Manufacturer’s Stability Rating: Stable

One of the first things you look for when building a bag is a stable and reliable fairway driver. Because if you master the fairways, you master a big part of disc golf. The Idog is the right tool for the job, it will help you stay inbounds on tricky tee shots and keep long approach shots on target.

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.
