MVP says this about the Catalyst: "The Catalyst is a perfect starter for big distance. Its stability profile lends itself to being incredibly useful even when underpowered. Catalyst is significantly less understable (more stable) than its 21.5mm counterpart, the Orbital. High power throwers will be able to control rollers, sky anhyzers, and tight turns, while average to low power players will get easy distance with great glide, and a power responsive amount of turn-to-straight. The Catalyst is molded with the same core and nice even dome as the Octane, yielding extra glide for maximum distance shots."
Flight Metrics
Speed
The velocity required to reach a disc's optimal flight path. Range: 1 to 15.
Glide
The measure of lift generated by a disc to stay aloft. Range: 1 to 7.
Turn
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.
Fade
The low-velocity stability that causes a disc to hook at the end of its flight. Range: 0 to 5.
I own several of these and love them, they fly just a little farther than my Wave or Crave. My home course Tocobaga Maximo in St Petersburg Florida has a lot of foliage and I tend to lose them often, so I replenish my supply when 1010 has a sale and either bright orange or pink discs are available.
