular, it’s the best of several different worlds.  It’s a really smooth and blendy ball that’s squarely in Phaze 2 territory.  I think it’s actually a bit earlier and smoother, it feels like it’s trying to roll a little sooner and it definitely rolls a bit heavier, but realistically the difference is pretty small.  There aren’t a lot of nuances to talk about here, the ball reaction is pretty straightforward. It hooks a lot and is really smooth.  For ratings, once again it’s solidly in Phaze 2 territory but I think even a bit stronger and earlier, so approaching Axiom strength and length, but a bit slower, so the Zen Master gets a 9 for hook potential, a 4 for length and a 4 for backend.  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.

The newly created Ikon™ Core has pushed the symmetrical dynamics in the HP3 line to a whole new level. Measuring in with an rg value of 2.49 and a differential of .052, backend motion will not be a problem.

In testing and development we stumbled upon our strongest blend of Nano technology for the Roto Grip Brand to date, MicroTrax-S18. With tweaks in formulas and mix ratios we have created a coverstock that provides even more traction and is overall more aggressive than the Micro DNA Coverstock.

Bottom line, in the HP3 line we have been looking for the next generation of Haywire. Needless to say, the new IDOL is that and then some. You will see a similar motion in the midlane compared to the Haywire, but with the new core and new cover you will see more overall hook.

The S77 Response™ Solid Coverstock was the obvious choice to follow up on the success of the S77 Response™ pearl coverstock. The Solid version of this cover will provide the most overall hook we have ever put in the 800 Series. The Zen Master™ will be a great ball to use on medium-heavy patterns.

The Meditate™ Core is the biggest core we have ever put into a bowling ball!! A bigger core means more hitting power combined with a more consistent reaction. Throughout testing the Meditate™ Core provided that wide “footprint on the lane that all bowlers love to see. The Zen Master™ pushes the limits of core dynamics.
