Putter · Very overstable · Traced from the official flight chart
The Kastaplast Jarn is a speed 4.5 putter with glide 3, turn 0 and fade +3, for an estimated maximum distance of 68 m / 223 ft. With fade outweighing turn by 3 points, it is a very overstable putter: it holds a straight-to-left line even when thrown with power, resisting the wind rather than turning over. The flight path above is traced directly from Kastaplast's official chart, so it reflects the disc's real charted flight rather than a calculated estimate.
At speed 4.5, this is a putter in the midrange range. It asks for only moderate arm speed and stays controllable for the majority of players. Its glide of 3 gives it steady, controllable float. A turn of 0 means it resists turning right even at full power, and a fade of +3 gives it a strong, reliable hook back to the left at the end.
Stability: Very overstable (rating +3). It holds its line in a headwind and resists turning over, making it a dependable wind fighter.
Backhand & forehand: The extra fade resists the turning force a forehand imparts, so it doubles as a reliable sidearm disc; on a backhand it finishes dependably to the left for a right-handed thrower.
Skill level: It is best suited to players who can bring it up to its rated speed; a slower arm will see it finish left early.
