Manufacturer’s Stability Rating: Stable

Known for its lack of glide and good high-speed stability, yet without tons of fade, the Berg is a slow and straight flyer that won't play tricks on you. Even on windy days.

Kastaplast's super durable material with a nice combination of firmness and gumminess.

Understanding stability ratings

F&F Stability Rating uses the displayed turn + fade numbers, including plastic-specific overrides:

  • Understable: −1 or less
  • Stable: above −1 and below 2
  • Overstable: 2 or more

This keeps our filters consistent across brands. Actual flight varies with the thrower, disc wear, and conditions. Missing turn or fade displays “Stability not available.”

Manufacturer’s Stability Rating uses the brand’s own wording, which may differ from ours. We omit it when unavailable.
