"The differential in the Reign core is lower, so I would actually expect it to have a little less backend. Of course, this is without knowing the core shape."
If I can believe the webpage that lists the Reign as having the CAM core, and looking at the Roto Grip Empire - International Ball with CAM [Controlled Axis Migration] core, expect long and strong.
