Prodigy says this about the X4: The Prodigy Disc X4 is a slightly understable, low profile, high speed distance driver. It is great for players with lower arm speed that are looking to gain more distance. The X4 is designed to hold a turnover even at a lower speed. The X4 performs very well at low heights and in tunnel shots. For players with faster arm speed, the X4 will flip later in the flight path, and is perfect for long wooded shots or accurate turnovers.
The velocity required to reach a disc's optimal flight path. Range: 1 to 15.
The measure of lift generated by a disc to stay aloft. Range: 1 to 7.
The velocity, relative to the speed of the disc, required to cause the disc to turn with the direction of spin. Range: +1 to -5.
The low-velocity stability that causes a disc to hook at the end of its flight. Range: 0 to 5.

Phases of Flight
|As the disc slows and spin decreases, the disc pulls out of turn and begins to hook at the end of flight|
|The aerodynamic profile turns the disc with the direction of spin during the high-speed phase of flight|
|The initial thrust forward during the high-speed phase of flight|
