As the weak are eliminated, an EPIC BATTLEtm rages on! Roto Grip has forged the most effective weapon for the battlefield and puts it in the palm of your hand.

Armoring the EPIC BATTLEtm is the new Ultimate Visiontm solid particle coverstock. The unique blend of a super strong base reactive material in combination with a light particle load gives you traction in the heaviest of oils.

At the heart of the Battle is the new Maximus IItm weight block. This low RG (2.48) / High Differential (.050) core creates a Mass Bias Differential of (.026) that generates an earlier move in the lane, then delivers a bone-crushing backend reaction.

Condition used was PBA Regional Pattern 1(40Ft) and THS(38Ft)
Pattern #1 Lane condition was synthetics(Brunswick).
On this pattern the ball was nice and smooth reacting and was predictable at the break point. As the oil transitioned the battle got a little over under due to the surface. On a dull surface this ball is a beast and is almost unaffected by the transition.
THS is Wood lanes and Brunswick synthetic both conditions are med oil for our areas THS
On wood this ball gives a strong smooth backend with consistent read.                              Synthetics with a little more oil seemed to have little effect on this ball compared to the wood lane. The ball  played rather similar on both surfaces.

Line being played
Pattern #1 15/ 8 @ 38-42ft on fresh                                                                               THS 20/5 @ 37 ft on fresh

Overall Thoughts
This ball is great for use on med to heavy oil pattern and has great readability and control. Ball has great traction and carry. I have tried a few different surfaces and it has been responsive to the changes.
Compared to the Oracle with a very similar drilling This ball is stronger and more aggressive throughout the entire lane. For me it is about 5 boards stronger then the oracle.

 X-BLEM ( which means it's a second made ball, not a first made ball.
 
 I bought this ball hoping to use it on a Heavy Oil Pattern. Well, that plan backfired. I've had this ball for a couple of months now and i still can't get it to hook in heavy oil. I had to shine the ball up to get it to do something. But that's not what I bought it for. I don't mind having it shined but, it doesn't work very well in heavy oil. It works fine on Medium oil or Light oil. I don't know if it's from the ball being an X-BLEM or what, I just can't get it to hook on heavy oil. If you were to buy a roto grip ball, make sure it has stats that fit your bowling style or type. Roto Grip Balls are nice balls so I'm not saying that they are bad balls. If you were to buy a Roto Grip ball, i think you will be satisfied with it.
