MVP says this about the Vertex: "The Vertex is more understable than its Axiom Theory cousin, but has a nice ending fade to settle it down at your target. Specialty uses include high gliding lines, hyzerflips and turnovers, and low-power escape shots where easy precise distance matters. An understable midrange can add possibilities to any bag, whether you're an expert carving up wooded tunnels or you haven't yet found that easy straight thrower you desire."
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.
PDGA Disc Specifications
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|
