Tourna tennis strings compared
Every Tourna string bed on the bench — 6 setups rated across eight axes, including arm friendliness, which is the axis most string charts leave out.
How the range scores
Across these 6 beds the range averages 7.7 for spin and 5.7 for arm friendliness. Its strongest axes are spin (7.7) and precision (7.5); its weakest is arm friendliness (5.7). That makes it middling on arm friendliness — neither a comfort range nor a punishing one. Gauges represented: 1.23 · 1.25 · 1.30 mm.

Each row is a string bed rather than a reel: a full bed of one string, or a named hybrid. Axes are spin, power, control (flat), precision, feel, sound, longevity, arm friendliness, each rated 0–10.

Matching a string to your racket
A string only makes sense in a frame. A stiff polyester in an already stiff, powerful racket is the most common cause of arm trouble in club tennis, and the same string in a flexible control frame can be excellent. The finder scores the pairing rather than the string alone.
