Our Reaper Edition Kastaplast K1 Glow Falk carries our flame vortex stamp on an understable control driver named after the Swedish word for falcon. K1 Glow plastic keeps the grip Kastaplast is known for while adding a charge that holds up for late, dark rounds.

Flight Numbers: 9 / 6 / -2 / 1

K1 Glow is grippy even by Kastaplast standards, tacky enough that two of these discs stick together if you're not careful stacking them in a bag. It's durable through repeated tree hits, and the glow charge holds bright and long after a headlamp or flashlight tops it off, so a night round doesn't mean losing sight of it in the rough.

Throw it with a little hyzer and it flips to flat, glides a long way, and finishes with a gentle fade into the circle. On anhyzer it holds that line and only settles back to flat right before landing, which makes it a strong tool for sweeping turnover shots. Full power backhand throws will push this one past neutral into a hard turnover, so ease off if you want it to hold.

New and intermediate players get the most out of it as a control driver that's forgiving of an early release, and slower arms will find the turnover comes easier than a Valkyrie or similar 9 speed. Big arm throwers should treat it as a specialty turnover disc rather than a workhorse fairway.

Want the same flight without the glow? The Kastaplast K1 Falk flies identically in standard K1. Prefer a softer, grippier feel? The Kastaplast K1 Soft Falk is worth a look. Shop the full Falk collection.
