The Roto Grip Disturbed is the newest entrant into the H3 line. We could easily end the review and test results by summarizing it up in one sentence: This ball just flat out hooks. For the sake of our readers, however, we will go into more detail.

We started on the heavy test pattern and never had a doubt this ball was going to make it back to the pocket. Shots missed right usually result in 2-10 combinations or washouts, but not with the Disturbed. Even when we thought we threw it out the window on this pattern, the Disturbed screamed back to the pocket. The 2000 Abralon box finish can put an indention in even the slickest oil pattern. Bowlers who compete on lots of volume or want to see more total motion will have the most to gain from the Disturbed.

Moving to the medium pattern, Stroker had the best reaction. His lack of revs were what was needed to get this rough finished ball down the lane. Tweener’s high ball speed got him in the pocket to start, but soon after it was too hard to keep it off the nose. Cranker had no chance from the start and after a shot or two, he took it right to the spinner. He added Storm Step 2 compound and made that same adjustment to Tweener’s test ball. The added length helped, but the Disturbed still had too much hook for our liking on this pattern.

The short dry pattern made Cranker give up trying to make it work after he raised the surface to 4000 Abralon and laid into the Disturbed with Storm’s Reacta Shine and still could not keep it right of the headpin. Tweener and Stroker made the same surface adjustment and actually had a fair reaction on this pattern.

The Disturbed beat our sport pattern into submission. The pure raw strength of this ball overpowered our pattern and made it look fairly easy. Longer sport patterns or ones with higher volumes of oil will be right up the Disturbed’s alley.

Performance Ratings

NameValueComments
Torque6.5
This ball offered a nice amount of reaction at the breakpoint for such a strongly shelled ball. There are plenty of other ball options for bowlers looking for more skid/snap.
Length11
The cover creates traction quickly on any type of lane condition. Polish will be a must for slow speeds or high rev rates on medium patterns.
Back End15.5
The back end hook is one of the larger ones from a sanded Roto Grip product. Even at the low box finish, this one still has a good move at the back.
Total Hook54
The Disturbed can hook with the big boys in the HP line. This ball will be ideal for long and heavy type oil patterns.

Strengths

Raw, unadulterated hook is the biggest asset of the Disturbed. When we managed to get this one through the front, it had no problem storing enough energy to kick out the corners.

Weaknesses

Short dry patterns or when the heads start to go away will be disaster for the Disturbed at the box finish. This ball hooks early and often and needs some help from the lane lubricant.

Overall Summary

This ball hooks as much as any ball in the Roto Grip line. Bowlers who prefer symmetric cores and are looking for a monster oil ball need look no further than the Disturbed.
