EV-7 says this about the Penrose: The Penrose is EV-7's debut putt and approach disc. It has reliable high speed overstability and resistance to turn, but is uniquely straight with consistent fade at lower speeds on the putting green. With a slightly deeper profile, small bead, and smooth feel, the Penrose fits the hand comfortably, inspiring confidence for both putts and upshots.
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|
