MVP Relativity. Cheap price fast shipping in the US. MVP says this about the Relativity: The Relativity has a useful understable profile that allows controllable turnovers, rollers, and high-line distance shots. While its net landing spot will normally be to the understable side of its launch point, the Relativity’s high-speed design forces an ending fade that nicely pans out of turnovers and high lines to prevent unwanted rollers.
