Comments about Roto Grip Theory:
FIRST ROTO GRIP BALL HARDEST HITTING BALL THAT I HAVE SEEN IN ALONG TIME ..MY FIRST SERIES OUT OF THE BOX 715 FINISH LEAGUEWITH 212 AVERAGE ..
Comments about Roto Grip Theory:
This ball is just amazing. I have owned several Roto Grip balls and this is my favorite so far. This ball is very similar to my Roto Grip Cell. Has just about the same reaction but is much stronger through the pins and doesn't have any deflection. I have my ball drilled the same layout as my Cell to go long and strong. I average 231(house) 216(sport) and i had no problem averaging 240 right out of the box. My first tournament with the ball i won with a 809 series.

Comments about Roto Grip Theory:
I have been doing research on the internet to look for a ball as an upgrade from C-system 4.5. My c-system slides too much and it just does not work for league because they put so much oil on the lanes. After making adjustment, sometimes I just can't get the c-system to hit the pocket. But with the Theory, it rocks! Trust me, this is perfect for stroker who has a lot of speed but not much hand. You can't go wrong with Theory. However, one thing I noticed was that it quickly soak up oil. You gotta take good care of it. Otherwise, it will die very soon.

Comments about Roto Grip Theory:
I am a full roler. Yes we are still out there. Out of the box. 784. Very smooth.No wet dry to deal with. As lanes broke down very smooth, easy transition. Glad the ball is in my bag. Could not be happier.

Comments about Roto Grip Theory:
My specs: left hander, 230 plus average 3 & 5/8th and 1/16th up, 17+ plus ball speed ,bowl in several leagues in 2 counties and bowl in about every tournament locally and state and nationwide.
Layout recommendation from Mike Sinek: 55x4 ¼x60 pin below middle finger, condition and no weight or P-hole. First reaction was the ball roll similar to the cell, but a more total hook and a lot less deflection going through the pin rack. After using it for about 20 games the reaction, unlike other solid reactive balls, has not change one bit and has not diminished one bit. Overall, a continuous arching ball with a ton of hitting power in the back end that shows no signs of slowing down. Thanks to Mike and Matt at Roto Grip for the support.
