Roto Grip Critical
« Reply #16 on: March 10, 2016, 09:23:12 PM »
Right Handed
Rev Rate - 400
Speed - 17
PAP - 3 up 1 1/2

The new addition to the RG HP3 line is the Critical.  An Asymmetrical Hybrid.
I drilled mine fairly strong, 4 x 4 x 2 1/4 pin up and added Storm Reacta Shine. 
I'm able to use it during league as long as stay in the puddle.  Works well on the medium sport patterns.  Critical revs up fairly quick with decent midlane and arcing motion on the backend.  It is a nice ball down from the stronger Asymmetricals in the Roto line, like Hyper, Eternal and Skid.  The Critical has been a very popular choice among the bowlers at the Storm Matchmakers that we have run recently.

Length: 42ft

Volume: Medium

Type (THS, Sport Pattern etc): THS


Likes: Much smoother then expected. I was thinking this ball was going to be like the Critical Theory but no where close. Granted this is not a bad thing but if i knew this before my first few shots in league i would have shot 800 the first night instead of 760 :(

I was struggling in league b/c my house shot is very very flooded in the middle and dry on the outside, definition of black and white. This ball smoothed it out for me and my average has gone up 8pins late into the first half of the league. I literally have to try not to shoot 700 if i use this ball its so easy now.

Dislikes: Sometimes need a little more length whereas this ball will hook early if to dry left at box finish.

Critical review - Mark Tarkington

Ball weight:  15
Rev Rate:  400
Ball Speed:  17.3
Axis Tilt:  7
Axis Rotation:  45*
PAP:  3 3/4 horizontal, 7/8 up
Layout:  40 x 3 x 50

Not having really rolled the Critical Theory, I wasn’t sure what to expect from the Critical.  I really wasn’t sure what kind of layout to use on this one, but I decided to make it really even and heavy rolling. 

My first attempt on the lanes was not good, I was on a pair of lanes following league and it just wouldn’t shape.  It was either flat or left at my toes.  I couldn’t get the ball to give me any kind of consistent motion.  Being a bit discouraged, I had to put it away.

My next attempt was on a THS and this ball found it’s rhythm!  It is smooth and even and does not jump when it encounters friction.  I was able to start it in the middle of the puddle and just send it right and it would just bend back to the pocket.  The pattern held up and I never really had to make any major moves throughout the night.  I really like this ball on a THS, so it’s always in my bag on league night.

I did have the opportunity to use it on 47’ Scorpion as a ball down from my Menace and it worked rather well.  It was smooth and controllable, when I encountered over/under with the Menace.  This gives me some hope that the Critical will work well on longer sport patterns, especially since it doesn’t jump on the friction.

I’m really liking the Critical thus far and really look forward to trying it on many other patterns.

The Critical is the first asymmetrical ball released in the HP3 line of Roto Grip bowling balls. The Critical is advertised with a 67MH cover, that has a finish of 3000 abralon and is purple green and grey in color. This hybrid cover is two parts pearl, and one part solid. The Critical uses the same Triliptic Core that was in the Theory line of balls a few years back. The Critical has an Rg of 2.49, a differential of 0.058 and an intermediate differential of 0.013 in 15 lb balls.
I used a very aggressive layout on my Critical of 3 ⅝ x 6 x 2 ½. I went with this layout to give me a ball that blends those over walled league conditions. The Critical didn’t disappoint. In fact, I was able to shoot 300 with my Critical and average 255 in a tournament, that was bowled on the style of lane conditions that I drilled the Critical for. The early even ball motion doesn’t over-react on push shots that get to the dry too quickly, and doesn’t under-react on pull shots that stay in the puddle of oil on over walled house conditions. I  took the box finish of 3000 down a bit with Storm step #1, as I didn’t want the ball to cover too many boards. The Critical gives me a completely different reaction than anything else I have in the bag. The biggest thing to keep in mind is that surface texture is more important to overall board coverage than what layout option is. Layout options, give the bowlers the chance to create a desired shape to the overall board coverage that the cover texture is finished to. The only down side to a layout like I used on my Critical, is it makes the ball very specific, which is what I wanted anyway. When my Critical becomes too much, I can step down to my Asylum for a 1-2 punch.
The Critical gives bowlers a chance to drill an asymmetrical ball, at the HP3 line of products price point. The cover is very adjustable, and can be changed to meet the bowlers need of traction and friction based on conditions. If you had any of the previously released Theroy line of balls, then the Critical is a chance for you to bring back a blast from the past.
