- Description: Following the huge impact on the market made by the original Roto Grip Theory, Roto Grip has created the Infinite Theory. This ball is for bowlers looking for a smoother glide through the heads with strong motion through the pocket. The Triliptic core helps the ball get into a roll easier while the Infinite theory's triple elliptical shape creates consistent axis migration and predictable ball motion giving the consistency needed. This ball also provides more energy transfer from the ball to the pins, increasing pin movement and therefore increasing strikes. The hybrid coverstock gives added versatility while the polished surface will float the ball effortlessly through the heads with a hint of Abralon for the benefits of a solid.

Infinite Theory Complements Theory By SenorRotoGrip from Grafton,Ma
Reviewed on: 3/7/2011 Verified Reviewer Pros:Attractive Design, Flawless Surface Best Uses:Tournaments, Local Bowling Alley, Upgrade Describe Yourself:Pro Bottom Line:Yes, I would recommend this to a friend I drilled the Infinite Theory using a 4 1/2", 75 degree pin/pap layout, MB 5" from pap, pin above my ringer finger, cg in my grip line below the fingers, no hole. My intent for this layout was to be able to change to the Infinite when my Theory began hooking to early. The only difference between the Infinite and the solid Theory is the cover on the Infinite is a 1500 polished hybrid. This will get the ball through the heads smoother and also provide for more length as the lanes dry out. On a normal, 39' house shot, I had to start 5-8 boards right of where I played my Theory. This was the result of my layout providing a little more length down lane. The move off the break point was smooth. Pin hit was hard with strong ball continuation through the pins. As is the case with most polished balls, the Infinite did squirt a little when I got it into the oil too early. Overall an excellent complement to the Theory. Was this review helpful to you?

All I have to say is WOW! By Doc from Goose Creek, SC
Reviewed on: 9/11/2011 Verified Reviewer Pros:Attractive Design, Great Weight, Flawless Surface, Comfortable Grip Best Uses:Upgrade, Local Bowling Alley, Tournaments Describe Yourself:League Bowler Bottom Line:Yes, I would recommend this to a friend I've been bowling on and off for 26 years and could never get the right type of finish to match my delivery and rotation. I've either had to slow down rotation (flatten it out) or I've had to reduce ball speed. The last league I participated in was over 7 years ago, so I really haven't picked up a ball since then. (I actually threw out my bowling epquipment because I was done with league play and I was frustrated) Recently I picked the sport back up again, going once in a while with friends and my family. I chose to use lane balls, yuck, but I wasn't scoring much worse than when I left bowling 7 years ago (135-175 games). I got the itch again, so researched a ball and found the Infinite Theory. Brought it to the pro at the alley for drilling. My first 6 games are in this order: 186, 155, 248, 220, 214, 230. This ball is amazing! I feel very confident with it. The best part? The harder I throw it, the better it does! I can miss my mark by 4-5 boards and it just explodes back to the pocket. I know you will be pleased! It slides through the oil about 2/3 of the way down the lane and then it grows teeth!! Love it! Was this review helpful to you? Yes / No- You may also flag this review.

Great Movement By Joe the Pro from Tucson, AZ
Reviewed on: 6/3/2011 Verified Reviewer Pros:Pro Shots, Great Weight, Attractive Design, Flawless Surface Best Uses:Tournaments, Upgrade, Local Bowling Alley Describe Yourself:League Bowler Bottom Line:Yes, I would recommend this to a friend I use this ball for lanes with heavy oil. What i like most about this ball is if you miss your mark by a board or two it wont makr much differnce. the only con is that when the pattern breaks down the balls hook gets too difficult to manage.

Great Benchmark Ball By Jeff Mersch from Orlando, FL
Reviewed on: 2/8/2012 Verified Reviewer Pros:Strong Core, Clean Cover Best Uses:Tournaments, Local Bowling Alley Describe Yourself:Pro Bottom Line:Yes, I would recommend this to a friend Image Submitted by Reviewer:Customer Image (Great Benchmark Ball) Layout on the ball is dual angle layout 35x5x65 with no balance hole. I am a left handed tweener with a 325 rev rate. The infinite theory is another great ball from Roto Grip. The core is fairly strong and starts up pretty early. The hybrid cover is very clean in the front and strong on the backend. This ball is very versatile. I have used it with all different kinds of surfaces on it. I would consider this ball a great benchmark ball to give bowlers a great read on all different types of patterns. I used this ball on Kegel's middle of the road 39 foot pattern and it gave me the best look out of all the balls in my bag. It gave me plenty of mid lane roll to generate enough entry angle to get max carry. Jeff Mersch Roto Grip Amateur Staff PBA Member Was this review helpful to you?

Finally! By Litcher from Clare, Michigan
Reviewed on: 3/11/2012 Unverified Pros:Comfortable Grip, Attractive Design, Flawless Surface Best Uses:Local Bowling Alley, Tournaments Describe Yourself:League Bowler Bottom Line:Yes, I would recommend this to a friend I finally found a ball that fits me. I'm a 170 bowler that have problems with consistency. I bought this ball and had it drilled for easy through the heads with a strong back end. That's exactly what I got. This ball made me look good. After a couple of practice games to find my mark, I rolled 233,200,212 in the first 3 games of league play. If I was off my mark the ball still found the pocket and hit like a truck! I never had a ball hit as hard as this ball hits. Thank-you RotoGrip! Was this review helpful to you? Yes / No- You may also flag this review.
