Data pack
Seven-iron shaft test data
One seven-iron head, eight shaft configurations, hit back to back on a launch monitor in October 2024.
Coming soon
What’s included
- Shot-level data for each configuration (about 170 shots): ball speed, launch, spin, carry, and dispersion
- Averages and best-shot comparisons by shaft
- Which shaft each color band was
- A short write-up of what the test showed and where it falls short
- CSV files plus a PDF summary
My own shots only. One golfer, one session, one head.
