Most Innova molds are designed for a variety of uses and shot shapes. The Rollo, on the other hand, was designed with one, specific shot in mind the roller. Our latest Mid-range is a disc that just about any player at any skill level can roll. Low-power players can get it down on edge with relative ease to add distance in the open. Medium-power players will use this disc for more finessed throws where a low-ceiling or awkwardly placed obstacles make roller the best play.
