Material properties
Playing profile
A TTDNA blade rating measures how much of the named characteristic a blade has. For descriptive rows — flex, stiffness, vibration, head heaviness, weight, thickness, carbon feel, softness, technique requirement, spin sensitivity — a higher number means more, not better.
TTDNA ratings are normalized comparison values, not laboratory measurements. They are built from published specifications, technical sources and structured product evidence, converted to one 0–100 scale. Where a directly comparable measurement is unavailable, the value is an evidence-based estimate. Overall-style scores are composites of several characteristics. Methodology
