Roto Grip Theory Review

[Rob Haverstock]

Using the Dual Angle layout method, I drilled my Theory 60/5/40 with a P2.5 balance hole.

 

So far what I am seeing from the Theory is a strong, smooth reaction. Sometimes with this layout I get a little over/under but not with the Theory. The Theory has great continuation, and keeps the pins low. So this makes for great carry.

 

Hank and the rest of the Roto Grip staff has come up with a new "Theory" and the Theory is going to be great for the industry.

ThEorY ball review #1
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.
