For my game, med speed - more forward roll then side roll, both balls drilled 4 1/2" from PAP above ring, I have the Reign 3-2 to 4-2 stonger then the RFP depending on lane surface with the Reign having slightly more mid lane and a stronger backend. My 5" to PAP above fingers Hyroad fits right between these two with a smoother backend then the Reign.
