The Yikun Shu is an understable midrange with high glide. Five glide at 4 speed means it stays up a long time for a midrange, and two turn means it drifts right for most of that time.
It is a large-diameter mold — 218mm, the widest Yikun makes — with a thin rim, and Yikun’s description is unusually candid about who it suits: thrown slowly and on a hyzer it is a good disc for a beginner to throw straight, finishing gently right and landing softly, while more power will turn it over and roll it. Infinite reviewer averages of 4 / 5 / -2.3 / 0.9 confirm the rating. That is a genuine two-audience disc — the same mold reads as straight to one player and as a turnover to another.
That puts it in the turnover-midrange and first-anhyzer slot, with rollers available if you throw it hard. One fade is not much of a finish: in a headwind it flips and keeps going, and it will not hold a hyzer line the way a stable midrange does.
Yikun is a Chinese manufacturer based in Ningbo and the first Asian company to have discs PDGA approved; its lineup is named for Chinese mythology and culture, and the PDGA registers this mold under the characters 耳鼠, of which the retail name is a shortening. Yikun does not publish an English meaning. Approved in September 2020 and made in Tiger Line, Phoenix Line and Dragon Line.
How much the Shu turns and fades depends on how hard it is thrown. These three shapes are drawn from the manufacturer’s numbers, not from measured throws.
Measured by the PDGA when the Shu was certified. Each card names discs that share the number, so you can feel it in the hand.
