Comments about Roto Grip Infinite Theory:

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!

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.

This ball is only usful if there is a TON of oil! And I mean a S WORD load of oil!!! Unless ur a tweener, this ball is very hard to keep on the lane with anything less than a lot of heavy oil.

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!

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.

I really like the roto grip infinite theory. I have been bowling since I was twelve and I have never bought a new bowl. I learned to bowling during the urethane age, and I never could find a bowl that fit my style of bowling. the infinite theory is strong and consistent.

Great on little oil. but with a heavy inside oil if you go outside it came back like [*].

Ball is amazing in the midlane and off the spot its hits like no ball i've ever thrown.

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.

Great ball, glides through the pins very nicely, has good reaction, is very predictable, overall a very nice ball to throw
