The Kastaplast Grym is the neutral counterpart to the Grym X — 13 speed, one of turn, two of fade.
Those numbers put it in the part of the distance-driver bracket that actually flies straight when you throw it right. With enough power it straightens through the middle and finishes moderately instead of fading out hard, which makes it a distance disc rather than a utility disc. Five glide is standard, so the range comes from speed. Thirteen speed is a real requirement — underpowered, the turn never shows up and you are throwing an overstable disc by accident.
How much the Grym 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 Grym was certified. Each card names discs that share the number, so you can feel it in the hand.
