The original Rotaryâ„¢ core can be found once more with an all new coverstock, Sure Grip Revelationâ„¢ Reactive.  This unique coverstock is a pearl/solid reactive combination that utilizes the benefits of a Solid & Pearl Reactive.  This is a great benchmark ball that is ideal for numerous conditions.

If the RS Series packed too much punch for you at the breakpoint, pick up a Silver Streak SEâ„¢ for a smoother transition to the pocket and all the hitting power you will ever need.

This ball is very similar to a Fired Up that I have drilled similar except it reads the midlane a little earlier and has a little smoother backend  Because of the drill and my bowling style, this is a ball that's great on medium to dry lanes.  On a fresh medium house shot, this ball is $$$$ for me and it deals with carrydown a little better than the Fired Up because the coverstock is a solid / pearl hybrid.  On heavier / longer patterns this ball tends to scoot on me unless I back my speed way down and use more forward roll.  This ball has a very strong, but controllable backend reaction to it and when it hits the pocket, it strikes alot (except for the occiasional solid 9 and ringing 10.)  This ball also had trouble storing energy for me if the heads are burnt up too much, which is not surprising given the coverstock is a solid/pearl hybrid.  All in all, another great ball from Roto Grip and a definite winner on a fresh medium to lighter THS for me.
