Nishi Discus Super Series
Three discs, one family name, and real differences that matter in competition. Here is what every thrower and coach needs to know before stepping into the ring. If you'd like the brief version, check the video out here.
The All-Around Standard
The Super Competition is the most forgiving disc in the lineup and the easiest to recommend broadly. Its balanced moment of inertia means weight is distributed evenly, giving the disc a stable, predictable flight that rewards clean technique without demanding elite spin rates. It releases cleanly off the hand, holds its angle through the flight path, and does not punish small errors the way higher-MOI implements can. For throwers still building their technical foundation, that consistency shows up directly in the mark. For advanced throwers, it handles aggression well.
Fun fact: 4Throws is the only US company offering the Super Competition in the 1.6 kg high school boys weight.
Built to Float
Moment of inertia describes how mass is distributed relative to the disc's spin axis. The Super High Moment concentrates mass toward the rim, creating exceptional gyroscopic stability in flight. Once it leaves the hand with good spin, it resists the tilting forces that cause a disc to collapse off-plane early. The result is a disc that floats longer than anything else in the lineup, which in good conditions translates to carry well beyond what the same throw would produce with a standard implement.
This makes it the go-to for technically sound throwers who do not generate elite hand speed. The tradeoff is that it magnifies release errors. A bad angle stays bad for the entire flight. Clean throwers will love it; throwers still correcting their release will find it unforgiving.
Built to Drive
Where the High Moment asks the disc to carry for you, the Super High Momentum is built for throwers who generate it themselves. Its more center-biased weight distribution allows the disc to accelerate through the release faster and penetrate through the air with a lower, more aggressive trajectory. It does not float. It drives. Throwers who move well, produce high linear speed through the circle, and release with a fast explosive finish will get the most out of this disc. Into the wind it holds its line well. With a tailwind, it is exceptionally effective.
